Detailed Description

template<class INTFACE, class KEY_INTFACE>
class DL_SignatureSchemeBase< INTFACE, KEY_INTFACE >

Discrete Log (DL) signature scheme base implementation.

Template Parameters

INTFACE	PK_Signer or PK_Verifier derived class
KEY_INTFACE	DL_Base key base used in the scheme

DL_SignatureSchemeBase provides common functions for signers and verifiers. DL_Base<DL_PrivateKey> is used for signers, and DL_Base<DL_PublicKey> is used for verifiers.

◆ AllowNonrecoverablePart()

template<class INTFACE , class KEY_INTFACE >

bool DL_SignatureSchemeBase< INTFACE, KEY_INTFACE >::AllowNonrecoverablePart ( ) const

inline

◆ IsProbabilistic()

template<class INTFACE , class KEY_INTFACE >

bool DL_SignatureSchemeBase< INTFACE, KEY_INTFACE >::IsProbabilistic ( ) const

inline

Determines if the scheme is probabilistic.

Returns: true if the scheme is probabilistic, false otherwise

◆ MaxRecoverableLength()

template<class INTFACE , class KEY_INTFACE >

size_t DL_SignatureSchemeBase< INTFACE, KEY_INTFACE >::MaxRecoverableLength ( ) const

inline

Provides the maximum recoverable length.

Returns: maximum recoverable length, in bytes

Definition at line 1558 of file pubkey.h.

◆ MaxRecoverableLengthFromSignatureLength()

template<class INTFACE , class KEY_INTFACE >

size_t DL_SignatureSchemeBase< INTFACE, KEY_INTFACE >::MaxRecoverableLengthFromSignatureLength ( size_t signatureLength ) const

inline

Provides the maximum recoverable length.

Parameters

signatureLength the size of the signature

Returns: maximum recoverable length based on signature length, in bytes

this function is not implemented and always returns 0.

◆ RecoverablePartFirst()

template<class INTFACE , class KEY_INTFACE >

bool DL_SignatureSchemeBase< INTFACE, KEY_INTFACE >::RecoverablePartFirst ( ) const

inline

Determines if the scheme allows recoverable part first.

Returns: true if the message encoding allows the recoverable part, false otherwise.
