cloud-integrity-check 0.1.0

Hash files into a manifest and verify their integrity after a cloud upload/download/sync — detect silent corruption, truncation or tampering. Standard-library only.

cloud-integrity-check

Hash your files into a manifest, then verify they are byte-for-byte intact after a cloud upload, download or sync. Catches silent corruption, truncation or tampering that you would otherwise not notice. Standard library only (SHA-256 via hashlib) — no dependencies, no custom crypto.

Install

pip install cloud-integrity-check

Use

# Before uploading: snapshot the integrity of a file or folder
cloud-integrity-check create ~/Documents -o documents.json

# After downloading from your cloud: verify nothing changed
cloud-integrity-check verify documents.json ~/Documents

Output reports per-file OK / CHANGED / MISSING / ADDED, and exits non-zero if anything changed or went missing — handy in scripts and CI.

As a library

from cloud_integrity_check import compute_manifest, verify

m = compute_manifest("/data")
report = verify(m, "/data")
print(report.intact, report.changed, report.missing)

Why

End-to-end encrypted clouds protect confidentiality; this verifies integrity — that what you get back is exactly what you stored. A practical companion to a zero-knowledge backup. More on private, verifiable cloud storage: priviy.com.
