WPA Key Calculation from PassPhrase to Hex

See more Encryption Examples

Demonstrates how to calculate a WPA key from a passprhase and network SSID. Lianja

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

loCrypt = createobject("CkCrypt2")

// The "ps" is the WPA passphrase
lcPw = "password"
lcPwCharset = "ansi"

// Hash algorithms may be: sha1, md2, md5, etc.
lcHashAlg = "sha1"

// Specify the SSID in hex:
// For example, if the SSID is "ABC", then the 
// hex values for these us-ascii chars is "414243"
lcSsidHex = "414243"

// The WPA key calculation will always use 4096 iterations.
lnIterationCount = 4096

// The WPA hex output should be 256 bits.
lnOutputBitLen = 256

// Indicate that "hex" is to be returned.
lcEnc = "hex"

lcWpaHexKey = loCrypt.Pbkdf2(lcPw,lcPwCharset,lcHashAlg,lcSsidHex,lnIterationCount,lnOutputBitLen,lcEnc)
