Hash Generator
Generate SHA-1, SHA-256 and SHA-512 hashes from any text using your browser's native Web Crypto API. A cryptographic hash turns input of any length into a fixed-length fingerprint; the same input always produces the same hash, and even a one-character change produces a completely different result. Developers use hashes to verify file integrity, create deterministic keys, and store non-reversible tokens. This tool computes all three algorithms at once so you can compare, and it runs entirely in your browser, so your input never leaves your device. Note: MD5 is intentionally omitted because it is not available in the Web Crypto standard and is considered broken for security; SHA-256 is the modern default.
How to use Hash Generator (SHA-1 / SHA-256 / SHA-512)
- Type or paste the text you want to hash.
- Pick SHA-1, SHA-256 or SHA-512.
- Read the hex digest and copy it.
Frequently asked questions
Which hash algorithms are supported?
This tool computes SHA-1, SHA-256 and SHA-512 digests using the browser Web Crypto API, which are the algorithms it natively exposes.
Why is MD5 not offered?
The Web Crypto API does not include MD5, and MD5 is considered broken for security use, so only the SHA family is provided here.
Are these hashes reversible?
No. Cryptographic hashes are one-way, so you cannot recover the original text from the digest. They are for verification and checksums, not decoding.
What is Hash Generator (SHA-1 / SHA-256 / SHA-512)?
Generate SHA-1, SHA-256 and SHA-512 hashes from any text using your browser's native Web Crypto API. A cryptographic hash turns input of any length into a fixed-length fingerprint; the same input always produces the same hash, and even a one-character change produces a completely different result.
Is Hash Generator (SHA-1 / SHA-256 / SHA-512) free to use?
Yes. Hash Generator (SHA-1 / SHA-256 / SHA-512) is completely free, with no sign-up and no usage limits.
Does Hash Generator (SHA-1 / SHA-256 / SHA-512) work in a web browser?
Yes. Hash Generator (SHA-1 / SHA-256 / SHA-512) runs in any modern web browser. There is nothing to download or install.
Is my data private with Hash Generator (SHA-1 / SHA-256 / SHA-512)?
Yes. Hash Generator (SHA-1 / SHA-256 / SHA-512) runs entirely on your device in your browser, so nothing you enter is uploaded to a server.
