About the Hash Generator
A cryptographic hash turns any input into a fixed-length string of characters. The same input always produces the same hash, but you cannot reverse a hash back to the original. Hashes are used for verifying file integrity, storing password fingerprints and generating checksums.
This tool computes SHA-1, SHA-256 and SHA-512 using the browser’s built-in Web Crypto API, and MD5 using a small bundled implementation. All hashing runs locally, so even sensitive input stays private. Note that MD5 and SHA-1 are considered weak for security-critical use — prefer SHA-256 or SHA-512.
Frequently asked questions
Can a hash be reversed?
No. Hashing is one-way. Matching hashes means matching input, but you cannot compute the input from the hash.
Which hash should I use?
For security, use SHA-256 or SHA-512. MD5 and SHA-1 are fine for non-security checksums but are considered broken for cryptographic use.
