What is the difference of these two key files? [closed]

key1.pem looks like this:

-----BEGIN PRIVATE KEY-----
encoded data
-----END PRIVATE KEY-----

key2.pem looks like this:

-----BEGIN RSA PRIVATE KEY-----
Proc-Type: 4,ENCRYPTED
DEK-Info: AES-256-CBC,28B2F38A64661706B0BC08CE244D8CA8

encoded data
-----END RSA PRIVATE KEY-----

Why?

For key1.pem, I am using WSL and OpenSSL like so:

openssl req -x509 -nodes -days 3650 -newkey rsa:1024 -keyout key1.pem -out cert1.pem -config config.cnf 

key2.pem is generated with the Crypotgraphy Python library, like so:

    key = rsa.generate_private_key(
        public_exponent=65537,
        key_size=RSA_KEY_SIZE,
    )

    with open(KEY_FILE_NAME, "wb") as f:
        f.write(key.private_bytes(
            encoding=serialization.Encoding.PEM,
            format=serialization.PrivateFormat.TraditionalOpenSSL,
            encryption_algorithm=serialization.BestAvailableEncryption(b"passphrase"),
        ))

What is the difference between these two keys?

How do you specify the encoding if that is what is different?

I need key2 to be encoded/formatted just like key1.

Solved:

I had to change this line

encryption_algorithm=serialization.BestAvailableEncryption(b"passphrase")

to

encryption_algorithm=serialization.NoEcryption()

And it's worth noting that NoEncryption is a class, so the () are required there.
