Encryption—select the desired Encryption Algorithm, and enter the key in the field provided. For
3DES, the keys should be 24 ASCII characters and for DES, the keys should be 8 ASCII
characters.
• DES—the Data Encryption Standard (DES) processes input data that is 64 bits wide,
encrypting these values using a 56 bit key. Faster but less secure than 3DES.
• 3DES—(Triple DES) achieves a higher level of security by encrypting the data three times
using DES with three different, unrelated keys.
Authentication—select the desired SHA-1 or MD5 Authentication Algorithm, and enter the key
in the field provided. For MD5, the keys should be 16 ASCII characters. For SHA-1, the keys
should be 20 ASCII characters.
• MD5—128 bits, faster but less secure.
• SHA-1 (default)—160 bits, slower but more secure.
