What is the difference between MD5, SHA-1, SHA-256, and SHA-512?

MD5 produces a 128-bit hash (32 hex characters), SHA-1 produces 160-bit (40 characters), SHA-256 produces 256-bit (64 characters), and SHA-512 produces 512-bit (128 characters). MD5 and SHA-1 are faster but less secure for cryptographic purposes. SHA-256 and SHA-512 are recommended for security-sensitive applications.

Can two different files have the same hash?

While theoretically possible (called a collision), it is extremely unlikely with SHA-256 and SHA-512. MD5 has known collision vulnerabilities and should not be used for security-critical applications. For file integrity verification, SHA-256 is the recommended standard.

Is my file uploaded to a server for hash calculation?

No, all hash calculations happen entirely in your browser using the Web Crypto API. Your files are never uploaded to any server. This ensures that even sensitive files can be hashed without any risk of exposure.

How can I use hashes to verify a downloaded file?

After downloading a file, use this tool to generate its hash. Compare the generated hash against the checksum published by the software vendor on their website. If the hashes match, the file is authentic and hasn't been modified during download.

What file size is supported?

The tool supports files of any size. Large files are processed in chunks using streaming, so even files several gigabytes in size can be hashed. The processing time depends on the file size and your device's performance.

Can I hash multiple files at once?

Currently, the tool processes one file at a time to ensure accurate results. For batch hashing, you can process files sequentially. Each file's hash results can be copied individually for your records.

Why would I use SHA-256 instead of MD5?

SHA-256 is cryptographically secure and has no known collision vulnerabilities, while MD5 has known weaknesses that make it unsuitable for security applications. For file integrity verification where security matters, always use SHA-256 or SHA-512. MD5 is still useful for quick non-security checksums.
