Information about CI failures on pull requests to Mbed TLS

by Gilles Peskine

Hello, If you've made a pull request to Mbed TLS, you've noticed that some of the continuous integration happens on a private server run by Arm. For jobs that ran since yesterday, if there are failures, you can now see the name of the failed tasks next to “PR-NNN-head TLS Testing” or “PR-NNN-merge TLS Testing”. See https://developer.trustedfirmware.org/w/mbed-tls/testing/ci/#identifying-je… for more details. If this isn't enough, an Arm employee can copy the logs from the server. Please ask in a comment. We hope to post logs automatically (https://github.com/ARMmbed/mbedtls/issues/3633) but I can't give a due date for that. We are planning to move to a public server run by TrustedFirmware, but this can't happen until some time in 2021. Please bear with us in the meantime, and thank you for your contributions. -- Gilles Peskine Mbed TLS developer

Hello everyone, I want to set up a webserver on my ESP32 Dev Module based von MbedTLS. Therefore I view the ssl_server example on github. Now my question: How can I connect the ssl_server to my local WIFI-network. What extra code do I need? And where is the SSID and the password configurable? Thanks for your help!

DTLS server

by Mehdi Karimi

I am using v16 of the mbedTLS library to setup DTLS server. However, I observe that the handshake does not work well and there are several issues starting with the cookie exchange. Do I necessarily have to update to the latest version of mbedTLS? Are there known issues with DTLS server setup using previous versions (as far as I could tell from the ChangeLog). Thanks Mehdi

Re: [mbed-tls] Proposed change: no longer credit contributors in the ChangeLog file

Hi Gilles, as you said: Git is public. As long as it is kept public there's no reason to "duplicate details".

Re: [mbed-tls] Building a collaborative Mbed TLS community

by Frank Bergmann

Hi Gilles, when I ask in our team to review a PR I usually provide an estimation about it. Of course a time base estimation and not an agile one in values of complexity. ;-) One could also provide an estimation about priority. Maybe these tiny rules may help somewhat.

Building a collaborative Mbed TLS community

by Gilles Peskine

Hello, Historically, Mbed TLS has been maintained by Arm as an open-source project, accepting external contributions, but with with priorities and plans mostly driven only by Arm. Since earlier this year, Mbed TLS is an open governance project under the umbrella of TrustedFirmware, with the objective of making it a community led project, allowing community to contribute and collaborate on the design and development of the project. In practice, however, the project effectively still has some barriers of entry. We would like to lift these barriers. The Mbed TLS team at Arm have already identified some concrete actions, filed on the Mbed TLS epic board https://github.com/ARMmbed/mbedtls/projects/2#column-10667107 under “Facilitating community contributions”. A few more should be up soon as the result of some internal brainstorming. We've also identified some problem areas which we're tracking as separate topics. * Probably the biggest topic: review was and is a bottleneck. We are working to streamline the review process where possible, without lowering the quality bar, and to prioritize reviews better over new work. (Having personally often been on both sides of the coin, I can confirm that having a pull request sit around for years without getting reviews is frustrating, and so is seeing all these pull request and not having the time to review them all.) We would also like to enable, encourage and value reviews from people who are not project maintainers. * We will migrate the CI to a publicly available platform hosted by TrustedFirmware. However this platform will not be available until 2021. * We are working on a new documentation platform, where we'll transfer both the information available on the current website and information that is currently recorded in an Arm internal wiki. To all of you who have contributed to Mbed TLS, who have tried, or who are considering it, what difficulties have you encountered? What else can we do to make contributing easier? Best regards, -- Gilles Peskine Mbed TLS developer

Proposed change: no longer credit contributors in the ChangeLog file

by Gilles Peskine

Hello, The Mbed TLS team is soliciting feedback on a proposed change of our contributor acknowledgement policy. Background: our current policy is to acknowledge all contributors who are not Arm employees in the ChangeLog files. This is a tradition that dates back from when the version control history of Mbed TLS (then PolarSSL) was not public. Proposed change: the ChangeLog file will no longer mention who contributed a patch (“Contributed by …”). A patch will require a ChangeLog entry only if it makes a user-visible changes, regardless of who contributed it. We will still credit reporters in the ChangeLog file, at least for security issues. Rationale: the ChangeLog file had a dual purpose: informing users, and acknowledging contributors. It will now have the single purpose of informing users. There are better ways of acknowledging contributors nowadays: the Git history is public, and your contributions are visible from your GitHub profile. (Note that we don't squash commits, and attempt to preserve authorship as much as possible when we have to rebase a patch.) Furthermore, writing a good ChangeLog entry often turns out to require some back-and-forth, so lessening this requirement will make it easier to accept contributions and to merge them faster (this is in fact our primary motivation for the change). We are also thinking of creating an acknowledgement page out-of-tree. It isn't clear yet what its scope would be, but it would include acknowledging contributions in the form of reviews, which we wish to encourage. (Please stay tuned for future announcements and discussions regarding the Mbed TLS review process.) Question to potential contributors, or people who have participated in other open-source projects: do you think that there is any value in keeping acknowledgements in a file that is distributed with Mbed TLS? Is there any value in maintaining an exhaustive list of contributors in a form other than the Git history? Best regards, -- Gilles Peskine Mbed TLS developer

Parse RSA keyfile-Error

by youssouf sokhona

Good morning to all, I am currently trying to perform RSA encryption, so I am using a file containing a public key (generated by OpenSSL) to do this. So at the beginning I use the "mbedtls_pk_parse_keyfile" function to read it, as you can see on the image below. Unfortunately, I find the following error : ERROR 3E00 : Read/write of file failed. Do someone have an idea of why I have this error ? Or should I change my way to read this file ? Thanks a lot, have a nice Weekend [cid:image002.png@01D68839.7B058100]

Hi, On those CPUs, the AES implementation in Mbed TLS is pure C, it doesn't use any hand-written assembly.

A new configuration mechanism for PSA crypto in Mbed TLS

by Gilles Peskine

Hello, As you may be aware, there is work in progress to implement support for hardware drivers in Mbed TLS when using the PSA API. These are direct calls from the PSA frontend layer to driver code, without going through mbedtls_xxx APIs and the ALT implementations. The specifications are the psa-driver-*.md files in https://github.com/ARMmbed/mbedtls/tree/development/docs/proposed and you can watch the work in progress in the “Unified driver interface: API design and prototype” epic https://github.com/ARMmbed/mbedtls/projects/2#column-8543266 . When an algorithm is implemented in hardware, in most cases, it is unnecessary to include a software implementation, and it should be possible to exclude the software implementation from the build to keep the code size down. Unfortunately the current Mbed TLS configuration mechanism does not support this, because it does not distinguish “I want AES” from “I want mbedtls_aes_xxx”. So we need new compile-time options to convey “I want PSA_KEY_TYPE_AES in my application but I don't care whether it's done in hardware or mbedtls_aes_xxx”. We are going to implement a configuration mechanism to select which cryptographic algorithms are included in the PSA interface in a build of Mbed TLS. It will rely on #define statements, like the existing config.h, but with different naming conventions for PSA. You can see the specification proposal at https://github.com/ARMmbed/mbedtls/pull/3628 . Feedback is welcome. We're likely to merge this pull request soon, but even after it's merged I'll keep watching comments, or you can post feedback on the mailing list, or raise an issue on GitHub if you have a specific feature request. A major difference between the current MBEDTLS_xxx_C configuration and the new PSA_WANT_xxx configuration is that PSA_WANT_xxx is additive: if PSA_WANT_xxx depends on some other feature, enabling PSA_WANT_xxx will automatically enable that feature in most cases (the exception being when there's more than one way to enable the dependent feature, e.g. when a hash algorithm is needed but it doesn't matter which hash). This is in contrast with the current strict mechanism where enabling MBEDTLS_xxx_C is an error if it depends on some other feature that isn't enabled. We haven't decided yet, but we're thinking of changing to an additive mechanism for the whole Mbed TLS configuration in Mbed TLS 3.0. If you want to watch the implementation work in progress, it will be under the “Driver Interface: Removing unused code” epic https://github.com/ARMmbed/mbedtls/projects/2#column-9449707 . Note that the #define-based mechanism is somewhat experimental and we won't commit yet about its long-term stability in Mbed TLS. It is likely to be complemented by a JSON-based mechanism in the future. This JSON mechanism would be similar to the proposed mechanism for drivers and would allow finer granularity (for example, RSA verification without RSA signature). Arm is considering standardizing the (as yet non-existent) JSON mechanism as a PSA specification. Best regards, -- Gilles Peskine Mbed TLS developer (and PSA crypto architect)

How can I encrypt RSA private key with AES?

by Shariful Alam

Hi, I hope everyone is doing well. I am a beginner on mbedtls and cryptography. I hope you will understand if there is a lack of understanding or a rookie mistake from my part. So, My goal is to do a key-encryption key. I have an *RSA* private key file "*private.pem*" generated by OpenSSL. I want to encrypt the content of this "private.pem" with *AES* *encryption* and followed by *AES decryption *on the encrypted data. To do that, I read the "private.pem" file into a buffer and perform AES encryption. The problem is when I perform the AES decryption operation I get something else instead of the original "private.pem" data. I have a working example of AES encryption/decryption working on plaintext perfectly. So, I guess there is a flaw in my understanding of encryption/decryption of byte64 encoded string. Can someone please suggests me how can I encrypt RSA private key with AES? Thanks, Shariful

[Mbed-tls-announce] Latest release link on github

by Janos Follath via Mbed-tls-announce

Mbed TLS version 2.24.0, 2.16.8 and 2.7.17 have been released recently. Version 2.7.17 is incorrectly marked as the latest release by github. Since this happens automatically based on the commit creation dates, this can’t be fixed until the next release. We have extended the release notes of 2.7.17 to warn about this and changed the download links on the website. We would like to confirm that version 2.24.0 is the latest release and the other two are the patch releases for the 2.16 and 2.7 long term support branches. My apologies for the inconvenience and thank you for your support!

Re: [mbed-tls] Print long MPI

by Gilles Peskine

Hello, 4096 bytes is a lot larger than a typical public key. 4096 *bits* is common for an RSA key. Are you sure you're using the correct units? By default the library doesn't support the creation of MPI that are larger than 1024 bytes. This is a configuration option (MBEDTLS_MPI_MAX_SIZE), although it's uncommon to change it (a larger value is hardly ever necessary, and a smaller value won't save memory except in RSA which needs at least 512 bytes for 4096-bit keys). However mbedtls_mpi_write_file itself doesn't have any size limit.

Print long MPI

by youssouf sokhona

Hello everyone, I think you are fine during this crisis. I am working now with mbedtls modulee, and I wanted to print a function « mbedtls_mpi_write_file » to print the value of an MPI. This function works with common values. However, when I want to print an MPI which is very long (about 4096 bytes, a public key), it doesn’t work. Someone knows how to solve this problem ? Thanks a lot Best regards, YS

Re: [mbed-tls] Set an MPI and print it

by Manuel Pegourie-Gonnard

Hi Youssouf, I think you're looking for mbedtls_mpi_write_file() - just pass NULL as the file argument to write to stdout. You can use the radix argument to print out hex or decimal. Regards, Manuel. ________________________________ From: mbed-tls <mbed-tls-bounces(a)lists.trustedfirmware.org> on behalf of youssouf sokhona via mbed-tls <mbed-tls(a)lists.trustedfirmware.org> Sent: 25 August 2020 15:40 To: mbed-tls(a)lists.trustedfirmware.org <mbed-tls(a)lists.trustedfirmware.org> Subject: [mbed-tls] Set an MPI and print it Hi everyone, I think you all are fine. I am a beginner on mbedtls, and I wanted to set a dhm context. So, at first, I just want to set the value of the prime P, and the generator G. So to that I wrote the function below : [cid:image001.png@01D67AF5.D43FDE60] To check if it is correctly set, I wanted to print it to see. However, it is not the case. Do you know how to set and print the value ? Thanks, and have a good day Best regards, YS

mbedtls handshake failed

by Manu Abraham

Greetings, I am trying to connect from a STM32H7 MCU to a mosquitto peer, Can someone please help me to fix this issue that I have ? I have used the DES3 cipher to create the keys .. openssl genrsa -des3 -out test_ca.key 2048 .. Fiddled quite a bit with buffers, stack, heap and mbedtls config, eventually the communication appears to be working, but the handshake appears to fail. At the client MCU side, I see the mbedtls_ssl_handshake failed message with a return value of 0x7780 Additionally, I do see this message too: ssl_tls.c:5169: got an alert message, type: [2:40] ssl_tls.c:5177: is a fatal alert message (msg 40) But unfortunately, I am unable to make out what the error message means. At the peer, this is what i do see: 1598367067: New connection from 192.168.1.33 on port 8883. 1598367074: OpenSSL Error: error:1417C0C7:SSL routines:tls_process_client_certif icate:peer did not return a certificate 1598367074: Socket error on client <unknown>, disconnecting. 1598368366: mosquitto version 1.6.7 terminating Someone, Please help !

Set an MPI and print it

by youssouf sokhona

Hi everyone, I think you all are fine. I am a beginner on mbedtls, and I wanted to set a dhm context. So, at first, I just want to set the value of the prime P, and the generator G. So to that I wrote the function below : [cid:image001.png@01D67AF5.D43FDE60] To check if it is correctly set, I wanted to print it to see. However, it is not the case. Do you know how to set and print the value ? Thanks, and have a good day Best regards, YS

undefined reference….

by youssouf sokhona

Hello everybody, I hope you are going well I am creating a diffie Hellman key exchange program, so I am using functions like « mbedtls_dhm_init() » or « mbedtls_ctr_drbg_init() « for example. However, even if I defined the CTR_DRBG & the DHM_C module in the config.h file, and the header in my C file, I Always have error like that : [cid:image002.png@01D6770C.20370D40] Can someone help me to find out where does it come from ? Because I don’t know at all. Thanks, and have a good day

Printf with %z and %hh format specifiers.

by Paul Elliott

Hi all, I am placing into review a patch ( https://github.com/ARMmbed/mbedtls/pull/3579) which replaces some invalid size printf format specifiers, mostly for size_t. This patch utilises %zu and %hhu, both of which were only introduced in C99, which I know caused some issues with compiler compatibility at the time. The problem with printf and size_t as most will know, is that its a different size in 32 bit and 64 bit, which is what %z was introduced to safely fix. My question is to whether there is anyone on the list that is using a compiler that might not handle these specifiers, for whom this patch would presumably be something of an issue. I am admittedly hoping this is not the case, given the age of the spec, but thought it best to ask. Thanks in advance, Paul.

Re: [mbed-tls] Custom PSA API Implementation for mbedTLS tests

Hi Murat What you request may be possible with invasive changes but it is not a design goal for the PSA Cryptography API implementation in Mbed TLS to be completely replaced with an alternative implementation, while allowing re-use of the Mbed TLS build system and tests. The focus instead is to develop and implement a PSA Cryptoprocessor Driver Interface, which will allow drivers for custom secure environments to be plugged into the core PSA Cryptography API implementation in Mbed TLS. An early version of the specification of that interface can be found here: https://github.com/ARMmbed/mbedtls/blob/development/docs/proposed/psa-drive… That specification and its implementation is under active development. Let us know if you would like to get involved. Regards Dan.

Now we would like to run mbedtls tests (make check) on the PSA API if possible. When we run "make check", it includes and compiles library/psa_crypto.c file for mbedTLS's PSA API Implementation. Herein, we would like to compile our own psa_crypto.c implementation, does mbedtls build system allow us to include custom PSA API Implementation to run tests? Thank you. Murat

Re: [mbed-tls] MBEDTLS_ENTROPY_HARDWARE_ALT, mbedtls_ctr_drbg_seed() freezes ?

by Manu Abraham

Replying to my own post, I did dig in a bit more; It appears that it gets stuck in here within: int mbedtls_ctr_drbg_reseed( mbedtls_ctr_drbg_context *ctx, const unsigned char *additional, size_t len ) memset( seed, 0, MBEDTLS_CTR_DRBG_MAX_SEED_INPUT ); printf("(%d) %s: Done\r\n", __LINE__, __FUNCTION__); <---- line#412 /* * Gather entropy_len bytes of entropy to seed state */ if( 0 != ctx->f_entropy( ctx->p_entropy, seed, ctx->entropy_len ) ) <----- appears to be stuck in this callback f_entropy() { return( MBEDTLS_ERR_CTR_DRBG_ENTROPY_SOURCE_FAILED ); } seedlen += ctx->entropy_len; printf("(%d) %s: Done\r\n", __LINE__, __FUNCTION__); <----- line #424 Sprinkling a few prints here and there, it looks thus: (174) tls_init: Initializing (178) tls_init: SSL initialize (181) tls_init: SSL Config initialized (184) tls_init: x509 CRT initialized (187) tls_init: DRBG initialized (190) tls_init: Entropy initialized (95) mbedtls_ctr_drbg_seed_entropy_len: AES initialized (112) mbedtls_ctr_drbg_seed_entropy_len: AES setkey enc (412) mbedtls_ctr_drbg_reseed: Done (1027) mbedtls_hardware_poll: Random Words: 128 Word: 834688558 Someone help ?
