Hash Generator - MD5 / SHA-1 / SHA-256 / SHA-512
Convert text into MD5, SHA-1, SHA-256, and SHA-512 hashes in one pass. Useful for file integrity checks and password verification.
Hash values
Why hashes show up everywhere
A hash is a fingerprint of data that changes entirely if even a single byte is different. That property makes it the standard tool for checking that a file has not been tampered with, for verifying a password without storing it in plain text, and for telling quickly whether two pieces of data are identical.
This tool converts your text into MD5, SHA-1, SHA-256, and SHA-512 digests in a single pass and lays them out side by side. A copy button next to each hash sends it straight to the clipboard, and every calculation runs locally in your browser so the input never leaves your device.
Who gets the most out of it
- Verifying file downloads — comparing a hash against the published checksum
- Backend and security developers — building password verification or signature values
- DevOps and infrastructure engineers — recording hashes of configs and build artifacts
- Data analysts — telling quickly whether two datasets are identical
Choosing the right algorithm
MD5 and SHA-1 are fast, but collisions have been found, so they are no longer recommended for security-sensitive uses. Reach for SHA-256 or stronger whenever passwords or signatures are involved. MD5 is still fine for checksums and quick comparisons.
