(Go) WPA Key Calculation from PassPhrase to Hex

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

Chilkat Go Downloads Go Package for Windows, MacOS, Linux, Alpine Linux, Solaris

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

    crypt := chilkat.NewCrypt2()

    var wpaHexKey *string = new(string)

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

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

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

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

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

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

    wpaHexKey = crypt.Pbkdf2(pw,pwCharset,hashAlg,ssidHex,iterationCount,outputBitLen,enc)

    fmt.Println(*wpaHexKey)
