2007-10-10[CRYPTO] des: Rename des to des-genericSebastian Siewior1-1011/+0
Loading the crypto algorithm by the alias instead of by module directly has the advantage that all possible implementations of this algorithm are loaded automatically and the crypto API can choose the best one depending on its priority.

2006-09-21[CRYPTO] api: Get rid of flags argument to setkeyHerbert Xu1-2/+4
Now that the tfm is passed directly to setkey instead of the ctx, we no longer need to pass the &tfm->crt_flags pointer. This patch also gets rid of a few unnecessary checks on the key length for ciphers as the cipher layer guarantees that the key length is within the bounds specified by the algorithm. Rather than testing dia_setkey every time, this patch does it only once during crypto_alloc_tfm. The redundant check from crypto_digest_setkey is also removed.

2006-06-26[CRYPTO] all: Pass tfm instead of ctx to algorithmsHerbert Xu1-12/+15
Up until now algorithms have been happy to get a context pointer since they know everything that's in the tfm already (e.g., alignment, block size). However, once we have parameterised algorithms, such information will be specific to each tfm. So the algorithm API needs to be changed to pass the tfm structure instead of the context pointer. This patch is basically a text substitution. The only tricky bit is the assembly routines that need to get the context pointer offset through asm-offsets.h.

2006-01-09[CRYPTO] cipher: Set alignmask for multi-byte loadsHerbert Xu1-0/+1
Many cipher implementations use 4-byte/8-byte loads/stores which require alignment on some architectures. This patch explicitly sets the alignment requirements for them. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2006-01-09[CRYPTO] Use standard byte order macros wherever possibleHerbert Xu1-0/+2
A lot of crypto code needs to read/write a 32-bit/64-bit words in a specific gender. Many of them open code them by reading/writing one byte at a time. This patch converts all the applicable usages over to use the standard byte order macros. This is based on a previous patch by Denis Vlasenko. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2005-07-06[CRYPTO] Add faster DES code from Dag Arne OsvikDag Arne Osvik1-1149/+854
I've made a new implementation of DES to replace the old one in the kernel. It provides faster encryption on all tested processors apart from the original Pentium, and key setup is many times faster.
