Re: [mbed-tls] Query related to ARM - MbedTLS

by Manuel Pegourie-Gonnard

Hi, On those CPUs, the AES implementation in Mbed TLS is pure C, it doesn't use any hand-written assembly. The only platforms where it does so so far are x86-64 (to take advantage of the AES-NI extension if available), and some Via CPUs (x86) that have AES acceleration as well.

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! 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

[Mbed-tls-announce] Mbed TLS: Security Advisory and Release of Mbed TLS 2.24.0, 2.16.8 and 2.7.17

by Janos Follath via Mbed-tls-announce

Mbed TLS Security Advisories have been issued to accompany the release of Mbed TLS versions 2.24.0, 2.16.8 and 2.7.17, which have just been released. These releases of Mbed TLS address several security issues, provide bug fixes, and bring other minor changes. Full details are available in the release notes (https://github.com/ARMmbed/mbedtls/releases/tag/mbedtls-2.24.0, https://github.com/ARMmbed/mbedtls/releases/tag/mbedtls-2.16.8, https://github.com/ARMmbed/mbedtls/releases/tag/mbedtls-2.7.17) and in the 2020-07 security advisories (https://tls.mbed.org/tech-updates/security-advisories) We recommend all users to consider whether they are impacted, and to upgrade appropriately. -- 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

Hi Manu, It looks like you made a mistake on the client side configuring the certificate/private key.
