About Checksums

  • A checksum is a small-sized block of data derived from another block of digital data for the purpose of detecting errors that may have been introduced during its transmission or storage.
  • By comparing the checksum of a received file with the original, you can verify its integrity.
  • SHA-256, SHA-384, and SHA-512 are strong cryptographic hash functions. SHA-1 is older and less secure for critical applications.
  • This tool computes checksums entirely in your browser. Your files are not uploaded to any server.

Verification Tips

  • Ensure the selected hash algorithm matches the one used to generate the original checksum.
  • Checksums are case-sensitive (usually lowercase hex). Paste it exactly as provided.
  • A mismatch indicates the file has been altered, corrupted, or is not the correct file.
  • If verifying a downloaded file, obtain the checksum from a trusted source.

Verify file integrity with ChecksumPro, your free online tool. Calculate SHA-256, SHA-512, SHA-1 hashes or verify existing checksums. Secure, client-side processing.
