public interface BigIntegerEncryptor

Common interface for all Encryptors which receive a BigInteger (arbitrary precision) message and return a BigInteger result.

Important: The size of the result of encrypting a number, depending on the algorithm, may be much bigger (in bytes) than the size of the encrypted number itself. For example, encrypting a 4-byte integer can result in an encrypted 16-byte number. This can lead the user into problems if the encrypted values are to be stored and not enough room has been provided.
