**Full Changelog**: https://github.com/scheiblingco/sshkey-tools/compare/0.8.2...0.9.0

(Temporarily) fixed a bug where the sign()-function would pass the RSA hash_alg to other types of signatures, which would throw an error.

Changed version to support out-of-github installation
Moved documentation to html (pdoc3)
Added verification
Added option to choose RSA hashing alg for signing
Removed test files
Added doc deployment to pages
