for ESP authentication. Options include:

zMD5: MD5 (Message Digest Algorithm) takes a message of arbitrary length and generates a 128-bit message digest.

zSHA: SHA (Secure Hash Algorithm) takes a message less than the 64th power of 2 in bits and generates a 160-bit message digest.

ESP Encryption: Select the algorithm used to encrypt the data for ESP encryption. Options include:

NONE: Performs no encryption.

DES: DES (Data Encryption Standard) encrypts a 64-bit block of plain text with a 56-bit key. The key should be 8 characters.

3DES: Triple DES, encrypts a plain text with 168-bit key. The key should be 24 characters.

AES128: Uses the AES algorithm and 128-bit key for encryption. The key should be 16 characters.
