Now PSBT_OUT_SP_V0_INFO provides labeled-spend public key not the base-spend
public key.
Modify test vector with labeled-spend key to the same recipient from:
two sp outputs - output 0 uses label=3 / output 1 uses label=1
to:
three sp outputs (same scan key) - output 0 uses label=1, outputs 1 and 2 uses label=2 (same spend key)
This vector excercises the BIP375 sorting outputs with same scan key properly.
The next commit will fix the validation logic and address this failing test.
bump ChangeLog to 0.1.3
bip-0375/deps/dleq.py is adapted from the BIP-374 reference code but
predates the change that treats the challenge e as a scalar (#2262).
Reduce the challenge hash mod n and reject proofs with e >= n, so the
copy used by the BIP-375 validator matches the current BIP-374
reference.
Test vectors with labels now use big-endian byte order instead of little-endian, matching BIP-352 specification
Summary of test vector changes:
- psbt structure: missing PSBT_OUT_SP_V0_INFO field when PSBT_OUT_SP_V0_LABEL set
- can finalize: one P2WPKH input / two mixed outputs - labeled sp output and BIP 32 change
- can finalize: two sp outputs - output 0 uses label=3 / output 1 uses label=1
add fake ecdh share and dleq proof to P2SH input for valid test: two inputs using per-input ECDH shares - only eligible inputs contribute shares (P2SH excluded)
remove unused return string from is_input_eligible
correctly label witness_utxo vs non_witness_utxo key in supplementary inputs
Summary of test vector changes:
removed test:
- psbt structure: empty PSBT_OUT_SCRIPT field when sending to non-sp output
modified test:
- ecdh coverage: only one ineligible P2SH multisig input when PSBT_OUT_SCRIPT set for sp output
- can finalize: one P2PKH input single-signer
- can finalize: two inputs using per-input ECDH shares - only eligible inputs contribute shares (P2SH excluded)
added test:
- can finalize: two inputs using global ECDH share - only eligible inputs contribute shares (P2SH excluded)
Add support for computing bip352 output scripts
Extract ECDH shares and public key from PSBT and aggregate both if necessary
Refactor validate_ecdh_coverage to use collect_input_ecdh_and_pubkey
