快速指南与实用说明

Integrity checks without upload

Checksums help confirm whether a downloaded, copied, or compressed file changed. This page calculates common hashes directly from the local file.

MD5 and SHA-1 remain useful for legacy compatibility, while SHA-256 and SHA-512 are stronger choices for modern integrity workflows.

Comparison and export

Paste an expected hash to automatically see whether any algorithm matches. Then copy all results or download JSON/CSV for audit records or release notes.

Processing happens in the browser whenever possible. Files and inputs do not need to be uploaded to the site server for the main workflow.

  • MD5 for legacy checksums
  • SHA-256/SHA-512 for releases
  • CRC32 for archive workflows

Checksum security limits

A checksum does not prove authorship and does not replace a digital signature. For sensitive distribution, combine hashes with cryptographic signatures and trusted channels.

常见问题

Is the file uploaded?

No by default. The browser reads the local file and calculates the hashes.

Which hash should I use?

Prefer SHA-256 or SHA-512 for modern integrity checks. MD5 and SHA-1 are mainly compatibility formats.

Can I compare an expected checksum?

Yes. Paste the expected hash and the table shows whether a result matches.

Does it work with large files?

Yes, but very large files depend on your device memory and performance.
