By using CipherMatrix you agree to these terms. If you do not agree, please do not use the site.

Use of the site

You may use the calculators for personal, educational and non-commercial purposes. You agree not to misuse the site, for example by attempting to disrupt it, overload it with automated requests, or copy it in bulk to republish elsewhere.

No warranty

We test our calculators carefully, but the site is provided "as is" without warranties of any kind. Results may contain errors. Always verify results that matter, especially for assessed coursework, research or engineering work. See the educational disclaimer.

Limitation of liability

To the fullest extent permitted by law, we are not liable for any loss or damage arising from your use of, or inability to use, the site or from reliance on its results.

Cryptography tools

The cryptography calculators are teaching demonstrations that use small, unpadded parameters. They are not secure and must not be used to protect real data.

Intellectual property

The site design, text and code are owned by The CipherMatrix team. Mathematical results and formulas themselves are not owned by anyone. You may link to any page.

Changes and contact

We may update these terms; continued use means you accept the updated terms. Questions: [TODO: set contactEmail in site.config.json and rebuild].
