-Cipher Definition With struct blkcipher_alg and ablkcipher_alg
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Cipher Definition With struct skcipher_alg
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Struct blkcipher_alg defines a synchronous block cipher whereas struct
-ablkcipher_alg defines an asynchronous block cipher.
+Struct skcipher_alg defines a multi-block cipher, or more generally, a
+length-preserving symmetric cipher algorithm.
-Please refer to the single block cipher description for schematics of
-the block cipher usage.
+Scatterlist handling

-Specifics Of Asynchronous Multi-Block Cipher
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-There are a couple of specifics to the asynchronous interface.
-
-First of all, some of the drivers will want to use the Generic
-ScatterWalk in case the hardware needs to be fed separate chunks of the
-scatterlist which contains the plaintext and will contain the
-ciphertext. Please refer to the ScatterWalk interface offered by the
-Linux kernel scatter / gather list implementation.
