Problem with pem file loading for cryptobox authentication
See original GitHub issueWhile wrinting code for the FR to support cryptobox in my dart client , I tried to load a pem openssh key file:
-----BEGIN OPENSSH PRIVATE KEY-----

-----END OPENSSH PRIVATE KEY-----
I get an error that the padding is not valid. I used putty openssh-export to create the file. Any Idea? Also I have troube getting the correct seed of this PK file. Its not encoded with a password. it seems like there is some extra computation needed to extract the seed. I also posted a request on how to calculate the seed on stack exchange.

the padding thing should be fixed via https://github.com/crossbario/autobahn-python/pull/1543
I worked it out. My putty file reader still was wrong. I kept the length offset bytes in the resulting key. So taking the first 32byte is korrekt. Ther is still an issue with your padding evaluation or putty somehow does it wrong. I have no idea. I’ll keep digging.
