Usage

Verify Slack signature:

from slack_utils.signature import verify


verify(
    request_headers['X-Slack-Signature'],
    request_headers['X-Slack-Request-Timestamp'],
    request_body,
    slack_signing_secret
)

If signature is valid verify method will return True. Otherwise SlackException will be thrown.

Apart from signature verify method will validate request timestamp. Requests older than 60 seconds will trigger error.
