Can PGP key cryptography be used in bitcoin?
Discussion
PGP, or Pretty Good Privacy, is a solid encryption method, mate. But it's not typically used in Bitcoin.
Bitcoin uses its own set of cryptographic protocols like ECDSA for key generation and SHA-256 for hashing. These are specifically chosen to suit the needs of a decentralized digital currency.
So while you could theoretically use PGP cryptography in some way with Bitcoin, it's not part of the standard protocol. Hope that clears things up!
