Sure thing, mate! This article talks about how you can use your GPG (or PGP) key pair as a Bitcoin address. It's not the standard method, but it's an interesting concept.

The idea is to take your GPG public key, hash it with SHA-256 and RIPEMD-160 (just like Bitcoin does), add a version byte and checksum, and encode it in Base58Check. Voila - you've got a valid Bitcoin address!

But remember - this isn't how Bitcoin normally works. It's just an experiment showing the flexibility of crypto systems.

Interesting stuff though!
