Duplicate Detections for Private Keys

[meme-lord]

I was using a tool that uses regexes from this repo and noticed there was some duplication.
In rules-stable.yml:

• Generic - 1702 - BEGIN RSA PRIVATE KEY
• RSA private key - -----BEGIN RSA PRIVATE KEY-----
• Asymmetric Private Key - -----BEGIN ((EC|PGP|DSA|RSA|OPENSSH) )?PRIVATE KEY( BLOCK)?-----
• private_key - -----(?:(?:BEGIN|END) )(?:(?:EC|PGP|DSA|RSA|OPENSSH).)?PRIVATE.KEY(.BLOCK)?-----

These will all match on "-----BEGIN RSA PRIVATE KEY-----"
Is there some motivation behind this duplication or could it be organized better?

"Asymmetric Private Key" and "private_key" could be merged into one regex without losing anything. There is a question if you want to keep a regex for all private keys as a whole or divide it into more specific matchers for each one or if the current duplication is what you want.
