The same private key is working in TypeScript sgid library.

To Reproduce
Steps to reproduce the behavior:

1. Follow the python sgid-client tutorial
2. Update the .env file with your sgid project credentials.
3. run the flask application with python -m flask run

Expected behavior
The same credentials are used in the Typescript sgid library and it worked there for ts.

Desktop (please complete the following information):

• OS: Mac Sonoma 14.5

Additional context
Using python 3.11

facing the same issue too

I did some testing and found that the format in your env variables should be declared in the format below in order for the SGID client to be initialized, hope this helps

SGID_PUBLIC_KEY="-----BEGIN PUBLIC KEY-----
your public key
-----END PUBLIC KEY-----"
SGID_PRIVATE_KEY="-----BEGIN PRIVATE KEY-----
your private key
-----END PRIVATE KEY-----"
