(Xojo Plugin) PBKDF2 - Derive Key from PasswordDemonstrates how to derive a symmetric encryption key from a password using PBKDF2. This example matches the results found at this URL: http://www.di-mgt.com.au/cryptoKDFs.html#examplespbkdf
// This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. Dim crypt As New Chilkat.Crypt2 Dim hexKey As String // http://www.di-mgt.com.au/cryptoKDFs.html#examplespbkdf Dim pw As String pw = "password" Dim pwCharset As String pwCharset = "ansi" // Hash algorithms may be: sha1, md2, md5, etc. Dim hashAlg As String hashAlg = "sha1" // The salt should be 8 bytes: Dim saltHex As String saltHex = "78578E5A5D63CB06" Dim iterationCount As Int32 iterationCount = 2048 // Derive a 192-bit key from the password. Dim outputBitLen As Int32 outputBitLen = 192 // The derived key is returned as a hex or base64 encoded string. // (Note: The salt argument must be a string that also uses // the same encoding.) Dim enc As String enc = "hex" hexKey = crypt.Pbkdf2(pw,pwCharset,hashAlg,saltHex,iterationCount,outputBitLen,enc) System.DebugLog(hexKey) // The output should have this value: // BFDE6BE94DF7E11DD409BCE20A0255EC327CB936FFE9364 |
