inlinevirtualinherited

encrypt a byte string

Precondition: CiphertextLength(plaintextLength) != 0 (i.e., plaintext isn't too long); size of ciphertext == CiphertextLength(plaintextLength)

Implements PK_Encryptor.

		BufferedTransformation *	attachment = `NULL`,
		const NameValuePairs &	parameters = `g_nullNameValuePairs`
	)		const

virtualinherited

create a new encryption filter

Note: The caller is responsible for deleting the returned pointer.; Encoding parameters should be passed in the "EP" channel.

virtual size_t PK_CryptoSystem::FixedCiphertextLength ( ) const

inlinevirtualinherited

return fixed ciphertext length, if one exists, otherwise return 0

Note: "Fixed" here means length of ciphertext does not depend on length of plaintext. It usually does depend on the key length.
