(VB.NET) Convert PFX to JWK Set

Demonstrates how to convert a PFX (.pfx or .p12) to a JWK Set (a JSON Web Key Set).

This example requires Chilkat v9.5.0.66 or greater.

' IMPORTANT: This example requires Chilkat v9.5.0.66 or greater.

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


Dim pfx As New Chilkat.Pfx

Dim success As Boolean = pfx.LoadPfxFile("qa_data/pfx/myEccCert.p12","MY_ECC_PFX_PASSWORD")
If (success <> True) Then
    Debug.WriteLine(pfx.LastErrorText)
    Exit Sub
End If


' To get the contents of the PFX in JWK Set form, we must first convert
' to a Java KeyStore object:
' The alias will become the key id ("kid") the the JWK Set.
' The password is an input argument that becomes the password for the JavaKeyStore.
Dim alias As String = "my_ecc_key"
Dim password As String = "secret123"
Dim jks As Chilkat.JavaKeyStore = pfx.ToJavaKeyStore(alias,password)
If (pfx.LastMethodSuccess <> True) Then
    Debug.WriteLine(pfx.LastErrorText)
    Exit Sub
End If


Dim sbJwkSet As New Chilkat.StringBuilder
' The ToJwkSet method writes to sbJwkSet.
success = jks.ToJwkSet(password,sbJwkSet)
If (success <> True) Then
    Debug.WriteLine(jks.LastErrorText)

    Exit Sub
End If



Dim jwkSet As New Chilkat.JsonObject
jwkSet.LoadSb(sbJwkSet)
jwkSet.EmitCompact = False

Debug.WriteLine(jwkSet.Emit())
