Hash Generator — MD5, SHA-1, SHA-256, SHA-384 & SHA-512
Generate cryptographic hashes from any text in one place. Paste or type your input and this tool instantly computes MD5, SHA-1, SHA-256, SHA-384 and SHA-512 checksums, updating live as you type. Copy any hash with one click and switch between lowercase and uppercase output. Everything runs in your browser using the Web Crypto API, so your text is never uploaded to a server.
Hashes update as you type. Text is encoded as UTF-8 before hashing.
MD5 and SHA-1 are fine for checksums and file integrity, but they are broken for passwords and signatures — use SHA-256 or stronger there.

Frequently asked questions
What is a hash and what is it used for?
A hash is a fixed-length fingerprint of your input produced by a one-way function. The same text always yields the same hash, so hashes are used to verify file integrity, store passwords safely, deduplicate data and create checksums. You cannot reverse a hash back into the original text.
What is the difference between MD5, SHA-1 and SHA-256?
They differ in output length and security. MD5 produces a 128-bit hash and SHA-1 a 160-bit hash, but both are broken and unsafe for security use. SHA-256, SHA-384 and SHA-512 are part of the SHA-2 family and remain secure for passwords, signatures and certificates.
Is MD5 still safe to use?
For non-security tasks like file checksums and detecting accidental changes, MD5 is fine and fast. It is not safe for passwords, digital signatures or anything an attacker might target, because collisions can be created deliberately. Use SHA-256 or stronger for security.
Is my text sent to a server?
No. All hashing happens locally in your browser using the built-in Web Crypto API and a self-contained MD5 implementation. Nothing you type is uploaded, logged or stored, so it is safe to hash private or sensitive text.
Why do the same words give a different hash elsewhere?
Usually because of encoding or hidden characters. This tool hashes the UTF-8 bytes of your exact input, including spaces and line breaks. A trailing newline, different encoding, or an extra space will change the hash completely.
