private key files and password protected private key files

[james-ctc]

There is the option to protect private keys with a password (passed to the constructor of EvseSecurity).
The result is a PEM file that starts "-----BEGIN ENCRYPTED PRIVATE KEY-----"
When there is no password the following would be expected: "-----BEGIN PRIVATE KEY-----"
(TPM keys start with other strings)

At the moment when there is no password specified an empty password is used and the resulting file is still "-----BEGIN ENCRYPTED PRIVATE KEY-----".

I was hoping to use a generated key for mosquitto TLS and mosquitto doesn't support encrypted private key files.
My work around is to use OpenSSL to remove the encryption:

openssl pkey -in encrypted_key.pem -passin "pass:" -out unencrypted_key.pem

Perhaps EvseSecurity should be updated to generate unencrypted key files when no password is specified (which would match expectation).

Certainly not intended behavior, will look into.
