Each bitcoin and encrypted emailing are primarily based on public key cryptography. Nevertheless, they use totally different implementations, so I assume {that a} public PGP key can’t be used as a bitcoin deal with instantly.
However wouldn’t it be attainable to transform a public PGP key to a bitcoin deal with in such a approach that it may be accessed solely with the corresponding non-public PGP key (or one thing derived from it)?
If such an algorithm existed it might permit for sending cash to individuals with out them understanding something about Bitcoin, so long as they’ve a PGP key (e.g. for giving somebody just a little incentive to study one thing about Bitcoin).

No, this isn’t attainable.
Latest GPG variations do have help for Elliptic Curve crypto, with related EC keys. The EC curves supported there are totally different from the one utilized in Bitcoin, although (they do not have the identical measurement, in order that they definitely cannot be isomorphic).

Sure, technically you would.
Any 256 bit quantity can be utilized as a bit coin non-public key.
For those who hashed the PGP key with SHA256 you’ll have a personal key that might be used for bitcoin. Actually you would be utilizing your non-public PGP key as a mind pockets seed with very excessive entropy.
Edit: With all that being mentioned I nonetheless would not do it.

Including public/public could be break up between the totally different layers by enter/output knowledge.
