Noteworthy changes in version 1.7.0 (2016-04-15) [C21/A1/R0]
------------------------------------------------
* New algorithms and modes:
- SHA3-224, SHA3-256, SHA3-384, SHA3-512, and MD2 hash algorithms.
- SHAKE128 and SHAKE256 extendable-output hash algorithms.
- ChaCha20 stream cipher.
- Poly1305 message authentication algorithm
- ChaCha20-Poly1305 Authenticated Encryption with Associated Data
mode.
- OCB mode.
- HMAC-MD2 for use by legacy applications.
* New curves for ECC:
- Curve25519.
- sec256k1.
- GOST R 34.10-2001 and GOST R 34.10-2012.
* Performance:
- Improved performance of KDF functions.
- Assembler optimized implementations of Blowfish and Serpent on
ARM.
- Assembler optimized implementation of 3DES on x86.
- Improved AES using the SSSE3 based vector permutation method by
Mike Hamburg.
- AVX/BMI is used for SHA-1 and SHA-256 on x86. This is for SHA-1
about 20% faster than SSSE3 and more than 100% faster than the
generic C implementation.
- 40% speedup for SHA-512 and 72% for SHA-1 on ARM Cortex-A8.
- 60-90% speedup for Whirlpool on x86.
- 300% speedup for RIPE MD-160.
- Up to 11 times speedup for CRC functions on x86.
* Other features:
- Improved ECDSA and FIPS 186-4 compliance.
- Support for Montgomery curves.
- gcry_cipher_set_sbox to tweak S-boxes of the gost28147 cipher
algorithm.
- gcry_mpi_ec_sub to subtract two points on a curve.
- gcry_mpi_ec_decode_point to decode an MPI into a point object.
- Emulation for broken Whirlpool code prior to 1.6.0. [from 1.6.1]
- Flag "pkcs1-raw" to enable PCKS#1 padding with a user supplied
hash part.
- Parameter "saltlen" to set a non-default salt length for RSA PSS.
- A SP800-90A conforming DRNG replaces the former X9.31 alternative
random number generator.
- Map deprecated RSA algo number to the RSA algo number for better
backward compatibility. [from 1.6.2]
- Use ciphertext blinding for Elgamal decryption [CVE-2014-3591].
See http://www.cs.tau.ac.il/~tromer/radioexp/ for details.
[from 1.6.3]
- Fixed data-dependent timing variations in modular exponentiation
[related to CVE-2015-0837, Last-Level Cache Side-Channel Attacks
are Practical]. [from 1.6.3]
- Flag "no-keytest" for ECC key generation. Due to a bug in
the parser that flag will also be accepted but ignored by older
version of Libgcrypt. [from 1.6.4]
- Speed up the random number generator by requiring less extra
seeding. [from 1.6.4]
- Always verify a created RSA signature to avoid private key leaks
due to hardware failures. [from 1.6.4]
- Mitigate side-channel attack on ECDH with Weierstrass curves
[CVE-2015-7511]. See http://www.cs.tau.ac.IL/~tromer/ecdh/ for
details. [from 1.6.5]
* Internal changes:
- Moved locking out to libgpg-error.
- Support of the SYSROOT envvar in the build system.
- Refactor some code.
- The availability of a 64 bit integer type is now mandatory.
* Bug fixes:
- Fixed message digest lookup by OID (regression in 1.6.0).
- Fixed a build problem on NetBSD
- Fixed memory leaks in ECC code.
- Fixed some asm build problems and feature detection bugs.
* Interface changes relative to the 1.6.0 release:
