Botan C++ Crypto Algorithms Library 2.16.0

Posted Oct 6, 2020

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 stable release.

Changes: Now userspace PRNG objects (such as AutoSeeded_RNG and HMAC_DRBG) use an internal lock, which allows safe concurrent use. This however is purely a precaution in case of accidental sharing of such RNG objects; for performance reasons it is always preferable to use a RNG per thread if a userspace RNG is needed. DL_Group and EC_Group objects now track if they were created from a known trusted group (such as P-256 or an IPsec DH parameter). If so, then verification tests can be relaxed, as compared to parameters which may have been maliciously constructed in order to pass primality checks. Various other additions and updates.
