What's the difference between SHA-1, SHA-256, and SHA-512?

SHA-1 produces 160-bit digests (40 hex chars) and is considered weak for security. SHA-256 produces 256-bit (64 chars) and is widely used. SHA-512 produces 512-bit (128 chars) with better collision resistance on 64-bit systems.

Can I verify file integrity with this tool?

This tool generates hashes from text input only. For file integrity, use the File Checksum tool which processes entire files. Compare the hash of a downloaded file against the hash published by the source.

Why are my hashes different from online generators?

Check for: trailing newlines or spaces in your input, different encoding (UTF-8 vs ASCII), and whether the input is text vs binary. Some generators include BOM or process input line-by-line.

Is SHA-1 still safe to use?

SHA-1 is deprecated for security purposes due to known collision attacks. Use SHA-256 or SHA-512 for any security-sensitive application. SHA-1 is acceptable only for non-cryptographic purposes like checksums.

Which tools pair well with Hash Generator?

Common next steps include JWT Decoder, Base64 Encode/Decode. These related tools help continue the same workflow through generation, validation, formatting, or debugging.
