Question about using hardware-backed parameters in ALT crypto implementations

by Massimiliano Cialdi

Hi, I’m working with Mbed TLS 2.28.x on a microcontroller that provides a built-in crypto engine. The existing *_ALT support works fine for performance, and higher-level modules correctly route their block operations through the accelerated backend. On this platform the crypto hardware can also use internal key material stored in dedicated slots. These values are not accessible as byte arrays and cannot be passed to the usual setkey_*() API. Question Is there a recommended way to configure an ALT implementation so that it can select an internal key slot instead of receiving a buffer? Or, more generally, how should an ALT backend represent a key that is not exposed to software? Any guidance on the intended design would be appreciated. Thanks!

Security backports for v2.28

by Matt Bauman

Hello all, I know that v2.28.10 is EOL, but I've been working on bringing security bug fixes to our distribution of it as part of my work in shoring up the Julia package ecosystem. I've largely leaned on the Debian security team's work thus far; they have the much harder task of supporting 2.16.9 for bullseye (security) and have done great work in bringing that version up to date through CVE-2025-52497. I've re-landed their backport patches against v2.28.10; these can be found on our build tree [1] or my fork [2]: 1. https://github.com/JuliaPackaging/Yggdrasil/tree/54c5a3e8e72899a3a778d8617f… 2. https://github.com/Mbed-TLS/mbedtls/compare/v2.28.10...mbauman:mbedtls:v2.2… Now I'm faced with the daunting prospect of last week's CVE-2025-54764 and CVE-2025-59438. These are *much* larger changesets. Has anyone else begun tackling this? I very much appreciated the guidance that’s included in the advisory itself, but I'm guessing there may be others in our situation... and I came here looking to see if anyone had begun talking about this (or working on it) yet. Best, Matt

Modernizing a ecdh exchange

by Dirk-Willem van Gulik

I am currently doing an ECDH exchange over MQTT (i.e. at the message layer; MQTT is fundamentally `untrusted') - with a bit of out of band work to confirm end to end integrity. That worked nicely (and interoperable with java-bouncy-castle and openssl, etc with: mbedtls_ecp_group_load( &ctx_cli.grp, MBEDTLS_ECP_DP_CURVE25519 ) mbedtls_ecdh_gen_public( &ctx_cli.grp, &ctx_cli.d, &ctx_cli.Q, mbedtls_ctr_drbg_random, &ctr_drbg) mbedtls_mpi_write_binary( &ctx_cli.Q.X, node_publicsession, 32 ) to create the keys and with mbedtls_mpi_lset( &ctx_cli.private_Qp.Z, 1 )) mbedtls_mpi_read_binary( &ctx_cli.private_Qp.X, pubencr_tmp, CURVE259919_KEYLEN)) mbedtls_ecdh_compute_shared( &ctx_cli.grp, &ctx_cli.private_z, &ctx_cli.private_Qp, &ctx_cli.private_d, mbedtls_ctr_drbg_random, &ctr_drbg ) mbedtls_mpi_write_binary( &ctx_cli.private_z, sessionkey, CURVE259919_KEYLEN) to calculate the emphemeral session key. With the mbedtls_ecdh_context going increasingly private; I assume I can change the latter with: mbedtls_ecdh_calc_secret(&ctx_cli, &len_sessionkey, sessionkey, sizeof(sessionkey), mbedtls_ctr_drbg_random, &ctr_drbg) but am struggling to see how I an replace the key generation itself. Is there a similar option that does not look `into' ctx_cli ?? With kind regards, Dw. PS: actual code at https://github.com/MakerSpaceLeiden/AccesSystem/blob/master/lib-arduino/ACN…

DTLS handshake with and without hello verify request

by Ankita Hatmode

Hi Team, I am working on exploring DTLS handshake using the mbedtls-3.6.4 version on our embedded platform. I enabled the hello verify request feature and got stuck at hello verify request state on server side if I don't reset the ssl context and don't set the client transport ID. I want to know if there is any way to complete a handshake by bypassing the reset of ssl context and setting the client transport ID. Also, our environment only supports C89 constructs. I could not see inttypes.h in the mbedtls-3.6.4, is there any specific reason to remove this file? I am getting compilation errors without inttypes.h and stdint.h. Is there any macro to be enabled to support the c89 compilation in mbedtls stack? Looking forward to your response.

TLS 1.3 and brainpool curves

by Maren Konrad

Dear MbedTLS maintainers, we are already using MBedTLS, however, we recently enabled TLS 1.3 and found that our certificates doesn't work anymore, because they are brainpoolP256r1 (https://datatracker.ietf.org/doc/html/rfc8734). So the question would be, if I missed any configuration to enable the usage of brainpool curves (which are working for TLS 1.2) or if there are any plans, that these are getting supported by MBedTLS 3.6.x? Best regards, Maren Konrad

TLS handshake error : unexpected eof

We get below error 20E094B0FFFF0000:error:0A000126:SSL routines:ssl3_read_n:unexpected eof while reading:/usr/src/debug/openssl/3.1.0-r0/ssl/record/rec_layer_s3.c:303: # openssl s_client -connect 192.168.142.1:7001 -no_tls1_3 fails After seeing the trace we have enabled ciphers but still we see the issue. please advise, thanks.

Credential validation BEFORE first TLS handshake: the present and future of mbedtls_pk_sign/verify()

by Almut Herzog

Hi, Prior to the first TLS handshake our application is required to perform input validation of the provided credentials (from file or smart card) for this peer. One of those checks is to verify that private and public key match. We used to use mbedtls_pk_sign() with a custom mbedtls_pk_context for that. But in version 3.X mbedtls_pk_info_t was made private so mbedtls_pk_setup() with a custom mbedtls_pk_info_t whose sign_func would call into our smart card wrapper is no longer possible. Is there still a way to provide custom callback functions for signing in 3.6.4 somehow? Or any other workaround for early check of a key pair? Looking at 4.0.0-beta, also pk.h is no longer public. Will it still be possible to perform early validation of this peer's credentials prior to a first TLS handshake? How? While I am at it, it would be good to implement something that is future-proof. What else I have looked at: * mbedtls_pk_setup_opaque() might be the way to go but I do not find an example of how to link a key id to a custom signature function. * mbedtls_pk_setup_rsa_alt() would be useful if our application was always using RSA. * Both functions are no longer public in 4.0 Related: Early validation of a CRL (whether it was signed by the expected CA) used to be possible with mbedtls_pk_verify_ext(). But to properly set the input parameters requires access to private members of mbedtls_x509_crl in 3.6.4 (maybe an acceptable move?) but in 4.0.0 mbedtls_pk_verify_ext() is no longer public. How perform explicit/"manual" CRL validation especially given the possibly skipped CRL validation in mbedtls_x509_crt_verify() as per the comment below? "It is your responsibility to provide up-to-date CRLs for all trusted CAs. If no CRL is provided for the CA that was used t sign the certificate, CRL verification is skipped silently..." Any future-proof ideas for this? Best regards, /Almut

Mbed TLS 4.0.0-beta & TF-PSA-Crypto 1.0.0-beta releases.

by Minos Galanakis

I am happy to announce the joint-release of Mbed TLS 4.0.0-beta & TF-PSA-Crypto 1.0.0-beta PSA-Crypto now lives in its own repository while TLS and X.509 remain in Mbed TLS. This beta release breaks compatibility with earlier versions of Mbed TLS. Please do not use it in production. It’s intended for the community to verify codebase integrations against the split and API changes, and for early adopters to experiment and provide feedback. For full details, please see the release pages: Mbed TLS 4.0.0-beta: https://github.com/Mbed-TLS/mbedtls/releases/tag/mbedtls-4.0.0-beta TF-PSA-Crypto 1.0.0-beta: https://github.com/Mbed-TLS/TF-PSA-Crypto/releases/tag/tf-psa-crypto-1.0.0-…

imx-secure-enclave with mbedtls 2.28.9

by kavitha bk

Hi We are using mbedtls 2.28.9 and want to offload crypto operations to HSM from NXP imx-secure-enclave. is the below approach correct or please suggest alternate approaches if any? 1.Transition all apis from traditional apis to psa in modules Use PSA crypto module https://github.com/Mbed-TLS/mbedtls/blob/development/docs/psa-transition.md 2. Integrate PSA module with imx-secure-enclave in our custom mbedtls 3. All modules will use custom mbedtls which will internally offload crypto operations to HSM or Do you recommend to use MBEDTLS_PK_RSA_ALT_SUPPORT? and implement the key creation/signing/export of public key operations ? Thanks, Kavitha
