| (I) A set of cryptographic algorithms together with the key
management processes that support use of the algorithms in some
application context.
(C) This "I" definition covers a wider range of algorithms than
the following "O" definition:
(O) "A collection of transformations from plaintext into
ciphertext and vice versa [which would exclude digital signature,
cryptographic hash, and key agreement algorithms], the particular
transformation(s) to be used being selected by keys. The
transformations are normally defined by a mathematical algorithm."
