| comp., MS | Advanced Encryption Standard | Caighdeán Ardchriptiúcháin (A cryptographic algorithm specified by the National Institute of Standards and Technology (NIST) to protect sensitive information) |
| comp., MS | Data Encryption Standard | Caighdeán Criptiúcháin Sonraí (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 | encryption key | eochair criptiúcháin (A bit string that is used in conjunction with an encryption algorithm to encrypt and decrypt data) |
| comp., MS | encryption provider | soláthraí criptiúcháin (Software that provides encryption for sensitive data, such as passwords, in applications) |
| comp., MS | Triple Data Encryption Standard | Caighdeán Tríchriptiúcháin Sonraí (An encryption algorithm based on the Data Encryption Standard (DES)) |
