------------------------------------------------------------------------------- - Fedora Update Notification FEDORA-2018-98ab6b4e56 2018-07-11 19:27:57.419836 ------------------------------------------------------------------------------- -
Name : botan2 Product : Fedora 27 Version : 2.7.0 Release : 1.fc27 URL : https://botan.randombit.net/ Summary : Crypto and TLS for C++11 Description : Botan is a BSD-licensed crypto library written in C++. It provides a wide variety of basic cryptographic algorithms, X.509 certificates and CRLs, PKCS \#10 certificate requests, a filter/pipe message processing system, and a wide variety of other features, all written in portable C++. The API reference, tutorial, and examples may help impart the flavor of the library. This is the current stable release branch 2.x of Botan.
------------------------------------------------------------------------------- - Update Information:
Update Botan2 to 2.7.0. Focus of this release is on performance and side channel hardening. - Address side channels in RSA key generation and ECDSA signing - Side channel hardening in many core algorithms (modular exponentiation, ECC scalar multiply, Karatsuba multiplication, Barrett reduction, etc) to reduce the risk of future exploitable side channels. - Many optimizations for ECC operations, RSA (including key gen), DSA, DH, and XMSS. Typical speedups vs 2.6.0 is 10 to 40% depending on operation and key size. - Add Scrypt password hashing. Also supported is using Scrypt to derive keys for private key encryption (format compatible with upcoming OpenSSL 1.1.1) - Add base32 encoding/decoding - Plus many bug fixes and smaller enhancements documented in the [release notes](https://botan.randombit.net/news.html#version-2-7-0-2018-07-02) ------------------------------------------------------------------------------- - References:
