2006-06-26[CRYPTO] all: Pass tfm instead of ctx to algorithmsHerbert Xu
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 Xu
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 Xu
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 Osvik
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.

The iv field in des_ctx/des3_ede_ctx/serpent_ctx has never been used. This was noticed by Dag Arne Osvik. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
