Additional context Found a source and a source that mention using -lcrypto before the call that needs it in bash.

Fwiw, I transferred a working credentials file from a Windows machine and got the same message with a much shorter traceback:

Both of the references you provided are for linking in C++. I don't think that is relevant here. It sounds like you have an installation problem - did you follow all the directions for Raspberry Pi in the readme? If you did, maybe you are still missing some library (OpenSSL?) and you need to install it.

jlehenbauer commented 3 years ago

I know, but they're the only thing I could find related to the issue. It seemed to be something associated with calling the lcrypto portion of the credential encryption.

I'm pretty positive I installed all the correct dependencies. Doing a fresh install on a RPi4 just to see.
