WebJun 6, 2024 · Three-key triple Data Encryption Standard (3DES) is permissible in existing code for backward compatibility. All other block ciphers, including RC2, DES, 2-Key 3DES, DESX, and Skipjack, should only be used for decrypting old data, and should be replaced if used for encryption. Web, CTR-mode encryption enables effective utilization of the above features. For many ciphers, a well-optimized implementation of CTR-mode encryption on a processor such as an Pentium III, Itanium, Alpha, or a Motorola AltiVec, may be substantially faster (even more than four times [8]) than a well-optimized implementation of CBC-mode encryption.
