Interface CryptoFilter

All Known Implementing Classes:

XORCipher

public interface CryptoFilter

minimalistic approach to decrypting a file. a class implementing this interface is required to return one character at a time from the given InputStream. the InputStream is encrypted, the client receives it clear-text. the encryption used may require you to read more than one character from the InputStream, but this is your business, as is all initialization required by your cipher, the client will be offered one deciphered character at a time.
