Class Pbkdf2HmacSha512

A utility class for key derivation using the PBKDF2 algorithm with HMAC-SHA512.

PBKDF2 (Password-Based Key Derivation Function 2) is a cryptographic algorithm used to derive secure keys from a password. It applies a pseudorandom function (HMAC-SHA512 in this case) to the input password and salt, repeatedly applying it for a specified number of iterations. This process increases the computational cost, making brute force attacks more difficult.

Methods

Methods

  • Derives a cryptographic key using the PBKDF2 algorithm with HMAC-SHA512.

    Parameters

    • password: Uint8Array

      The password or passphrase to derive the key from.

    • salt: Uint8Array

      A cryptographic salt to add randomness to the key derivation.

    • iterations: number

      The number of iterations to perform for increased security.

    • derivedKeyLength: number

      The desired length of the derived key in bytes.

    Returns Uint8Array

    The derived key as a binary array.

    If the key derivation operation fails.

    const password = new TextEncoder().encode('secure-password');
    const salt = new TextEncoder().encode('unique-salt');
    const iterations = 100000;
    const derivedKeyLength = 32;
    const derivedKey = Pbkdf2.pbkdf2HmacSha512(password, salt, iterations, derivedKeyLength);
    console.log('Derived Key:', derivedKey);
