[PATCH] crypto: sha*-mb Fix total_len for correct hash when larger than 512MB

Current multi-buffer hash implementations have a restriction on the total length of a hash job to 512MB. Hashing larger buffers will result in an incorrect hash. This extends the limit to 2^62 - 1. Signed-off-by: Greg Tucker --- arch/x86/crypto/sha1-mb/sha1_mb.c | 2 +- arch/x86/crypto/s

[RFC][PATCH 3/7] crypto: gf128mul - Add ble multiplication functions

Adding ble multiplication to GF128mul, and fixing up comments. The ble multiplication functions multiply GF(2^128) elements in the ble format. This format is preferable because the bits within each byte map to polynomial coefficients in the natural order (lowest order bit = coefficient of lowest d

[RFC][PATCH 4/7] crypto: shash - Add crypto_grab_shash() and crypto_spawn_shash_alg()

Analogous to crypto_grab_skcipher() and crypto_spawn_skcipher_alg(), these are useful for algorithms that need to use a shash sub-algorithm, possibly in addition to other sub-algorithms. Signed-off-by: Alex Cope Signed-off-by: Eric Biggers --- crypto/shash.c | 8 includ

[RFC][PATCH 5/7] crypto: heh - Add Hash Encrypt Hash(HEH) algorithm

Hash Encrypt Hash (HEH) is a proposed block cipher mode of operation which extends the strong pseudo-random permutation property of block ciphers (e.g. AES) to arbitrary length input strings. This provides a stronger notion of security than existing block cipher modes of operation (e.g. CBC, CTR, X
