Anonymize CSV
Strip sensitive content from a column of a CSV (Comma-Separated Values) file before sharing it. Hash produces a deterministic 8-character fingerprint per value (same input → same output, useful for joins). Mask email keeps the domain visible, redacts the local part. Mask phone replaces all but the last four digits.

Caveats
The hash is a fast non-cryptographic 32-bit hash (DJB2). It's fine for de-identifying within a dataset but is not a cryptographic guarantee against reversal — for that, use a salted SHA-256 in a real ETL job.
