how to change signature method?

[wivaku]

In Signer.gs I see a reference to signature_method (line 48), how do I set this value (in my case to: PLAINTEXT) when using the library?

The library currently doesn't expose that option, but it should be fairly easy to create a setter and pass it through. Out of curiosity, which API uses PLAINTEXT signatures?

[wivaku]

That would be great Erick. The API: http://www.freshbooks.com/developers/authentication

Because all requests must use SSL, only the PLAINTEXT signature method is supported.

I need RSA-SHA1 for Jira.

I've added support for PLAINTEXT, but unfortunately RSA isn't supported in Apps Script and therefore won't be possible/feasible in this library.
