What is a Cryptographic Hash?
A hash function transforms any input (text or file) into a fixed-length string of characters. Even a tiny change in input produces a completely different hash. This makes hashes ideal for verifying file integrity, storing passwords, and detecting tampering.
Supported Algorithms
- SHA-1 — 160-bit hash, legacy use (avoid for security-critical applications)
- SHA-256 — 256-bit hash, widely used in TLS, Bitcoin, and digital signatures
- SHA-384 — 384-bit hash, stronger variant of SHA-2
- SHA-512 — 512-bit hash, maximum strength SHA-2 variant
Key Features
- Hash text strings or entire files
- All 4 algorithms computed simultaneously
- Compare a known hash to verify file integrity
- Uppercase/lowercase toggle
- 100% browser-based using the Web Crypto API — nothing is uploaded
How to Use
- Choose 'Text Input' or 'File Input' tab.
- Type/paste text or drop a file.
- Hash values for all algorithms appear instantly.
- Optionally paste a known hash in the Compare field to verify a match.

No. All hashing is done entirely in your browser using the Web Crypto API. Your data never leaves your device.
For most modern applications, SHA-256 is the standard choice. SHA-512 offers more security for critical applications. SHA-1 is considered weak and should only be used for legacy compatibility.
Drop your file into the File Input tab. Copy the SHA-256 hash and compare it with the hash provided by the file's source. If they match, the file is intact and unmodified.
Yes. The Web Crypto API reads the file as an ArrayBuffer and processes it locally. There is no file size limit imposed by the tool, though very large files may take a moment to process.
