Signing requests for Jira

[rjakes]

Jira requires that all requests be signed via RSA-SHA1.

Are there any examples that use RSA-SHA1 signed requests that I can look at?

Please provide a technical details for term "signed requests" in http request context. Do you mean hash in request body/header?

I originally thought that only subsequent request, after authentication, needed to be signed. Later I learned that the authentication request also needs to be signed by private key.

The Jira documentation directs you to a tutorial, which used Java libraries, so that may not be super helpful:
https://developer.atlassian.com/jiradev/api-reference/jira-rest-apis/jira-rest-api-tutorials/jira-rest-api-example-oauth-authentication.

Here is an example that uses Zend_Crytp_Rsa

Here is one that uses Guzzle:
