#️⃣ Hash Generator
Generate MD5, SHA-1, SHA-256, SHA-512 hashes for text and files
Frequently Asked Questions
What is a hash and why use it?
A hash is a fixed-size string generated from input data using a mathematical algorithm. Hashes are used for data integrity verification, password storage, digital signatures, and file comparison. The same input always produces the same hash, but even tiny changes in input create completely different hashes.
Which hash algorithm should I use?
SHA-256 is recommended for most modern applications - it's secure and widely supported. SHA-512 offers higher security for sensitive data. MD5 and SHA-1 are legacy algorithms with known vulnerabilities - use them only for non-security purposes like checksums. Never use MD5 or SHA-1 for password hashing.
Can I hash files with this tool?
Yes! Switch to 'File' input mode to hash files up to 100MB. File hashing is useful for verifying file integrity, detecting duplicates, or ensuring downloads haven't been corrupted or tampered with.
Are hashes reversible?
No! Hash functions are one-way - you cannot reverse a hash back to the original data. This makes them ideal for password storage. However, weak passwords can be cracked using rainbow tables or brute force, so always use strong, unique passwords.
