Readme for aws-sns-verify-

[back to package description]


Consumers utilizing SNS need to do 3 tasks:

  1. Parse the message JSON
  2. Validate signed signatures
  3. Handle subscriptions

This library encapsulates those actions.

myEchoWebhook :: MonadHandler m => m ()
myEchoWebhook = do
  message <- verifySNSMessage =<< requireInsecureJsonBody
  logDebugN message

Sign For Test

Signatures for testing are produced with the self signed certificate in this repository.

cat unsigned.txt | openssl dgst -sha1 -sign tests/key.pem | openssl base64

The certificate was produced with

openssl req -newkey rsa:2048 -new -nodes -x509 -days 3650 -keyout tests/key.pem -out tests/cert.pem
