Mastering Regular Expressions, Base64 & WebCrypto Hashing

A practical guide to testing complex regex patterns, encoding binary data into Base64 strings, and computing SHA-256 hashes offline.

Developer utilities are everyday tools for backend and frontend engineers. Mastering pattern matching and data encoding speeds up API development and security audits.

Key Dev Suite Workflows

• **Regex Tester**: Test regular expressions against sample logs with real-time capture group extraction and flag toggles (`g`, `i`, `m`).

• **Base64 Encoder / Decoder**: Safely encode images, API authorization headers, or binary blobs into ASCII text format.

• **SHA-256 & Hash Generator**: Compute cryptographic checksums using your device WebCrypto API to verify file integrity.

All Dev Suite utilities execute 100% locally with zero server logging.
