To verify a signature ''sig'' for a BIP 118 public key ''p'':
* If the ''sig'' is 64 bytes long, return ''Verify(p, hash<sub>TapSigHash</sub>(0x00 || SigMsg118(0x00, 1) || SigExt118(0x00, 0x02), sig)'', where ''Verify'' is defined in [[bip-0340.mediawiki|BIP 340]].
* If the ''sig'' is 65 bytes long, return ''sig[64] &ne; 0x00 and Verify(p, hash<sub>TapSighash</sub>(0x00 || SigMsg118(sig[64], 1) || SigExt118(sig[64], 0x02), sig[0:64])''.

* Otherwise, fail.
