About Hash Generator
Generate SHA-256, SHA-384, SHA-512, and SHA-1 hashes from text or files. Uses the Web Crypto API for secure, client-side hashing.
Frequently Asked Questions
What is a hash and how does hashing work?
A hash is a fixed-length string produced by a mathematical function from any input data. The same input always produces the same hash, but even a tiny change in the input produces a completely different hash. Hashes are one-way, meaning you cannot reverse-engineer the original data from the hash.
Which hash algorithm should I use?
SHA-256 is the most widely recommended for general use, offering a strong balance of security and performance. SHA-384 and SHA-512 provide longer output for higher security needs. SHA-1 is considered weak for security purposes but is still used for checksums and legacy compatibility.
Is my data safe?
Yes! All processing happens entirely in your browser using the built-in Web Crypto API. Your text and files are never sent to any server. No data is collected, stored, or transmitted.
Can I hash files with this tool?
Yes. You can drag and drop a file or click to select one, and the tool will compute the hash of its contents using your selected algorithm. The file is read entirely in your browser and never uploaded anywhere.
How do I verify a file hash?
Use the hash comparison section at the bottom of the tool. Paste the expected hash and the hash you generated, and the tool will tell you whether they match. This is commonly used to verify downloaded files have not been tampered with.
