Hash Generator: MD5, SHA-1, SHA-256 & SHA-512 in Your Browser
The XSular Hash Generator computes MD5, SHA-1, SHA-256, and SHA-512 digests from text or uploaded files — entirely in your browser. Use it for checksums, integrity verification, API signatures, and debugging data pipelines without sending sensitive input to a server.
Key Features
- MD5, SHA-1, SHA-256, and SHA-512 output in one view
- Hash text or upload files up to the browser limit
- Optional HMAC mode with a shared secret key
- Uppercase hex output toggle for copy-paste workflows
- 100% client-side — Web Crypto API, nothing uploaded
Common Use Cases
- Verify file integrity after download or transfer
- Generate checksums for config files and build artifacts
- Create HMAC signatures for webhook or API authentication
- Compare hashed passwords during development (never store plain MD5/SHA-1 for real auth)
- Debug ETL pipelines by confirming input hashes match expected values
Benefits
- Instant results with no account or API key
- Private — sensitive strings and files never leave your device
- Supports multiple algorithms side-by-side for quick comparison
- Free forever with no usage limits
What is a cryptographic hash?
A hash function turns any input — text or binary data — into a fixed-length fingerprint. The same input always produces the same hash, but even a tiny change in the input produces a completely different result.
This tool computes hashes entirely in your browser using the Web Crypto API (plus a built-in MD5 implementation). Nothing is uploaded.
Algorithms and use cases
Use SHA-256 or SHA-512 for checksums, integrity verification, and modern applications. MD5 and SHA-1 are included for legacy compatibility — they are not secure against deliberate tampering.
Enable HMAC mode to generate keyed hashes with a shared secret, useful for API signatures and message authentication.
