infoAbout Hash Functions
A hash function converts data of any size into a fixed-length string. The same input always produces the same hash.
Hashes are one-way — you cannot reverse a hash to get the original data.

Security Note
MD5 and SHA-1 are considered cryptographically broken for security purposes. Use SHA-256 or SHA-512 for security-sensitive applications like file integrity verification.
How it works
Enter Input
Type or paste text, or upload any file. The data stays in your browser and is never sent to a server.
Choose Algorithms
Select one or more hash algorithms. SHA-256 and SHA-512 use the Web Crypto API for native performance.
Copy Results
Click any hash to copy it. Use "Copy All" to get all hashes at once, formatted with labels.
Frequently Asked Questions
Common questions about this tool and how it works.
A hash function takes input data (text, files, etc.) and produces a fixed-length string of characters called a digest. The same input always produces the same hash, but even a tiny change in input produces a completely different hash. Hashes are one-way — you cannot reverse them to get the original data.
