* Import the skein hashing algorithm, based on the threefish block cipherAllan Jude2016-05-291-1/+4
| | | | | | | | | | | | | | | | Connect it to userland (libmd, libcrypt, sbin/md5) and kernel (crypto.ko) Support for skein as a ZFS checksum algorithm was introduced in r289422 but is disconnected because FreeBSD lacked a Skein implementation. A further commit will enable it in ZFS. Reviewed by: cem Sponsored by: ScaleEngine Inc. Differential Revision: https://reviews.freebsd.org/D6166 Notes: svn path=/head/; revision=300921
* Implement SHA-512 truncated (224 and 256 bits)Allan Jude2016-05-281-6/+39
| | | | | | | | | | | | | | | | | | | | | | This implements SHA-512/256, which generates a 256 bit hash by calculating the SHA-512 then truncating the result. A different initial value is used, making the result different from the first 256 bits of the SHA-512 of the same input. SHA-512 is ~50% faster than SHA-256 on 64bit platforms, so the result is a faster 256 bit hash. The main goal of this implementation is to enable support for this faster hashing algorithm in ZFS. The feature was introduced into ZFS in r289422, but is disconnected because SHA-512/256 support was missing. A further commit will enable it in ZFS.
