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