SHA-1 Hash Generator and Verifier

Generate and verify SHA-1 hashes for text and file content.

About SHA-1 Encrypt Verifier

Our SHA-1 Encrypt Verifier allows users to generate and verify SHA-1 hashes for text and file content. Use this tool to hash data with SHA-1, compare existing hashes, and experiment with hashing features. While SHA-1 is outdated for security-critical tasks, it still has uses for integrity checks.

How to Use the SHA-1 Encrypt Verifier?

  1. Enter the text you want to hash in the "Input Text" field, or upload a file.
  2. Select the appropriate input encoding (UTF-8, Base64, or Hexadecimal).
  3. Adjust the number of hash iterations if needed (default is 1).
  4. The SHA-1 hash will be generated automatically if "Auto-update" is enabled.
  5. Otherwise, click the "Generate SHA-1" button to create the hash.
  6. To verify a hash, switch to the "Verify SHA-1" tab.
  7. Enter the text or upload the file you want to verify.
  8. Enter the SHA-1 hash you want to compare against in the "Hash to Compare" field.
  9. Choose whether the comparison should be case-sensitive.
  10. Click "Compare Hashes" to check if they match.
  11. Use the "Copy Hash" button to copy the generated hash to your clipboard.
  12. Use the "Download Hash" button to save the hash as a text file.
  13. Use the "Paste from Clipboard" button to quickly input text from your clipboard.
  14. Click "Reset" to clear all fields and start over.

Key Features and Tips

  • Auto-update: Automatically generate the hash as you type.
  • Case-sensitive comparison: Choose whether hash comparison should be case-sensitive.
  • Multiple input encodings: Support for UTF-8, Base64, and Hexadecimal input.
  • Hash iterations: Apply multiple rounds of SHA-1 hashing for increased security.
  • Password visibility toggle: Show/hide the input text for sensitive information.
  • File upload: Generate SHA-1 hash from file contents.
  • Clipboard integration: Paste text directly from the clipboard.

Important Notes

  • SHA-1 is a one-way hash function and cannot be decrypted.
  • SHA-1 is no longer considered cryptographically secure for certain applications.
  • This tool is for educational and non-security-critical purposes only.
  • For secure hashing, consider using SHA-256 or other more robust algorithms.
  • Multiple hash iterations can increase security but also increase computation time.
