2008-01-11[CRYPTO] seqiv: Add AEAD supportHerbert Xu1-16/+175
This patch adds support for using seqiv with AEAD algorithms. This is useful for those AEAD algorithms that performs authentication before encryption because the IV generated by the underlying encryption algorithm won't be available for authentication.

2008-01-11[CRYPTO] seqiv: Add Sequence Number IV GeneratorHerbert Xu1-0/+186
This generator generates an IV based on a sequence number by xoring it with a salt. This algorithm is mainly useful for CTR and similar modes. This patch also sets it as the default IV generator for ctr. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
