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

Dear Mbed TLS users, We have released Mbed TLS versions 3.6.3 and 2.28.10. These releases provide bugfixes, security fixes and minor improvements. This release of Mbed TLS provides the fix for the TLS compatibility issue of handling fragmented handshake messages. This release includes fixes for security issues. Full details are available in the release notes: https://github.com/Mbed-TLS/mbedtls/releases/tag/mbedtls-2.28.10 https://github.com/Mbed-TLS/mbedtls/releases/tag/mbedtls-3.6.3 We recommend all users to consider whether they are impacted, and to upgrade appropriately.

[Mbed-tls-announce] Announcing Mbed TLS 3.6.3 and 2.28.10

by Gilles Peskine via Mbed-tls-announce

Dear Mbed TLS users, The next release of Mbed TLS (3.6.3 and 2.28.10) is scheduled on Monday 2025-03-24. It will include a security fix for a vulnerability with a high impact to affected applications. Due to the nature of the vulnerability, which involves an insecure default in current versions of Mbed TLS, fixing it may require a small change in application code. We will provide instructions in the release notes. Without this change, affected applications will fail at runtime with Mbed TLS 3.6.3 or 2.28.10. Applications that are currently secure will generally not require any change. We apologize for the inconvenience.

Inquiry about the ECC-160 bit size support in MbedTLS

by Ankita Hatmode

Hi Team, I am working on an embedded security project and exploring ECC support in MbedTLS 3.6.2. I would like to confirm whether the MbedTLS supports ECC-160 i.e. Elliptic Curve Cryptography with a 160 bit key size, in the latest version or any earlier versions. Looking forward to your response.
