| Data Encryption Standard | DES-staðall (An encryption algorithm that uses a 56-bit key and maps a 64-bit input block to a 64-bit output block. The key appears to be a 64-bit key, but one bit in each of the eight bytes is used for odd parity, resulting in 56 bits of usable key) |
| Triple Data Encryption Standard | þrefaldur DES-staðall (An encryption algorithm based on the Data Encryption Standard (DES)) |
