CryptHix is available under two licences. You choose the one that fits how you use it.
| GNU AGPL-3.0 | Commercial licence | |
|---|---|---|
| Price | Free | Paid, agreed per licence |
| Personal, research and education use | Yes | Yes |
| Use inside a company | Yes, under the AGPL terms | Yes |
| Keep the CryptHix copyright and licence notices (credit the original project) | Required | As agreed in the licence |
| Modify CryptHix and keep your changes private | No: changes you distribute or offer over a network must be published under the AGPL | Yes |
| Ship CryptHix inside a closed-source product | No | Yes |
| Offer CryptHix, or a service built on it, to others without releasing your source | No | Yes |
| Support and warranty | None | Can be included |
You need one if any of these apply:
- You want to embed or bundle CryptHix, or code derived from it, in software you do not release under the AGPL.
- You run a modified CryptHix as a hosted or network service and do not want to publish your source code.
- Your organisation's policy does not allow AGPL-licensed software.
If you only use CryptHix unmodified, or you are happy to publish your changes under the AGPL, you do not need a commercial licence.
Email arpankumar1119@gmail.com with the subject line "CryptHix commercial licence" and include:
- Your name and organisation.
- How you plan to use CryptHix (product, internal tool, hosted service).
- Roughly how many users, devices or deployments.
You will receive a written licence agreement. Nothing on this page is itself a commercial licence.
Whatever licence you use, please credit the original project:
