How to Load a JWK Set Published at a Remote URL
See more JSON Web Signatures (JWS) Examples
Demonstrates how to load a JWK set published at a remote URL. In general, this example can fetch any JSON, or any text (non-binary) document from a remote URL. It uses the Chilkat HTTP API to do it.Chilkat VB.NET Downloads
Dim success As Boolean = False
' This example assumes the Chilkat HTTP API to have been previously unlocked.
' See Global Unlock Sample for sample code.
Dim http As New Chilkat.Http
' I put a sample JWK set at this URL: https://www.chilkatsoft.com/data/jwk-set.json
' You can test this example with it.
Dim sbJwkSet As New Chilkat.StringBuilder
success = http.QuickGetSb("https://www.chilkatsoft.com/data/jwk-set.json",sbJwkSet)
If (success = False) Then
Debug.WriteLine(http.LastErrorText)
Exit Sub
End If
' Load the JWK into a JSON object..
Dim jwkSet As New Chilkat.JsonObject
jwkSet.LoadSb(sbJwkSet)
jwkSet.EmitCompact = False
Debug.WriteLine("The full JWK Key Set:")
Debug.WriteLine(jwkSet.Emit())
' Iterate over each key...
Dim jwk As New Chilkat.JsonObject
Dim numKeys As Integer = jwkSet.SizeOfArray("keys")
Dim i As Integer = 0
While i < numKeys
jwkSet.I = i
Debug.WriteLine("---- JWK " & i & " ----")
jwkSet.ObjectOf2("keys[i]",jwk)
jwk.EmitCompact = False
Debug.WriteLine(jwk.Emit())
i = i + 1
