bcrypt work factor versus salted SHA-256 for cross-platform R authentication
Goal Select a password-hashing strategy for an R Shiny application that must run on Linux, Windows, and macOS without requiring compiled dependencies. Constraints bcrypt via the bcrypt or openssl package provides adaptive cost but may need compilation on some platforms, and default work-factor values differ across package versions. SHA-256 is available in ba
rDoes external SHA‑256 hashing combined with NSSecureCoding guarantee complete and tamper‑free restoration of NSKeyedArchiver backups?
The goal is to confirm that a backup restored from NSKeyedArchiver is both free of tampering and semantically complete when the archiver is configured with NSSecureCoding and an external SHA‑256 hash is used to verify the archived bytes. The constraints are that NSKeyedUnarchiver’s version‑tolerant decoding will silently set missing properties to nil or defa
