Member Function Documentation
◆ InputSignature()
template<class T >
|
inlinevirtual |
Input signature into a message accumulator.
- Parameters
-
messageAccumulator a pointer to a PK_MessageAccumulator derived class signature the signature on the message signatureLength the size of the signature
Implements PK_Verifier.
◆ VerifyAndRestart()
template<class T >
|
inlinevirtual |
Check whether messageAccumulator contains a valid signature and message, and restart messageAccumulator.
- Parameters
-
messageAccumulator a reference to a PK_MessageAccumulator derived class
- Returns
- true if the signature is valid, false otherwise
VerifyAndRestart() restarts the messageAccumulator
Implements PK_Verifier.
◆ RecoverAndRestart()
template<class T >
|
inlinevirtual |
Recover a message from its signature.
- Parameters
-
recoveredMessage a pointer to the recoverable message part to be verified messageAccumulator a pointer to a PK_MessageAccumulator derived class
- Returns
- the result of the verification operation
RecoverAndRestart() restarts the messageAccumulator
- Precondition
COUNTOF(recoveredMessage) == MaxRecoverableLengthFromSignatureLength(signatureLength)
Implements PK_Verifier.
