Review Comment:
On further research, there are some options for reading PKCS 1 RSA private
keys with standard Java `KeyFactory` methods. If you can address some of the
other comments, I could add a commit to implement that element of key parsing,
which would still enable using the utility method from the github-api library,
using `PrivateKey` objects.
