Frequently Asked Questions
Common questions about file hash generation
What is a file hash and why is it important?
A file hash is a unique digital fingerprint that represents the contents of a file. It's important for verifying file integrity, detecting changes or corruption, and ensuring data authenticity.
Which hash algorithm should I use?
SHA-256 is recommended for most security purposes. MD5 is fast but less secure and should only be used for non-security applications. SHA-512 offers maximum security but is slower.
Are my files uploaded to your servers?
No, all hash generation is performed locally in your browser using JavaScript. Your files never leave your device, ensuring complete privacy and security.
Can I verify a hash against a known value?
Yes, you can compare the generated hash with a known good hash value to verify file integrity. Any difference indicates the file has been modified or corrupted.
How long does hash generation take?
Hash generation time depends on file size and algorithm. Small files process instantly, while large files may take several seconds. SHA-256 offers the best balance of speed and security.
