| comp., MS | algoritmus DES | DES (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) |
| comp., MS | algoritmus 3DES | Triple DES An encryption algorithm based on the Data Encryption Standard (DES) (Triple DES) |
| comp., MS | algoritmus 3DES | Triple Data Encryption Standard An encryption algorithm based on the Data Encryption Standard (DES) (Triple Data Encryption Standard) |
