WPA Key Calculation from PassPhrase to Hex

See more Encryption Examples

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

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

    let crypt = CkoCrypt2()!

    var wpaHexKey: String?

    // The "ps" is the WPA passphrase
    var pw: String? = "password"
    var pwCharset: String? = "ansi"

    // Hash algorithms may be: sha1, md2, md5, etc.
    var hashAlg: String? = "sha1"

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

    // The WPA key calculation will always use 4096 iterations.
    var iterationCount: Int = 4096

    // The WPA hex output should be 256 bits.
    var outputBitLen: Int = 256

    // Indicate that "hex" is to be returned.
    var enc: String? = "hex"

    wpaHexKey = crypt.pbkdf2(password: pw, charset: pwCharset, hashAlg: hashAlg, salt: ssidHex, iterationCount: iterationCount, outputKeyBitLen: outputBitLen, encoding: enc)

    print("\(wpaHexKey!)")
