[AES-CBC] for <ESP Encryption>: Select to set AES for the ESP encryption algorithm, and
CBC for the encryption mode. AES supports encryption keys with a key length of 128, 192,
or 256 bits. As the supported key lengths are long, it enables increased encryption strength.
CBC links the encryption result of the previous block with the next block to make it harder to
decipher the encryption.
[NULL] for <ESP Encryption>: Select to not set the algorithm for the ESP encryption method.
[SHA1] for <AH Auth.>: Select to set SHA1 as the algorithm for the AH authentication
method. 160-bit hash values are supported.
[MD5] for <AH Auth.>: Select to set MD5 as the algorithm for the AH authentication method.
128-bit hash values are supported.
Automatically Setting the Authentication and Encryption Algorithm:
Select [Auto] for <Auth./Encryption Algorithm>.
The ESP authentication/encryption methods are set. The priority for the authentication and
encryption algorithms is indicated below.
