lcPw = "password"
lcPwCharset = "ansi"
// Hash algorithms may be: sha1, md2, md5, etc.
lcHashAlg = "sha1"
// The salt should be 8 bytes:
lcSaltHex = "78578E5A5D63CB06"
lnIterationCount = 2048
// Derive a 192-bit key from the password.
lnOutputBitLen = 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.)
lcEnc = "hex"

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

? lcHexKey

// The output should have this value:
