Hash Generator
Get the MD5, SHA-1, SHA-256, and SHA-512 hash of any text. All four run live in your browser — your input never leaves the page.

MD5
SHA-1

SHA-512
Note: MD5 and SHA-1 are considered cryptographically broken — fine for checksums and non-security identifiers, but don't use them for passwords or signatures. Prefer SHA-256 or stronger.
Frequently asked questions
Which hash algorithms does this tool generate?
It computes MD5, SHA-1, SHA-256, and SHA-512 for your text all at once, live as you type, each with a one-click copy button.
Is my text sent to a server to be hashed?
No. Every hash is computed entirely in your browser, so your input never leaves the page — safe for sensitive strings.
Should I use MD5 or SHA-1 for passwords?
No. MD5 and SHA-1 are cryptographically broken and fine only for checksums or non-security identifiers; use SHA-256 or stronger for passwords and signatures.
Why does an empty input still show hashes?
Hashing an empty string is well-defined, so the tool shows those fixed hashes by default — useful as a sanity check that the output matches a known reference value.
