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. Chilkat2-Python

import sys
import chilkat2

success = False

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

http = chilkat2.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.
sbJwkSet = chilkat2.StringBuilder()
success = http.QuickGetSb("https://www.chilkatsoft.com/data/jwk-set.json",sbJwkSet)
if (success == False):
    print(http.LastErrorText)
    sys.exit()

# Load the JWK into a JSON object..
jwkSet = chilkat2.JsonObject()
jwkSet.LoadSb(sbJwkSet)
jwkSet.EmitCompact = False
print("The full JWK Key Set:")
print(jwkSet.Emit())

# Iterate over each key...
jwk = chilkat2.JsonObject()
numKeys = jwkSet.SizeOfArray("keys")
i = 0
while i < numKeys :
    jwkSet.I = i
    print("---- JWK " + str(i) + " ----")

    jwkSet.ObjectOf2("keys[i]",jwk)

    jwk.EmitCompact = False
    print(jwk.Emit())
    i = i + 1

# Output:
