Member Function Documentation

algorithm_identifier()

AlgorithmIdentifier Botan::PK_Ops::Signature::algorithm_identifier ( ) const

virtual

Return an algorithm identifier associated with this signature scheme.

Default implementation throws an exception

Reimplemented in Botan::XMSS_Signature_Operation.

Definition at line 25 of file pk_ops.cpp.

                                                                {
   throw Not_Implemented("This signature scheme does not have an algorithm identifier available");
}

hash_function()

virtual std::string Botan::PK_Ops::Signature::hash_function ( ) const

pure virtual

Return the hash function being used by this signer

Implemented in Botan::PK_Ops::Signature_with_Hash, Botan::TPM2::Signature_Operation_Base< PK_Ops::Signature >, and Botan::XMSS_Signature_Operation.

sign()

virtual std::vector< uint8_t > Botan::PK_Ops::Signature::sign ( RandomNumberGenerator & rng )

pure virtual

Perform a signature operation

Parameters

rng	a random number generator

Implemented in Botan::PK_Ops::Signature_with_Hash, Botan::TPM2::Signature_Operation, and Botan::XMSS_Signature_Operation.

signature_length()

virtual size_t Botan::PK_Ops::Signature::signature_length ( ) const

pure virtual

Return an upper bound on the length of the output signature

Implemented in Botan::XMSS_Signature_Operation.

update()

virtual void Botan::PK_Ops::Signature::update ( std::span< const uint8_t > input )

pure virtual

Add more data to the message currently being signed

Parameters

input

the input to be hashed/signed

Implemented in Botan::PK_Ops::Signature_with_Hash, Botan::TPM2::Signature_Operation_Base< PK_Ops::Signature >, and Botan::XMSS_Signature_Operation.
