Member Function Documentation

virtual secure_vector<byte> Botan::EMSA::encoding_of	(	const secure_vector< 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::EMSA_PKCS1v15_Raw, and Botan::EMSA_PKCS1v15.

virtual secure_vector<byte> Botan::EMSA::raw_data

(

)

[pure virtual]

Returns:

raw hash

Implemented in Botan::EMSA_PKCS1v15_Raw, and Botan::EMSA_PKCS1v15.

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::EMSA_PKCS1v15_Raw, and Botan::EMSA_PKCS1v15.

virtual bool Botan::EMSA::verify	(	const secure_vector< byte > &	coded,
		const secure_vector< 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::EMSA_PKCS1v15_Raw, and Botan::EMSA_PKCS1v15.
