A certain maximum amount of data can be safely encrypted when
encryption is performed under a single key.  This amount is called
the "key lifetime".  This specification describes a variety of
methods for increasing the lifetime of symmetric keys.  It provides
two types of re-keying mechanisms based on hash functions and block
ciphers that can be used with modes of operations such as CTR, GCM,
CBC, CFB, and OMAC.
