(cipher/clear cipher-obj)Reset the state of `cipher` back to clean, as if no key and input has been supplied. Returns `cipher-obj`.
(cipher/finish cipher-obj input)Finish processing (with an optional final `input`). May throw if message authentication checks fail, in which case all plaintext previously processed must be discarded. You may call `cipher/finish` with the entire message.
(cipher/get-default-nonce-length cipher-obj)Returns default nonce length.
(cipher/get-keyspec cipher-obj)Return the key spec of this `cipher` in format of `[max-key-length min-key-length mod-key-length]`.
(cipher/get-tag-length cipher-obj)Returns the tag length (0 for unauthenticated modes).
(cipher/get-update-granularity cipher-obj)Return the update granularity of the cipher. `cipher/update` must be called with blocks of this size, except for the final.
(cipher/is-authenticated cipher-obj)Returns true if this is an AEAD mode.
(cipher/new name type)Creates an cipher object of the given name, e.g., "AES-256/GCM".Create an encryption cipher if `:encrypt` type is given, create decryption cipher if `:decrypt` type is supplied.
(cipher/set-associated-data cipher-obj ad)Sets the associated data and returns `cipher-obj`. Fails if this is not an AEAD mode.
(cipher/set-key cipher-obj key)Set the symmetric key to be used. Returns `cipher-obj`.
(cipher/start cipher-obj nonce)Start processing a message using `nonce`. Returns `cipher-obj`.
(cipher/update cipher-obj input)Consumes `input` text and returns output. Input text must be of `cipher/get-update-granularity` length. Alternately, always call finish with the entire message, avoiding calls to update entirely.
(cipher/valid-nonce-length cipher-obj nonce-len)Returns true if `nonce-len` is a valid nonce len for this mode.
