Member Function Documentation

encoding_of()

virtual SecureVector< byte > Botan::EMSA::encoding_of ( const MemoryRegion< byte > & msg, size_t output_bits, RandomNumberGenerator & rng )

pure virtual

Return the encoding of a message

Parameters

msg	the result of raw_data()
output_bits	the desired output bit size
rng	a random number generator

Returns

encoded signature

Implemented in Botan::EMSA3, and Botan::EMSA3_Raw.

raw_data()

virtual SecureVector< byte > Botan::EMSA::raw_data ( )

pure virtual

Returns

raw hash

Implemented in Botan::EMSA3, and Botan::EMSA3_Raw.

update()

virtual void Botan::EMSA::update ( const byte input[], size_t length )

pure virtual

Add more data to the signature computation

Parameters

input	some data
length	length of input in bytes

Implemented in Botan::EMSA3, and Botan::EMSA3_Raw.

verify()

virtual bool Botan::EMSA::verify ( const MemoryRegion< byte > & coded, const MemoryRegion< byte > & raw, size_t key_bits )

pure virtual

Verify the encoding

Parameters

coded	the received (coded) message representative
raw	the computed (local, uncoded) message representative
key_bits	the size of the key in bits

Returns

true if coded is a valid encoding of raw, otherwise false

Implemented in Botan::EMSA3, and Botan::EMSA3_Raw.
