Like Cryptokit.Block.cipher
, but removes padding on the output data as specified by the first argument. The output block size of the returned transform is 1; the input block size is the block size of the block cipher.
Build a MAC (keyed hash function) from the given block cipher. The block cipher is run in CBC mode, and the MAC value is the final value of the initialization vector. Thus, the hash size of the resulting hash is the block size of the block cipher. The optional argument iv
specifies the first initialization vector, with a default of all zeroes. The optional argument pad
specifies a padding scheme to be applied to the input data; if not provided, no padding is performed.
add_substring b pos len
adds len
characters from byte array b
, starting at character number pos
, to the running hash computation.
add_substring b pos len
adds len
characters from byte array b
, starting at character number pos
, to the running hash computation.
add_string str
adds all characters of string str
to the running hash computation.
add_string str
adds all characters of string str
to the running hash computation.
add_char c
adds character c
to the running hash computation.
add_char c
adds character c
to the running hash computation.
add_byte b
adds the character having code b
to the running hash computation. b
must be between 0
and 255
inclusive.
add_byte b
adds the character having code b
to the running hash computation. b
must be between 0
and 255
inclusive.
Terminate the hash computation and return the hash value for the input data provided via the add_*
methods. The hash value is a string of length hash_size
characters. After calling result
, the hash can no longer accept additional data. Hence, do not call any of the add_*
methods after result
.

Return the size of hash values produced by this hash function, in bytes.
