Encoding & Security

Encode, decode, secure.

Base64, URL encoding, JWT debugging, hashing, passwords, and secure random generation.

About Encoding & Security

Encoding makes data safe for transport; hashing provides integrity checks; random generation creates secure identifiers. These tools handle common encoding and security tasks without sending your data anywhere.

  • Base64 — Encode text or images to Base64 for APIs, data URIs, and email attachments.
  • URL encoding — Percent-encode special characters for safe URL query strings.
  • JWT debugging — Decode JSON Web Token headers and payloads to inspect claims locally.
  • Hash generation — Generate SHA-256, SHA-384, and SHA-512 hashes for integrity verification.
  • Password generation — Create strong passwords and passphrases locally with a live entropy meter.
