WebICSF supports two main types of cryptographic processes: Symmetric, or secret key, algorithms, in which the same key value is used in both the encryption and decryption calculations. Asymmetric, or public key, algorithms, in which a different key is used in the decryption calculation than was used in the encryption calculation.
