Lazysodium: An open-source Java and Android Cryptography library

Lazysodium is a new Java and Android open-source cryptography library based on Libsodium.

Poor cryptography on Android and Java

We created Lazysodium because we had no idea that the state of cryptography on Android and Java was very poor. We wanted our Android app Recordo to be properly secured. Here's the bare minimum we wanted to do:

• We wanted Recordo to be able to derive subkeys from master keys.
• We wanted Recordo to be able to end-to-end encrypt all your data using those subkeys.
• We wanted Recordo to be able to work offline and online.

Open-source has its pros and cons. A major con being lack of maintenance. Sure, a software developer could just fork the existing library and implement the features they need, but then the onus is on them to provide updates to their fork and merge upstream features. We want our open-source work to remain independent of our main business, thus we have setup a Patreon page and a Terl Supporter page for us to receive contributions towards maintenance of our open-source projects.

Lazysodium is effortless and powerful

Lazysodium makes cryptography effortless again. You don't need to compile any native C libraries, but we make it easy for you to self-provision those C native libraries. You can start coding straight away in two forms. As long as you follow the Libsodium docs, you won't get lost. The full feature list is here.

To get started just follow the instructions for Android or Java on this page. Happy coding!
