I have an webapp built with Laravel and i need to use a public key from a .pem file to verify some data. The key is kept in the .env file and retrieved via config/app.php
with the env()
helper. Since the .pem key needs to be on separate lines with specific length i use
characters to keep the key on one line. Problem is that when i use the
characters the variable is not cached and i cannot access it. When i remove the
characters i can retrieve the variable but the openssl_get_privatekey($key);
returns false. What am i doing wrong? Is this a Laravel or some general PHP issue?

PHP's dotenv package does not seem to support multi-line environment variables.
You should ideally keep your .pem file as a file and reference it by path like e.g.:
PEM_FILE=/path/to/file.pem
and in the config:
return [ //... "key" => file_get_contents(env('PEM_FILE'))
This makes sense since generally certificates should generally go in the dedicated certificates path on the server. If you cache the config then the actual contents of the .pem file are only read once on deployment.
However if you must put it in dotenv then you can do:
In .env
PEM_KEY="-----BEGIN RSA PRIVATE KEY----- … -----END DSA PRIVATE KEY-----"
In configs:
return [ //... "key" => str_replace("\ ", " ", env('PEM_KEY')),
Since the key is generally base64 I don't think there's a chance
