14:12 <jmabsd> Wait, libsecp256k1 has no secp256k1_ec_pubkey_verify(), why ?

14:12 <jmabsd> Only secp256k1_ec_seckey_verify().

14:21 <jmabsd> Indeed private keys have a limitation to their interval, so validating one makes sense.

14:22 <waxwing> jmabsd, there's a pubkey_parse

14:22 <jmabsd> oh good point hmm

14:22 <waxwing> https://github.com/bitcoin/bitcoin/blob/master/src/secp256k1/include/secp256k1.h#L246-L260

14:25 <jmabsd> waxwing: let's see in its logics if it has any failure cases.

14:26 <waxwing> jmabsd, you're thinking the function implementation might be 'return 1'? :)

14:26 <jmabsd> waxwing, lols, thanks for suggesting.

14:27 <jmabsd> waxwing, you mean as alternative to return 2 - 1;

14:31 <jmabsd> waxwing, interesting, yeah indeed there are two failure code paths in pubkey_parse.

14:32 <jmabsd> relative to input values, so certainly invalid pubkeys are valid, and parse_pubkey's documentation also discusses the possibility of an invalid pubkey.

14:36 <waxwing> jmabsd, i don't know what you mean, aren't there three failure paths here? https://github.com/bitcoin/bitcoin/blob/452bb90c718da18a79bfad50ff9b7d1c8f1b4aa3/src/secp256k1/src/eckey_impl.h#L17-L35

14:36 <jmabsd> waxwing: exactly

14:37 <waxwing> prob this is a bit offtopic though, maybe you can ask in #secp256k1 if there's something you particularly want to figure out

14:37 <jmabsd> oh it has its own channel, who could have guessed.

14:38 <jmabsd> waxwing: anyhow secp256k1_ec_pubkey_parse()'s success depends on secp256k1_eckey_pubkey_parse()'s, and for a compressed pubkey that one as you point out depend on both secp256k1_fe_set_b32()'s and secp256k1_ge_set_xo_var()'s success, and when you dig into those two they both have failure cases
