Enter a key of 16 Hex digits, e.g. '1234567890ABCDEF'

■You must enter an Encryption Key if the Encryption Transform is DES. The key for DES must be a hexadecimal string of 16 characters, using Hex characters only: '0'-'9', 'A'-'F' and 'a' - 'f'. No key entry appears if the encryption transform is NULL.

■You must specify an Authentication Type. The default is ESP, and the choices are ESP, None, or AH. ESP provides confidentiality over the IP payload and optional authentication of the IP payload and ESP header. AH (Authentication Header) provides authentication over the immutable parts of the IP header, AH header and the IP payload. ESP is preferred.

■You must specify an Authentication Transform if the Authentication Type is anything other than None. The default is HMAC-MD5-96, and the choices are HMAC-MD5-96or HMAC-SHA1-96for both AH and ESP.

■You must specify an Authentication Key if the Authentication Type is anything other than None. The key must be an ASCII string of up to 48 characters for both HMAC-MD5-96 and HMAC-SHA1-96.

Key: The key is a hexadecimal entry of 16 bytes (32 characters of input) for MD5 and 20 bytes (40 characters of input) for SHA1. It is not possible to view the Encryption Keys or Authentication Key once they have been set.
