crypto: arc4 - refactor arc4 core code into separate library Refactor the core rc4 handling so we can move most users to a library interface, permitting us to drop the cipher interface entirely in a future patch. This is part of an effort to simplify the crypto API and improve its robustness against incorrect use.

crypto: chacha - move existing library code into lib/crypto Currently, our generic ChaCha implementation consists of a permute function in lib/chacha.c that operates on the 64-byte ChaCha state directly [and which is always included into the core kernel since it is used by the /dev/random driver], and the crypto API plumbing to expose it as a skcipher. In order to support in-kernel users that need the ChaCha streamcipher but have no need [or tolerance] for going through the abstractions of the crypto API, let's expose the streamcipher bits via a library API as well, in a way that permits the implementation to be superseded by an architecture specific one if provided. So move the streamcipher code into a separate module in lib/crypto, and expose the init() and crypt() routines to users of the library.

crypto: aes - create AES library based on the fixed time AES code Take the existing small footprint and mostly time invariant C code and turn it into a AES library that can be used for non-performance critical, casual use of AES, and as a fallback for, e.g., SIMD code that needs a secondary path that can be taken in contexts where the SIMD unit is off limits (e.g., in hard interrupts taken from kernel context) Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: des - split off DES library from generic DES cipher driver Another one for the cipher museum: split off DES core processing into a separate module so other drivers (mostly for crypto accelerators) can reuse the code without pulling in the generic DES cipher itself. This will also permit the cipher interface to be made private to the crypto API itself once we move the only user in the kernel (CIFS) to this library interface.
