PEMs downloaded from GitHub App Registration Portal have empty new line

[tlawrie]

Context:
The PEMs downloaded from GitHub App Registration Portal have an empty new line after "-----END RSA PRIVATE KEY-----"

Issue
This then causes the PEM to fail the matcher check in the code

Hey, just found this issue. Can you provide an example PEM file (replace the secret inside with random string first) and the error you are getting to reproduce this issue.

@Abhi347 can you give some explanation about this, After that, I'll start my work towards it.

Is this issue resolved ?

So the fix is essentially a white space and new line trim from what's provided.

I don't have a PEM on hand anymore but if you do up a file, you should be able to replicate
