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! Best regards, Janos (On behalf of the Mbed TLS team) -- Mbed-tls-announce mailing list Mbed-tls-announce(a)lists.trustedfirmware.org https://lists.trustedfirmware.org/mailman/listinfo/mbed-tls-announce

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] mbedtls handshake failed

by Hannes Tschofenig

Hi Manu, It looks like you made a mistake on the client side configuring the certificate/private key. The client does not send the certificate and that corresponds to the error message on the server-side ("peer did not return a certificate"). Ciao Hannes -----Original Message----- From: mbed-tls <mbed-tls-bounces(a)lists.trustedfirmware.org> On Behalf Of Manu Abraham via mbed-tls Sent: Tuesday, August 25, 2020 5:20 PM To: mbed-tls(a)lists.trustedfirmware.org Subject: [mbed-tls] mbedtls handshake failed 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.

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

by Dan Handley

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.

Re: [mbed-tls] LTS roadmap and announcement channel?

by Manuel Pegourie-Gonnard

Hi Simon, Indeed while the migration is underway things can be a bit confusing, so let me try to clarify: * releases can be found at: https://github.com/ARMmbed/mbedtls/releases - near the top you'll alwys find the latest development release followed by the latest LTS releases. At this point it is unclear if releases are going to stay on github or if they would move to trustedfrimware.org in the future, but if anything changes, we'll announce it. * announcements about new releases and other important project events are made on the new Mbed-tls-announce mailing-list: https://github.com/ARMmbed/mbedtls/releases - if you're already subscribed to mbed-tls (this list), you don't need to subscribe to the "announce" mailing list in addition, as any post to "announce" is automatically cross-posted here ("announce" is for people who want a lower volume list). * I don't think we're currently making announcements about upcoming releases, but I know we considered that. Unfortunately I don't remember the details and the colleague who was working on improving our release process is on leave now. But it we start making such announcements, they'll be on the "announce" list. * We're currently planning 2.16.8 early in September. * If you have a large number of products deployed that depend on Mbed TLS (or indeed any other tf.org project) and would like to be notified in advance of upcoming security fixes, please see the following pages: https://developer.trustedfirmware.org/w/mbed-tls/security-center/ https://developer.trustedfirmware.org/w/collaboration/security_center/repor… https://developer.trustedfirmware.org/w/collaboration/security_center/trust… I hope this answers your questions, and feel free to ask otherwise.

MbedTLS_hardware_poll

by youssouf sokhona

Hi everyone, Hope you are still going well I am now working on MbedTLS to establish a key exchange with a BGM which has a TRNG , and I read that I have to implement myself a function called «mbedTLS_hardware_poll » But I have no idea to know how I can implement this function zlthough I read articles on the mbedtls.com about entropy site…. Can you help me, to know how I can implement this function ?

Custom PSA API Implementation for mbedTLS tests

by murat＠za-ya.co

Hi all, We have implemented the PSA Functional API for a custom secure environment which passes PSA Arch tests. 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] Diffie Hellman Key Exchange

Hello, The interface of the Diffie-Hellman (DHM) module is modeled on the way it's used in TLS, which is a bit different from the classical presentation. You can find code examples in programs/pkey/dh_client.c and programs/pkey/dh_server.c . Elliptic-curve Diffie-Hellman (provided by the ECDH module) has similar security properties and is significantly faster. If you don't need interoperability with legacy software that only supports classical (finite-field) Diffie-Hellman, you should use ECDH rather than DHM. With the ECDH module, you can use either the same TLS-inspired interface as the DHM module, or a more classical interface for which there is a usage example in psa_crypto.c in the function psa_key_agreement_ecdh. Hope this helps, -- Gilles Peskine Mbed TLS developer You can find an example of the TLS-like inter On 12/08/2020 14:02, youssouf sokhona via mbed-tls wrote: > > Hello, I hope you are going well during this Covid crisis. > > > > I'm sending you this message to find out how to generate a Diffie > Hellman key using MbedTLS.

Minimum Python version

by Gilles Peskine

Hello, Short version: to use the official tools to configure Mbed TLS, or to run the unit tests, you need Python. If we start requiring Python 3.5, is this going to be a problem? Detailed version: Mbed TLS includes four Python scripts that are of interest to users, with a fifth one in preparation: * scripts/config.py : compile-time configuration (unless you prefer to edit config.h directly). * scripts/generate_psa_constants.py : to build programs/psa/psa_constant_names (we have a pending task to commit the result instead of requiring it during the build). * tests/scripts/generate_test_code.py : necessary to build the unit tests. * tests/scripts/mbedtls_test.py : does anyone use this? It's for testing on platforms with Greentea, but some of the automation is missing. * upcoming: a script to generate glue code for accelerator and secure element drivers. We'll also provide a manual way, but it won't be as convenient. This is a question to everyone who's building Mbed TLS and using some of these scripts: is it ok if they require Python 3.5? Currently: * scripts/config.py requires Python 3.5. * scripts/generate_psa_constants.py requires Python 3.3. * tests/scripts/generate_test_code.py still works with Python 2.7. * tests/scripts/mbedtls_test.py still works with Python 2.7. * the driver glue code generation script will require Python 3.5, or Python 3.4 + typing. Is there any demand for versions of Python before 3.5? -- Gilles Peskine Mbed TLS developer

Diffie Hellman Key Exchange

by youssouf sokhona

Hello, I hope you are going well during this Covid crisis. I'm sending you this message to find out how to generate a Diffie Hellman key using MbedTLS. Indeed, with all the documentation, I'm a bit lost. I think, you have to use the int mbedtls_dhm_set_group function to create p and g. And then, I don't know how to use which function... Moreover, I can't find any function that allows to set a and b, whereas they are 2 fundamental elements Can you help me? Thank you! Best regards, YS

Re: [mbed-tls] Availability of 2.16.7 in download archive

by Janos Follath

Hi Frank, We have now updated the links both on the download-archive and releases site and now they point to https://github.com/ARMmbed/mbedtls/releases, where all the releases are available. We also have added checksums to the release notes on github and fixed the archive structure. Thank you very much for pointing these issues out!

Re: [mbed-tls] Availability of 2.16.7 in download archive

by Gilles Peskine

Hi Frank, I confirm that 2.16.7 is an official release of the 2.16 long-time support branch of Mbed TLS, alongside 2.7.16 for the 2.7 branch and 2.23.0 for the latest features. Everyone should update to one of these versions since they fix security issues and other bugs. We're progressively transitioning the project from Arm infrastructure to TrustedFirmware infrastructure. Eventually we'll decommission the existing tls.mbed.org, and we intend to distribute releases via trustedfirmware.org. We no longer intend to reference new releases directly on https://tls.mbed.org/download-archive . For the time being, we're distributing via GitHub. However, it isn't right that https://tls.mbed.org/download-archive links to https://github.com/ARMmbed/mbedtls/releases/ which doesn't list LTS branches. We need to link from https://tls.mbed.org/download-archive to the place that has the latest LTS releases one way or the other. There are no longer separate archives with Apache and GPL licenses. These archives were always identical except for license headers. Now LTS releases are distributed as a single archive in which the files are dual-licensed. The naming with mbedtls-mbedtls- must be a bug in our release script. Thanks for noticing. I don't think we made a conscious decision not to provide official checksums. I can see the value of having them so let's try to incorporate those in our new release process. -- Gilles Peskine Mbed TLS developer On 04/08/2020 19:05, Frank Bergmann via mbed-tls wrote: > Hi, > > 2.16.7 was released on github more than one month ago (2020-07-01). > But it is not listed on > - download archive at https://tls.mbed.org/download-archive > - release news at https://tls.mbed.org/tech-updates/releases > > Questions about that: > - Is it an "official" release even if it is not mentioned on release news? > - When will it be available in download archive? > - If there will be no more addings to download archive because now we'll > have to use github: > * Will there be separate releases GPL/Apache available? > * Will a signed/unsigned check sum be provided? > * Will the "new structure" as provided by tarball on github be kept > in future or was it just an accident?
