Hash Generator
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from any text.
About This Tool
The Hash Generator turns any text into MD5, SHA-1, SHA-256, and SHA-512 hashes. A hash is a fixed-length fingerprint of the input: the same text always produces the same hash, and a tiny change produces a completely different one. It is useful for checksums, comparing values, and verifying integrity.
SHA hashes are computed with the browser's built-in crypto API. All hashing runs locally, so your text is never uploaded.

Frequently Asked Questions
Is MD5 secure? expand_more
MD5 and SHA-1 are fine for checksums and non-security comparisons but are considered broken for security purposes. Use SHA-256 or SHA-512 when security matters.
Can I reverse a hash back to the original text? expand_more
No. Hashing is one-way by design. The original text cannot be recovered from the hash.
Is my text uploaded? expand_more
No. Hashes are computed in your browser and the text never leaves your device.
