529 This driver implements a crypto API template that can be
530 instantiated either as an skcipher or as an AEAD (depending on the
531 type of the first template argument), and which defers encryption
532 and decryption requests to the encapsulated cipher after applying
533 ESSIV to the input IV. Note that in the AEAD case, it is assumed
534 that the keys are presented in the same format used by the authenc
535 template, and that the IV appears at the end of the authenticated
536 associated data (AAD) region (which is how dm-crypt uses it.)
