     86  *     SUBNAME may be present where we are combining multiple
     87  *     algorithms together, e.g. MD5-SHA1.
     88  *
     89  *     SIZE is only present if multiple versions of an algorithm exist
     90  *     with different sizes (e.g. AES-128-CBC, AES-256-CBC)
     91  *
     92  *     MODE is only present where applicable.
