Thomas Huth	b7cbb8741b	crypto: Fix LGPL information in the file headers It's either "GNU Library General Public License version 2" or "GNU Lesser General Public License version 2.1", but there was no "version 2.0" of the "Lesser" license. So assume that version 2.1 is meant here. Signed-off-by: Thomas Huth <thuth@redhat.com> Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>	8 years ago
Daniel P. Berrangé	aa895bd439	crypto: annotate xts_tweak_encdec as inlineable Encouraging the compiler to inline xts_tweak_encdec increases the performance for xts-aes-128 when built with gcrypt: Encrypt: 545 MB/s -> 580 MB/s Decrypt: 568 MB/s -> 602 MB/s Reviewed-by: Alberto Garcia <berto@igalia.com> Signed-off-by: Daniel P.

Daniel P. Berrangé	cc36930e40	crypto: introduce a xts_uint128 data type The new type is designed to allow use of 64-bit arithmetic instead of operating 1-byte at a time. The following patches will use this to improve performance. Reviewed-by: Alberto Garcia <berto@igalia.com> Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>	8 years ago
Daniel P. Berrangé	299ec87838	crypto: remove code duplication in tweak encrypt/decrypt The tweak encrypt/decrypt functions are identical except for the comments, so can be merged. Profiling data shows that the compiler is in fact already merging the two merges in the object files.

Daniel P. Berrange	84f7f180b0	crypto: import an implementation of the XTS cipher mode The XTS (XEX with tweaked-codebook and ciphertext stealing) cipher mode is commonly used in full disk encryption. There is unfortunately no implementation of it in either libgcrypt or nettle, so we need to provide our own. The libtomcrypt project provides a repository of crypto algorithms under a choice of either "public domain" or the "what the fuck public license". So this impl is taken from the libtomcrypt GIT repo and adapted to be compatible with the way we need to call ciphers provided by nettle/gcrypt.
