| 3 // This DES class has been extracted from package Acme.Crypto for use in VNC. | |
| 4 // The bytebit[] array has been reversed so that the most significant bit | |
| 5 // in each byte of the key is ignored, not the least significant. Also the | |
| 6 // unnecessary odd parity code has been removed. | |
