// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

loCrypt = createobject("CkCrypt2")

lcPw = "password"

lcPwCharset = "utf-8"

// Such as sha256, sha512
lcHashAlg = "sha256"

// 16 bytes
lcSaltHex = "78578E5A5D63CB0668AB39B21C8637FA"

lnIterationCount = 100000

// Derive a 256-bit key from the password.
lnOutputBitLen = 256

// 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.)
lcEnc = "hex"

lcHexKey = loCrypt.Pbkdf2(lcPw,lcPwCharset,lcHashAlg,lcSaltHex,lnIterationCount,lnOutputBitLen,lcEnc)

? lcHexKey

// Sample output:
