Botan C++ Crypto Algorithms Library 3.3.0
Posted Feb 21, 2024
Site botan.randombit.net

Botan is a C++ library of cryptographic algorithms, including AES, DES, SHA-1, RSA, DSA, Diffie-Hellman, and many others. It also supports X.509 certificates and CRLs, and PKCS #10 certificate requests, and has a high level filter/pipe message processing system. The library is easily portable to most systems and compilers, and includes a substantial tutorial and API reference. This is the current 3.x.x release.

Changes: Fixed a potential denial of service caused by accepting arbitrary length primes as potential elliptic curve parameters in ASN.1 encodings. Added FrodoKEM post-quantum KEM. Added support for Blake2s. Added support for RFC 7250 in TLS 1.3 to allow authenticating peers using raw public keys. 43 additional changes and additions.

Changes: Fixed a potential denial of service caused by accepting arbitrary length primes as potential elliptic curve parameters in ASN.1 encodings. Switched to using a constant time binary algorithm for computing GCD . Fixed a bug in SHAKE_Cipher which could cause incorrect output if set_key was called multiple times. Fixed a bug in RSA-KEM encryption where the shared secret key was incorrectly not padded to exactly the byte length of the modulus. 8 additional fixes and additions.

GNU Transport Layer Security Library 3.8.3
Posted Jan 16, 2024
Authored by Simon Josefsson, Nikos Mavrogiannopoulos | Site gnu.org

GnuTLS is a secure communications library implementing the SSL and TLS protocols and technologies around them. It provides a simple C language application programming interface (API) to access the secure communications protocols, as well as APIs to parse and write X.509, PKCS #12, OpenPGP, and other required structures. It is intended to be portable and efficient with a focus on security and interoperability.

Changes: libgnutls had multiple security fixes. They fixed more timing side-channel issues inside RSA-PSK key exchange. They fixed an assertion failure when verifying a certificate chain with a cycle of cross signatures. Fixed a regression in handling Ed25519 keys stored in PKCS#11 token certtool that was unable to handle Ed25519 keys generated on PKCS#11 with pkcs11-tool (OpenSC). This is a regression introduced in 3.8.2.
