DES This is the 'Data Encryption Standard'. This is a cipher that operates on 64-bit blocks of data, using a 56-bit key. It is a 'private key' system. RSA RSA is a public-key system designed by Rivest, Shamir, and Adleman. HASH A 'hash algorithm' is used for computing a condensed representation of a fixed length message/file. This is sometimes known as a 'message digest', or a 'fingerprint'. MD5 MD5 is a 128 bit message digest function. It was developed by Ron Rivest. AES This is the Advanced Encryption Standard (using the Rijndael block cipher) approved by NIST. SHA-1 SHA-1 is a hashing algorithm similar in structure to MD5, but producing a digest of 160 bits (20 bytes). Because of the large digest size, it is less likely that two different messages will have the same SHA-1 message digest. For this reason SHA-1 is recommended in preference to MD5. HMAC
