| comp., MS | data encryption key | chave de encriptação de dados (A bit string that is used in conjunction with an encryption algorithm to encrypt and decrypt data) |
| comp., MS, Braz. | Data Encryption Standard | padrão de criptografia de dados (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) |
