How to Use Hash Generator
- 1Type or paste your text into the input area.
- 2Click 'Generate Hashes'.
- 3All four hash values are computed simultaneously.
- 4Copy any individual hash using its copy button.
Frequently Asked Questions
Why isn't MD5 available?
MD5 is not supported by the browser's Web Crypto API (crypto.subtle) because it is considered cryptographically broken. SHA-256 or SHA-512 are the recommended alternatives.
Are these hashes the same as command-line sha256sum?
Yes — the SHA algorithms produce identical output to OpenSSL, sha256sum, and any other standard implementation for the same input.
Can I hash binary data?
This tool hashes text input. The text is encoded as UTF-8 bytes before hashing, which is the standard approach for text data.
About Hash Generator
Cryptographic hashes are one-way functions that produce a fixed-length fingerprint of any input. They're used to verify file integrity, store passwords securely, and create digital signatures.
Our Hash Generator uses the browser's built-in Web Crypto API (crypto.subtle) to compute SHA-1, SHA-256, SHA-384, and SHA-512 hashes. Because everything runs locally, sensitive data never leaves your device.
