Frequently Asked Questions
What is a hash?
A hash is a fixed-size "fingerprint" of data. The same input always produces the same hash, but you cannot reverse a hash to get the original data.
Which hash algorithm should I use?
For security: SHA-256 or SHA-512. For checksums: SHA-256 or MD5. Never use MD5 or SHA-1 for security purposes - they are cryptographically broken.
Can I decrypt a hash?
No, hashes are one-way functions. However, common passwords can be found in rainbow tables. This is why salting passwords before hashing is important.
What is the difference between MD5 and SHA-256?
MD5 produces 128-bit hashes and is broken for security. SHA-256 produces 256-bit hashes and is secure. SHA-256 is slower but much more secure.
Is my data private?
Yes, all hashing happens locally in your browser using the Web Crypto API. Your data never leaves your device.
