How to Use Hash Generator
- 1
Type or paste text in the input field, or upload a file.
- 2
The hashes are calculated instantly for all algorithms.
- 3
Select which algorithm(s) you need: MD5, SHA-1, SHA-256, etc.
- 4
Click the "Copy" button next to any hash to copy it.
- 5
Use the "Verify" tab to check if an input matches a known hash.
About Hash Generator
Our Hash Generator creates cryptographic hash digests from text or files using multiple algorithms: MD5, SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512. A hash function takes any input and produces a fixed-length string — the same input always produces the same hash, and even a tiny change produces a completely different hash.
Hashes are used to verify file integrity (check if a downloaded file matches the expected hash), store passwords securely, create digital signatures, verify data hasn't been tampered with, and as unique identifiers in data systems.
Important security note: MD5 and SHA-1 are considered cryptographically broken for security purposes (collision attacks are known). For security applications like password hashing, use SHA-256 or SHA-512 (or better yet, bcrypt/Argon2 for passwords). This tool runs entirely in your browser — your sensitive input never reaches any server.
