/*
- * AEAD memory structure: For encryption, the tag is appended to the
- * ciphertext which implies that the memory allocated for the ciphertext
- * must be increased by the tag length. For decryption, the tag
- * is expected to be concatenated to the ciphertext. The plaintext
- * therefore has a memory size of the ciphertext minus the tag length.
- *
- * The memory structure for cipher operation has the following
- * structure:
- * AEAD encryption input: assoc data || plaintext
- * AEAD encryption output: cipherntext || auth tag
- * AEAD decryption input: assoc data || ciphertext || auth tag
- * AEAD decryption output: plaintext
+ * Please see documentation of aead_request_set_crypt for the
+ * description of the AEAD memory structure expected from the caller.
