Types of Symmetric Encryption Algorithms. Algorithms for encrypting computer data come in two main varieties: symmetric and asymmetric. Each encryption type has inherent strengths and weaknesses.

The algorithm expands a single message by up to 8 bytes. DES is a block cipher that encrypts data in blocks of 64 bits. SAS Proprietary This provides basic encryption services on all platforms and ...

DES/TDES core The eSi-DES block performs encryption and decryption of 64-bit words using the DES (Data Encryption Standard) and TDEA (Triple DES Encryption Algorithm) algorithm.
