Need to quickly generate a hash from a string? Whether you’re verifying file integrity, securing data, or just experimenting with cryptographic tools, this simple hash generator makes it easy.
Just paste your data, select a hashing algorithm (like SHA-256 or SHA-512), and click the button to get your hash instantly—right in your browser. No uploads, no tracking, no fuss.
What is a Hash?
A hash is a one-way encryption method that transforms any input (like text) into a fixed-length string of characters. Commonly used for:
-
Storing passwords securely
-
Checking file integrity (like verifying downloads)
-
Digital signatures and blockchain systems
The hash output is unique to the input—change just one character and the entire hash changes. It’s not reversible, which means you can’t decode a hash back to the original input.
Which Algorithm Should I Use?
-
SHA-1 – Older, faster, but less secure. Use only for non-critical tasks.
-
SHA-256 – A solid modern choice for most hashing needs.
-
SHA-384 / SHA-512 – Longer outputs, more secure, often used in high-security contexts.
Unless you’re sure you need something specific, SHA-256 is generally the best option.
