Instead, explicitly fail when trying to derive an impossible depth, and handle the error in callers. An extended fuzzing corpus of `descriptor_parse` triggered this behaviour, which was reported by MarcoFalke. Fixes #25751.

This issue was reported to me by Marco Falke, and found with the descriptor_parse fuzz target.

2021-12-10Store version bytes and be able to serialize them in CExtPubKeyAndrew Chow
CExtPubKey does not store the version bytes for the extended public key. We store these so that a CExtPubKey can be serialized and deserialized with the same version bytes.

2021-08-23Consolidate XOnlyPubKey lookup hackAndrew Chow
The places where we need to lookup information for a XOnlyPubKey currently implement a hack which makes both serializations of the full pubkey in order to try the CKeyIDs for the lookup functions. Instead of duplicating this everywhere it is needed, we can consolidate the CKeyID generation into a function, and then have wrappers around GetPubKey, GetKey, and GetKeyOrigin which takes the XOnlyPubKey, retrieves all of the CKeyIDs (using the new GetKeyIDs() function in XOnlyPubKey), and tries their respective underlying lookup function.
2021-07-14Update secp256k1 subtree to latest upstream + adapt APIPieter Wuille
The new schnorrsig API requires changing a few arguments.

2021-05-24Add XOnlyPubKey::CreateTapTweakPieter Wuille
2021-05-24Make consensus checking of tweaks in pubkey.* Taproot-specificPieter Wuille
That results in a much safer interface (making the tweak commit to the key implicitly using a fixed tag means it can't be used for unrelated tweaking).
2021-05-10Merge bitcoin/bitcoin#21745: refactor: Add missing includes in ↵W. J. van der Laan
pubkey.cpp/pubkey.h 71c824ed6cf70b39ca09e8b3962f452f69523af0 cleaned up and added missing "include" statements for pubkey.cpp and pubkey.h (William Bright) Pull request description: #### Problem: Many symbols in the files were undefined and causing issues when I was working on building independent sections of the codebase. The hidden imports from the "secp256k1" library was a particular pain point. The other standard and missing includes are following best practices and will help with refactoring, build process and others. #### Changes: Clean up and declared imports/include for `pubkey.cpp` and `pubkey.h` ACKs for top commit: jnewbery: utACK 71c824ed6c laanwj: Code review ACK 71c824ed6cf70b39ca09e8b3962f452f69523af0 Tree-SHA512: bce605cfde24d8e3be82a596cabab7a8577fec0aef7c5e6f7a56603357046d8e8dea11ac8e3dbe79600550291be7784e35c7a55ebf40b46525b8949e4bedae96
