# aws-sns-verify
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.
```hs
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.
```sh
cat unsigned.txt | openssl dgst -sha1 -sign tests/key.pem | openssl base64
```
The certificate was produced with
```sh
openssl req -newkey rsa:2048 -new -nodes -x509 -days 3650 -keyout tests/key.pem -out tests/cert.pem
```
