Free Hash Generator

What is a hash generator?

A hash function turns any input into a fixed-length string of hexadecimal characters. The same input always gives the same hash, but you cannot reverse the hash back to the input. Hashes are used to verify file integrity, index data, and store password digests. This tool generates MD5, SHA-1, SHA-256, and SHA-512 for any text you enter.

How to use this hash generator

Type or paste text in the Input box and the tool computes all four hashes at once, updating as you type. Each row shows the hex digest, ready to copy. The input is treated as UTF-8, so accents and non-Latin characters hash consistently. Everything runs in your browser, so your text is never uploaded.

The algorithms

• MD5 128-bit, fast but cryptographically broken, fine for checksums, not for security
• SHA-1 160-bit, deprecated for security use
• SHA-256 256-bit, the common modern default
• SHA-512 512-bit, stronger digest from the SHA-2 family

Hash FAQ

Is hashing the same as encryption? No. Hashing is one-way and cannot be reversed. Encryption is two-way and needs a key.

Which hash should I use? For integrity checks or security, use SHA-256 or SHA-512. Avoid MD5 and SHA-1 for anything security-related.

Is my data safe? Yes. Hashing runs entirely in your browser and never sends your text anywhere.
