Frequently Asked Questions

Which hash algorithm is best for file verification and security?

SHA-256 is recommended for security applications and file verification. MD5 and SHA-1 are deprecated for cryptographic use but still useful for simple checksums.

Can I reverse a hash to get the original data?

No, cryptographic hashes are one-way functions. You cannot retrieve original data from a hash.

What is the difference between MD5 and SHA-256?

MD5 is older and faster but cryptographically broken. SHA-256 is secure and recommended for current use.

Can I hash files of any size?

Yes, the tool can hash files efficiently, though very large files may take time to process.
