Terms of Service

Last Updated: June 4, 2025

Quick Summary

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

1. Acceptance of Terms

By accessing and using Cipher Utility ("the Service"), you accept and agree to be bound by the terms and provision of this agreement. If you do not agree to abide by these terms, please do not use this service.

These terms apply to all users of the service, including without limitation users who are browsers, vendors, customers, merchants, and contributors of content.

2. Service Description

Cipher Utility provides free, educational cryptographic tools and resources. Our service includes:

• 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 cryptographic operations are performed locally in your browser. We do not store, transmit, or have access to any data you input into our tools.

For complete details about our data practices, please review our Privacy Policy.

6. Disclaimers

The information and tools provided by Cipher Utility are for educational purposes. While we strive for accuracy, we make no warranties about the completeness, reliability, or accuracy of this information.

Users are responsible for verifying the suitability of our tools for their specific use cases. We recommend consulting security professionals for production cryptographic needs.

Service Availability: We provide our service "as is" and make 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 reserve the right to update these terms at any time. When we do, we will update the "Last Updated" date at the top of this page.

Continued use of the service after changes constitutes acceptance of the new terms. We encourage you to review these terms periodically.
