Public Member Functions | |
const KeyClass & | GetKey () const |
KeyClass & | AccessKey () |
PublicKey & | AccessPublicKey () |
bool | VerifyAndRestart (HashTransformation &messageAccumulator, const byte *sig) const |
check whether sig is a valid signature for messageAccumulator, and restart messageAccumulator | |
bool | SignatureUpfrontForRecovery () const |
HashTransformation * | NewRecoveryAccumulator (const byte *signature) const |
create a new HashTransformation to accumulate leftover message | |
DecodingResult | Recover (byte *recoveredMessage, HashTransformation *recoveryAccumulator, const byte *signature) const |
recover a message from its signature | |
const TrapdoorFunctionBounds & | GetTrapdoorFunctionBounds () const |
unsigned int | SignatureLength () const |
signature length support by this object (as either input or output) | |
HashTransformation * | NewMessageAccumulator () const |
deprecated, please use PK_Signer::NewSignatureAccumulator or PK_Verifier::NewVerificationAccumulator instead | |
unsigned int | MaximumRecoverableLength () const |
length of longest message that can be fully recovered | |
bool | AllowLeftoverMessage () const |
whether or not messages longer than MaximumRecoverableLength() can be signed | |
virtual DecodingResult | RecoverMessage (byte *recoveredMessage, const byte *message, unsigned int messageLen, const byte *signature) const |
recover a message from its signature | |
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 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 | |
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 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 | |

check whether sig is a valid signature for messageAccumulator, and restart messageAccumulator
Implements PK_Verifier. Definition at line 587 of file pubkey.h. References SignatureSystemWithRecoveryBaseTemplate< H >::SignatureLength(), SecBlock< byte >::size(), and HashTransformation::Verify(). |
|
If this function returns true, you must input the signature when calling NewRecoveryAccumulator(). Otherwise, you must input the signature when calling Recover(). Implements PK_VerifierWithRecovery. |
|
recover a message from its signature
Implements PK_VerifierWithRecovery. |
|
whether or not messages longer than MaximumRecoverableLength() can be signed If this function returns false, any message longer than MaximumRecoverableLength() will be truncated for signature and will fail verification. Implements PK_SignatureSchemeWithRecovery. |
