[CRYPTO] skcipher: Create default givcipher instances

2008-01-10T21:16:46+00:00

This patch makes crypto_alloc_ablkcipher/crypto_grab_skcipher always
return algorithms that are capable of generating their own IVs through
givencrypt and givdecrypt.  Each algorithm may specify its default IV
generator through the geniv field.

For algorithms that do not set the geniv field, the blkcipher layer will
pick a default.  Currently it's chainiv for synchronous algorithms and
eseqiv for asynchronous algorithms.  Note that if these wrappers do not
work on an algorithm then that algorithm must specify its own geniv or
it can't be used at all.

[CRYPTO] scatterwalk: Move scatterwalk.h to linux/crypto

2008-01-10T21:16:32+00:00

The scatterwalk infrastructure is used by algorithms so it needs to
move out of crypto for future users that may live in drivers/crypto
or asm/*/crypto.

[CRYPTO] api: Kill crypto_km_types

2007-10-10T23:55:44+00:00

When scatterwalk is built as a module digest.c was broken because it
requires the crypto_km_types structure which is in scatterwalk.  This
patch removes the crypto_km_types structure by encoding the logic into
crypto_kmap_type directly.

In fact, this even saves a few bytes of code (not to mention the data
structure itself) on i386 which is about the only place where it's
needed.

[CRYPTO] api: Allow multiple frontends per backend

2007-02-06T22:21:01+00:00

This patch adds support for multiple frontend types for each backend
algorithm by passing the type and mask through to the backend type
init function.

[CRYPTO] digest: Remove old HMAC implementation

2006-09-21T01:46:20+00:00

This patch removes the old HMAC implementation now that nobody uses it
anymore.

[CRYPTO] cipher: Added block ciphers for CBC/ECB

2006-09-21T01:44:08+00:00

This patch adds two block cipher algorithms, CBC and ECB.  These
are implemented as templates on top of existing single-block cipher
algorithms.  They invoke the single-block cipher through the new
encrypt_one/decrypt_one interface.

This also optimises the in-place encryption and decryption to remove
the cost of an IV copy each round.

[CRYPTO] api: Feed flag directly to crypto_yield

2006-09-21T01:41:50+00:00

The sleeping flag used to determine whether crypto_yield can actually
yield is really a per-operation flag rather than a per-tfm flag.  This
patch changes crypto_yield to take a flag directly so that we can start
using a per-operation flag instead the tfm flag.

[CRYPTO] digest: Store temporary digest in tfm

2006-09-21T01:41:02+00:00

When the final result location is unaligned, we store the digest in a
temporary buffer before copying it to the final location.  Currently
that buffer sits on the stack.  This patch moves it to an area in the
tfm, just like the CBC IV buffer.
