    How is your hash determined through asymmetric encryption?

    • Hash of your password

    • Hash of your user name

    • Hash of your pass phrase

    • Hash of the public key

    Correct Answer
    A. Hash of your pass phrase
    Explanation
    Asymmetric encryption involves the use of a public and private key pair. The hash of the pass phrase is used to generate the private key. The pass phrase is a secret value known only to the user, and it is used to derive the private key through a hash function. This ensures that the private key remains secure and cannot be easily guessed or accessed by unauthorized individuals. By hashing the pass phrase, a unique and fixed-length string is generated, which is then used to generate the private key for the asymmetric encryption process.
