PBKDF Component

The PBKDF component supports using PBKDF1 and PBKDF2 to derive a key using a variety of algorithms.

Syntax

nsoftware.IPWorksEncrypt.Pbkdf

Remarks

The PBKDF component implements PBKDF2(Password-Based Key Derivation Function 2) and PBKDF1 described in RFC 2898.

The simplest way to use the component is to simply specify the Password and Salt and call CreateKey. Before calling CreateKey additional properties such as Algorithm, KeyLength, and Iterations may be set. The component supports a variety of algorithms including HMAC-SHA1, HMAC-SHA256, HMAC-MD5, and more.

The Version property controls whether PBKDF1 or BPKDF2 (default) is used, although it is recommended to use PBKDF2.

After calling CreateKey the derived key will be held in Key.

Code Example:

Pbkdf pbkdf = new Pbkdf();
pbkdf.Password = "password";
pbkdf.Salt = "0123456789ABCDEF";
pbkdf.KeyLength = 4096;
pbkdf.CreateKey();
      
//Now do something with pbkdf.Key
