Our mission is to develop the best crypto software for resource-constrained microcontrollers.

Our crypto software is designed to be tiny and easy to use – and to take maximum advantage of Arm Cortex-M and RISC-V 32-bit hardware.

Writing correct cryptographic software is hard. Cryptographic software for deeply embedded systems, such as Internet of Things devices based on inexpensive microcontrollers, is even harder – due to constrained memory resources and processor speeds. Customers have found that our software has met the challenge, for example:

• "For our bootloader, there were hard limits regarding the memory consumption of crypto code. The ocrypto library of Oberon microsystems did simply fit. ... I can recommend Oberon's ocrypto library without any reservation."
• "Oberon microsystems understands embedded and we are proud to integrate their high-quality solutions in our devices."
