aside from the addition of OpenSSL support a few other changes have been included: - setEngine(), as added by petrich, is depricated (not that it was ever in trunk to begin with) it has been replaced with isValidEngine() and setPreferredEngine(). - replace _generate_xor() with increment_str() _increment_str() had extra functionality that wasn't being used. ie. it could concatenate multiple successive string increments to one another automatically. but not only was that functionality not used - it also made the function less versatile. _increment_str() can be used more easily for iterative brute forcing (for example) - rename Crypt_Base::_stringShift to Crypt_Base::_string_shift (for consistency) - more expansive unit test coverage
