What it shows

  • Encryption uses cryptographic keys to protect data reversibly.
  • Hashing produces fixed one-way digests ideal for passwords and checksums.
  • Tokenization replaces sensitive payloads with non-algorithmic surrogate IDs.

The takeaway

Encrypt what you must read back, hash what you verify, and tokenize what you must keep out of scope.
