Detailed Description

EMSA_PKCS1v15_Raw which is EMSA_PKCS1v15 without a hash or digest id (which according to QCA docs is "identical to PKCS#11's CKM_RSA_PKCS mechanism", something I have not confirmed)

Member Function Documentation

secure_vector< byte > Botan::EMSA_PKCS1v15_Raw::encoding_of	(	const secure_vector< byte > &	msg,
		size_t	output_bits,
		RandomNumberGenerator &	rng
	)		[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

Implements Botan::EMSA.

Definition at line 109 of file emsa_pkcs1.cpp.

   {
   return emsa3_encoding(msg, output_bits, nullptr, 0);
   }

secure_vector< byte > Botan::EMSA_PKCS1v15_Raw::raw_data

(

)

[virtual]

Returns:

raw hash

Implements Botan::EMSA.

Definition at line 101 of file emsa_pkcs1.cpp.

   {
   secure_vector<byte> ret;
   std::swap(ret, message);
   return ret;
   }

void Botan::EMSA_PKCS1v15_Raw::update	(	const byte	input[],
		size_t	length
	)		[virtual]

Add more data to the signature computation

Parameters:

input	some data
length	length of input in bytes

Implements Botan::EMSA.

Definition at line 96 of file emsa_pkcs1.cpp.

   {
   message += std::make_pair(input, length);
   }

bool Botan::EMSA_PKCS1v15_Raw::verify	(	const secure_vector< byte > &	coded,
		const secure_vector< byte > &	raw,
		size_t	key_bits
	)		[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

Implements Botan::EMSA.

Definition at line 116 of file emsa_pkcs1.cpp.

   {
   try
      {
      return (coded == emsa3_encoding(raw, key_bits, nullptr, 0));
      }
   catch(...)
      {
      return false;
      }
   }
