Create a new HashTransformation to accumulate the message to be verified.
- Returns
- a pointer to a PK_MessageAccumulator
NewVerificationAccumulator() can be used with all verification methods. Verify() will automatically delete the accumulator pointer. The caller is responsible for deletion if a method is called that takes a reference.
Implements PK_Verifier.
