Data Encryption Standard (DES) is a cryptographic block cipher algorithm.
RSA is a common public key algorithm, which can be used for encryption and signature
Des code is 8 times larger than rsa
How can I translate printf("%c",M); from C to Java for my DES implementation?
By comparison des see section 3.2 and other block ciphers are much faster than the rsa algorithm
