Description

This is really small, and not a bug - but I want to make sure that I'm not crazy and there is no good reason for doing this.

Here, electrum calls _parseASN1PrivateKey with ASN1_Node(bytes)
https://github.com/spesmilo/electrum/blob/30a7952cbb2e1c59c5eabaaee64d8a4e15a1b0cb/lib/pem.py#L168
And in _parseASN1PrivateKey, its creates s = ASN1_Node(s) from the input.
https://github.com/spesmilo/electrum/blob/30a7952cbb2e1c59c5eabaaee64d8a4e15a1b0cb/lib/pem.py#L175-L176

So ultimately, it's creating s = ASN1_Node(ASN1_Node(bytes)), which I don't see any reason for doing.

Research direction

Read lib/pem.py at _parseASN1PrivateKey and its caller around the linked lines. Confirm how ASN1_Node is constructed and remove only the redundant wrapping while preserving private-key parsing behavior. Done means the input is wrapped once and the relevant parsing checks still pass.
