@nully0x nully0x commented Feb 26, 2024

This PR adds the ability to encode CPubKey objects to their pseudorandom elligator-swift representation. Depends on bitcoin-core/secp256k1#1129.

The first 2 commits enable the availability of that upstream code and will be removed once bitcoin-core/secp256k1#1129 is merged. Only last 3 commits need review here.
