Detailed Description

RSA class.

Important: This class has NOT been tested thoroughly by a cryptography expert.

Member Function Documentation

static void CL_RSA::create_keypair	(	CL_Random &	random,
		CL_Secret &	out_private_exponent,
		CL_DataBuffer &	out_public_exponent,
		CL_DataBuffer &	out_modulus,
		int	key_size_in_bits = `1024`,
		int	public_exponent_value = `65537`
	)			`[static]`

Create a keypair.

Parameters:

	random	= Random number generator
	out_private_exponent	= Private exponent (to decrypt with)
	out_public_exponent	= Public exponent (to encrypt with)
	out_modulus	= Modulus
	key_size_in_bits	= key size in bits
	public_exponent_value	= public exponent value

static CL_Secret CL_RSA::decrypt	(	const CL_Secret &	in_private_exponent,
		const void *	in_modulus,
		unsigned int	in_modulus_size,
		const void *	in_data,
		unsigned int	in_data_size
	)			`[static]`

Decrypt.

Warning: An exception may be thrown when decrypting if in_data is not valid. Be careful handling this, to prevent "timing attacks"

Parameters:

	in_private_exponent	= Private exponent
	in_modulus	= Modulus
	in_modulus_size	= size in bytes of in_modulus
	in_data	= Data to encrypt
	in_data_size	= size in bytes of in_data (length equals in_modulus_size)

static CL_Secret CL_RSA::decrypt	(	const CL_Secret &	in_private_exponent,
		const CL_DataBuffer &	in_modulus,
		const CL_DataBuffer &	in_data
	)			`[static]`

Decrypt.

Warning: An exception may be thrown when decrypting if in_data is not valid. Be careful handling this, to prevent "timing attacks"

Parameters:

	in_private_exponent	= Private exponent
	in_modulus	= Modulus
	in_data	= Data to decrypt (length equals in_modulus.get_size())

static CL_DataBuffer CL_RSA::encrypt	(	int	block_type,
		CL_Random &	random,
		const void *	in_public_exponent,
		unsigned int	in_public_exponent_size,
		const void *	in_modulus,
		unsigned int	in_modulus_size,
		const void *	in_data,
		unsigned int	in_data_size
	)			`[static]`

Encrypt.

Parameters:

	block_type	= 0 (private key), 1 (private key) or 2 (public key)
	random	= Random number generator
	in_public_exponent	= Public exponent
	in_public_exponent_size	= size in bytes of in_public_exponent
	in_modulus	= Modulus
	in_modulus_size	= size in bytes of in_modulus
	in_data	= Data to encrypt
	in_data_size	= size in bytes of in_data (maximum size is in_modulus_size - 11)

static CL_DataBuffer CL_RSA::encrypt	(	int	block_type,
		CL_Random &	random,
		const CL_DataBuffer &	in_public_exponent,
		const CL_DataBuffer &	in_modulus,
		const CL_Secret &	in_data
	)			`[static]`

Encrypt.

Parameters:

	block_type	= 0 (private key), 1 (private key) or 2 (public key)
	random	= Random number generator
	in_public_exponent	= Public exponent
