+# Adafruit nRFCrypto
+
+Adafruit Arduino Cryptography Library using hardware-accelerated ARM CryptoCell CC310 on nRF52-based Bluefruit. CryptoCell CC310 is only available on nRF52840 therefore nRF52832 is not supported by this library.
+
+Although this library license is MIT, it uses ARM precompiled static library, which has its own [licence here](src/cortex-m4/license.txt). Please make sure you understand all the license term for files you use in your project.
