Understanding Hash Algorithms
- MD5: 32 characters, fast but broken for security. Use for non-critical checksums.
- SHA1: 40 characters, deprecated for security. Use for legacy systems only.
- SHA256: 64 characters, secure. Recommended for most applications.
- SHA512: 128 characters, most secure. Use for high-security requirements.
Frequently Asked Questions
What is a hash?
A hash is a fixed-length string generated from input data. The same input always produces the same hash, but you cannot reverse a hash to get the original input.
Is this tool secure?
Yes! All hashing happens in your browser. Your data never leaves your device.
What's the difference between MD5, SHA1, SHA256?
They differ in security level and output length. SHA256 is currently recommended for security applications.
Is this tool free forever?
Yes — 100% free forever. No signup, no premium tier, no tracking.
