Frequently Asked Questions
What is a cryptographic hash?
A cryptographic hash is a mathematical function that converts any input into a fixed-size string of characters. It's designed to be one-way (cannot be reversed) and collision-resistant (different inputs produce different hashes).
Which algorithm should I use?
For modern security: use SHA-256, SHA-512, SHA3, or BLAKE3. Avoid MD5 and SHA-1 for security-critical applications. BLAKE3 offers the best performance while maintaining security.
How does hash verification work?
Hash verification compares your input text's hash with a provided hash. If they match, the data hasn't been altered. This is used for file integrity checks and detecting tampering.
Is my data private?
Yes! All hashing happens entirely in your browser. Your data never leaves your device or gets sent to any server.
Can I reverse a hash?
No, cryptographic hashes are one-way functions. You cannot reverse a hash to get the original data. This is a fundamental security feature.
What's the difference between SHA-2 and SHA-3?
Both are secure NIST-approved hash functions. SHA-3 uses a different algorithm (Keccak) and was designed as an alternative to SHA-2, not a replacement. Both are considered secure.
