Terms of Service

Last Updated: October 19, 2025

Quick Summary

Our tools are free for any legal purpose. Use them responsibly, don't try to break our service, and remember that classical ciphers aren't suitable for protecting sensitive information.

1. Acceptance of Terms

By using Cipher Utility ("the Service"), you agree to these terms. If you don't agree, please don't use the service.

These terms apply to all users, including visitors, content contributors, and anyone using our tools.

2. Service Description

Cipher Utility provides free educational cryptographic tools and resources, including:

• Classical cipher implementations (Caesar, Vigenère, ROT13, etc.)
• Modern encoding tools (Base64, URL encoding, etc.)
• Cryptographic hash functions (MD5, SHA family)
• Utility tools (password generators, text analysis)
• Educational content about cryptography and security

Educational Purpose Notice

Classical ciphers provided on this site are for educational purposes and should not be used to protect sensitive information. Modern security requires contemporary encryption standards.

3. Acceptable Use

Permitted Uses

• Educational and learning purposes
• Research and academic work
• Personal projects and experimentation
• Professional development and training
• Non-sensitive data processing

Prohibited Uses

• Any illegal activities or purposes
• Attempting to breach or test our security
• Overloading our servers with excessive requests
• Using our service to harm others
• Circumventing any access restrictions

4. Security Limitations and Warnings

Important Security Notice

• Classical ciphers (Caesar, Vigenère) are easily broken with modern techniques
• MD5 hashing is cryptographically broken and unsuitable for passwords
• These tools are educational - use proper encryption for sensitive data
• We are not responsible for any security breaches from improper usage

For protecting truly sensitive information, use modern encryption standards like AES, proper password hashing algorithms like bcrypt or Argon2, and established security libraries.

5. Privacy and Data Processing

All encryption, decryption, and encoding happens locally in your browser. We don't store or have access to any data you process with our tools.

For complete details about our data practices, see our Privacy Policy.

6. Disclaimers

The tools and information provided are for educational purposes. While we aim for accuracy, we make no warranties about completeness, reliability, or accuracy.

You're responsible for verifying that our tools suit your specific needs. For production cryptographic requirements, consult security professionals.

Service Availability: We provide the service "as is" with no guarantees about uptime or availability.

7. Limitation of Liability

Cipher Utility and its operators shall not be liable for any direct, indirect, incidental, special, consequential, or punitive damages resulting from your use of our service.

This includes, but is not limited to, damages for loss of profits, goodwill, use, data, or other intangible losses, even if we have been advised of the possibility of such damages.

8. Changes to Terms

We may update these terms at any time. When we do, the "Last Updated" date at the top will be revised.

Continuing to use the service after changes means you accept the new terms. Review these terms periodically.
