Member predicate StdlibPrivate::HmacCryptographicOperation::getBlockMode
Gets the block mode used to perform this cryptographic operation.
This predicate is only expected to have a result if two conditions hold:
- The operation is an encryption operation, i.e. the algorithm used is an
EncryptionAlgorithm
, and - The algorithm used is a block cipher (not a stream cipher).
If either of these conditions do not hold, then this predicate should have no result.
