| | | | | | | | Flag all GHASH ARMv8 vmull.p64 helper ciphers as internal ciphers to prevent them from being called by normal users. Signed-off-by: Stephan Mueller <smueller@chronox.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: arm - add support for GHASH using ARMv8 Crypto ExtensionsArd Biesheuvel2015-03-121-0/+318
This implements the GHASH hash algorithm (as used by the GCM AEAD chaining mode) using the AArch32 version of the 64x64 to 128 bit polynomial multiplication instruction (vmull.p64) that is part of the ARMv8 Crypto Extensions.
