Not for cli but the absolute basics are pretty easy to calculate yourself. E.g. calculating a discrete log. Or the Rivest-Shamir-Wagner Time Lock Puzzles. Or proof-of-posession with hash functions or merkle trees. Takes 20 lines of python code tops.

 and am going to code proof-of-possesion of a private key with it.

Are there any tools that apply zero knowledge proofs, much like GPG for ZK?

Thanks. ChatGPT recommended [this library][1] and am going to code proof-of-possesion of a private key with it.
