How to Use the Hash Generator
Type or paste any text into the input box, and all four hashes — MD5, SHA-1, SHA-256, and SHA-512 — update instantly below it, each computed entirely in your browser; use the copy button next to any hash to grab it for pasting elsewhere.
The tool computes all four algorithms at once specifically so you can compare or choose the right one for your situation without switching tools.
Choosing the right algorithm for your use
As covered in the MD5-and-SHA-1-broken guide, use SHA-256 or SHA-512 for anything security-sensitive, and reserve MD5 or SHA-1 for non-security checksums, like quickly verifying two files are identical or spotting accidental corruption.
Verifying a piece of text or a downloaded file hasn't changed
As covered in the what-a-hash-function-does guide, hashing the same content twice and comparing the results is a reliable way to confirm nothing changed between the two — a single differing character anywhere in the content produces a completely different hash, making even a tiny alteration immediately obvious.
