Frequently Asked Questions
What is the difference between MD5 and SHA-256?
MD5 produces a 128-bit hash and is considered cryptographically broken. SHA-256 produces a 256-bit hash and is widely used in security applications. Always prefer SHA-256 or higher for security-critical use cases.
Can I hash a file?
Yes — use the File tab to hash a file directly in your browser. The file is never uploaded; hashing runs locally.
Are these hashes reversible?
No. Cryptographic hash functions are one-way — you cannot derive the original input from the hash output.
