Hash Comparison Tool
Compare file or text hashes to verify integrity. Generate and compare SHA-1, SHA-256, SHA-384, SHA-512, and MD5 hashes to ensure files haven't been tampered with.

About Hash Comparison
Hash comparison is used to verify file integrity and ensure data has not been tampered with.
Common use cases include verifying software downloads, checking file transfers, and comparing document versions.
All hash computation is performed locally in your browser - no data is sent to any server.
SHA-1: 160 bits, deprecated for security
SHA-256: 256 bits, recommended
SHA-384: 384 bits, high security
SHA-512: 512 bits, maximum security
Why Compare Hashes?
Hash comparison verifies file integrity. Downloading files should be verified against provided checksums to ensure they haven't been corrupted or tampered with.
Frequently Asked Questions
What is a hash?
A hash is a fixed-size fingerprint of data. Any change to the data produces a completely different hash, making them ideal for integrity verification.
Which algorithm should I use?
SHA-256 is recommended for most purposes. MD5 and SHA-1 are considered weak for security but still useful for checksums.
Is file hashing done locally?
Yes, all hashing happens in your browser. Files are never uploaded to any server, ensuring privacy for sensitive documents.
Can two different files have the same hash?
This is called a collision. While theoretically possible, it's computationally infeasible with strong algorithms like SHA-256.
