- iPhone users making encrypted offline backups
- Worth noticing
- A published recovery script can decrypt current record formats offline; the site cautions that copied tags allow offline passphrase guessing.
Field notes
The described write flow checks whether a tag has room, asks before replacing existing content, then reads the record back for comparison. The site publishes a deterministic test vector and a Python recovery script; its stated recovery coverage excludes records protected by a security key alone.
