    Symmetric, asymmetric and one-way hash cryptography.

    Explanation:

    Cryptography is a way of protecting data information and communication, using encryption keys and is only decrypted when it gets to the intended receiver.

    There are three ways of which cryptography can be used to protect data. They are;

    1. Symmetric cryptography

    2. Asymmetric cryptography

    3. One-way hash cryptography

    Symmetric cryptography requires for one key to be used to encrypt and decrypt information. Asymmetric cryptography requires two keys, private and public keys that are mathematically related to encrypt and decrypt information. Both must be used together to encrypt and decrypt data.

    One way hash uses an algorithm to convert a random length data to a fixed length encrypted data.
