=== Security ===
Nucleus supports a wide variety of encryption options for secure communications to protect data at rest or in transit. Nucleus ships with OpenSSL and an OpenSSL-like package [[wolfSSL]] (formerly CyaSSL) that is far smaller than OpenSSL for designs needing encryption but limited in memory capacity.<ref>{{Cite web|url=https://www.wolfssl.com/docs/wolfssl-manual/ch5/|title=wolfSSL User Manual – Chapter 5: Portability – Documentation|language=en-US|access-date=2019-02-14}}</ref> Security protocols to protect data in transit include IPsec/IKE, SSH/SSL/TLS/DTLS. Encryption includes DES, 3DES, AES, SHA-256. [[Public-key cryptography]] algorithms include RSA. Support includes X.509, RADIUS, and 802.1X.
