Public Member Functions | |
virtual bool | SignatureUpfrontForVerification () const |
virtual HashTransformation * | NewVerificationAccumulator (const byte *signature=NULL) const |
create a new HashTransformation to accumulate the message to be verified | |
virtual bool | Verify (HashTransformation *messageAccumulator, const byte *signature=NULL) const |
check whether sig is a valid signature for messageAccumulator, and delete messageAccumulator (even in case of exception thrown) | |
virtual bool | VerifyAndRestart (HashTransformation &messageAccumulator, const byte *signature) const=0 |
check whether sig is a valid signature for messageAccumulator, and restart messageAccumulator | |
virtual void | InitializeVerificationAccumulator (HashTransformation &messageAccumulator, const byte *signature) const |
only useful if SignatureUpfrontForVerification() == true | |
virtual bool | VerifyMessage (const byte *message, unsigned int messageLen, const byte *signature) const |
check whether sig is a valid signature for message | |
virtual unsigned int | SignatureLength () const=0 |
signature length support by this object (as either input or output) | |
virtual HashTransformation * | NewMessageAccumulator () const=0 |
deprecated, please use PK_Signer::NewSignatureAccumulator or PK_Verifier::NewVerificationAccumulator instead | |
CryptoMaterial & | AccessMaterial () |
returns a reference to the crypto material used by this object | |
const CryptoMaterial & | GetMaterial () const |
returns a const reference to the crypto material used by this object | |
virtual PublicKey & | AccessPublicKey ()=0 |
virtual const PublicKey & | GetPublicKey () const |
void | BERDecode (BufferedTransformation &bt) |
for backwards compatibility, calls AccessMaterial().Load(bt) | |
void | DEREncode (BufferedTransformation &bt) const |
for backwards compatibility, calls GetMaterial().Save(bt) | |
virtual std::string | AlgorithmName () const |
returns name of this algorithm, not universally implemented yet | |
virtual Clonable * | Clone () const |
this is not implemented by most classes yet |
|
If this function returns true, you must input the signature when calling NewVerificationAccumulator(). Otherwise, you must input the signature when calling Verify(). Definition at line 1268 of file cryptlib.h. |
