Botan/Botan-2.7.0.tgz.asc

Accepting request 621856 from home:dmolkentin:branches:devel:libraries:c_c++ - Update to Botan 2.7 * CVE-2018-12435 Avoid a side channel in ECDSA signature generation (GH #1604) * Avoid a side channel in RSA key generation due to use of a non-constant time gcd algorithm. (GH #1542 #1556) * Optimize prime generation, especially improving RSA key generation. (GH #1542) * Make Karatsuba multiplication, Montgomery field operations, Barrett reduction and Montgomery exponentiation const time (GH #1540 #1606 #1609 #1610) * Optimizations for elliptic curve operations especially improving reductions and inversions modulo NIST primes (GH #1534 #1538 #1545 #1546 #1547 #1550) * Add 24 word wide Comba multiplication, improving 3072-bit RSA and DH by ~25%. (GH #1564) * Unroll Montgomery reduction for specific sizes (GH #1603) * Improved performance of signature verification in ECGDSA, ECKCDSA, SM2 and GOST by 10-15%. * XMSS optimizations (GH #1583 #1585) * Fix an error that meant XMSS would only sign half as many signatures as is allowed (GH #1582) * Add support for base32 encoding/decoding (GH #1541) * Add BMI2 optimized version of SHA-256, 40% faster on Skylake (GH #1584) * Allow the year to be up to 2200 in ASN.1 time objects. Previously this was limited to 2100. (GH #1536) * Add support for Scrypt password hashing (GH #1570) * Add support for using Scrypt for private key encryption (GH #1574) * Optimizations for DES/3DES, approx 50% faster when used in certain modes such as CBC decrypt or CTR. * XMSS signature verification did not check that the signature was of the expected length which could lead to a crash.
