Base64 Private key

[hayesOw]

Would it be possible to provide the private key in base64, i think this would be useful when using act to run the actions locally. You can load all secrets from a file with .env format and its hard to put the private key in there

@hayesOw I had the same issue. Found a hint in act manual about multiline secrets.

A line break has to be a string \n.
I tested it and it works.

You can convert a key file with this command:

sed ':a;N;$!ba;s/\n/\\n/g' ssh-key-file
