Public Member Functions | |
virtual PK_MessageAccumulator * | NewSignatureAccumulator (RandomNumberGenerator &rng=NullRNG()) const =0 |
create a new HashTransformation to accumulate the message to be signed | |
virtual void | InputRecoverableMessage (PK_MessageAccumulator &messageAccumulator, const byte *recoverableMessage, unsigned int recoverableMessageLength) const =0 |
virtual unsigned int | Sign (RandomNumberGenerator &rng, PK_MessageAccumulator *messageAccumulator, byte *signature) const |
sign and delete messageAccumulator (even in case of exception thrown) | |
virtual unsigned int | SignAndRestart (RandomNumberGenerator &rng, PK_MessageAccumulator &messageAccumulator, byte *signature, bool restart=true) const =0 |
sign and restart messageAccumulator | |
virtual unsigned int | SignMessage (RandomNumberGenerator &rng, const byte *message, unsigned int messageLen, byte *signature) const |
sign a message | |
virtual unsigned int | SignMessageWithRecovery (RandomNumberGenerator &rng, const byte *recoverableMessage, unsigned int recoverableMessageLength, const byte *nonrecoverableMessage, unsigned int nonrecoverableMessageLength, byte *signature) const |
sign a recoverable message | |
virtual unsigned int | SignatureLength () const =0 |
signature length if it only depends on the key, otherwise 0 | |
virtual unsigned int | MaxSignatureLength (unsigned int recoverablePartLength=0) const |
maximum signature length produced for a given length of recoverable message part | |
virtual unsigned int | MaxRecoverableLength () const =0 |
length of longest message that can be recovered, or 0 if this signature scheme does not support message recovery | |
virtual unsigned int | MaxRecoverableLengthFromSignatureLength (unsigned int signatureLength) const =0 |
length of longest message that can be recovered from a signature of given length, or 0 if this signature scheme does not support message recovery | |
virtual bool | IsProbabilistic () const =0 |
requires a random number generator to sign | |
virtual bool | AllowNonrecoverablePart () const =0 |
whether or not a non-recoverable message part can be signed | |
virtual bool | SignatureUpfront () const |
if this function returns true, during verification you must input the signature before the message, otherwise you can input it at anytime */ | |
virtual bool | RecoverablePartFirst () const =0 |
whether you must input the recoverable part before the non-recoverable part during signing | |
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 PrivateKey & | AccessPrivateKey ()=0 |
virtual const PrivateKey & | GetPrivateKey () 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 |
