Compute and show the code signing cdhash#33
Merged
Conversation
Add a dependency-free SHA-1 / SHA-256 (libmoex must stay Qt-free) and use it to compute the Code Directory cdhash — the digest of the whole Code Directory blob per its hash type, truncated to the canonical 20 bytes. The cdhash is the identity used for notarization, provisioning, and TCC, so surfacing it makes the code signature view far more useful. SHA implementations are verified against standard test vectors. https://claude.ai/code/session_013kBiVXftgoEsyGVyrvfGok

Summary
Adds a dependency-free SHA-1 / SHA-256 (
libmoex/base/digest/Sha.h) —libmoexmust stay Qt-free, soQCryptographicHashcan't be used — and computes the cdhash in the code signature view: the digest of the whole Code Directory blob per its hash type, truncated to the canonical 20 bytes.The cdhash is the identity used for notarization, provisioning profiles, and TCC, so surfacing it makes the code signature view substantially more useful for RE/forensics.
