About This Tool
A hash function converts input data of any size into a fixed-size string of characters. Common uses include verifying file integrity, storing passwords securely, and creating checksums.
This tool generates hashes locally in your browser using the Web Crypto API. Your data never leaves your device.
Frequently Asked Questions
What is a hash used for?
Hashes are used for verifying file integrity, checking passwords, creating checksums, and in cryptographic applications. Each hash is unique to the input data.
What's the difference between MD5 and SHA-256?
MD5 produces a 128-bit hash (32 hex characters), while SHA-256 produces a 256-bit hash (64 hex characters). SHA-256 is more secure and collision-resistant than MD5.
Can I reverse a hash?
No, hash functions are one-way functions. You cannot reverse a hash to get the original input. This is why they're used for password storage.
