Hash Generator
Type or paste any text below to instantly compute its MD5, SHA-1 and SHA-256 hashes, all at once and updated live as you type.
How to Use the Hash Generator
- Type or paste any text into the input box.
- MD5, SHA-1 and SHA-256 hashes are computed automatically and shown live, no button needed.
- Click "Copy" next to any hash to copy that specific value to your clipboard.
- Use these hashes to verify file integrity, compare values, or generate deterministic identifiers.
Why Use This Tool?
Is my text uploaded anywhere?
No. SHA-1 and SHA-256 are computed using your browser's native, built-in crypto.subtle.digest API, and MD5 is computed by a self-contained JavaScript implementation included directly in this page's code — no external library or server call is used for any of the three. Nothing you type ever leaves your browser, which matters since people often hash passwords, API secrets or confidential file contents.
Is MD5 or SHA-1 safe to use for passwords?
No. MD5 and SHA-1 are both considered cryptographically broken for security purposes — attackers can find hash collisions relatively cheaply, and neither includes the built-in salting or slow key-stretching that password storage requires. They remain useful for non-security purposes like checksums and quick data comparison, but for storing passwords, use a dedicated algorithm such as bcrypt, scrypt or Argon2 instead.
What's the difference between MD5, SHA-1 and SHA-256?
All three are one-way hash functions that turn input text into a fixed-length hexadecimal fingerprint: MD5 produces 128 bits (32 hex characters), SHA-1 produces 160 bits (40 hex characters), and SHA-256 produces 256 bits (64 hex characters). SHA-256 is part of the modern SHA-2 family and is currently considered secure for integrity and cryptographic use, while MD5 and SHA-1 are mainly kept around for legacy compatibility and simple checksums.
Who uses a hash generator?
Developers verifying downloaded file checksums, engineers generating deterministic cache keys from input strings, and anyone learning how cryptographic hash functions behave will find this tool useful for quick, accurate hash computation without installing any software.
