Late 20th century systems are just black boxes, often literally. In fact they are called blackers in NSA parlance because they convert classified signals (red) into unclassified signals (black). They typically have electrical connectors for the red signals, the black signals, electrical power, and a port for loading keys. Controls can be limited to selecting between key fill, normal operation and diagnostic modes and an all important zeroize button that erases classified information including keys and perhaps the encryption algorithms. 21st century systems often contain all the sensitive cryptographic functions on a single, tamper-resistant integrated circuit that supports multiple algorithms and allows over-the-air or network rekeying, so that a singlehand-held field radio can interoperate with most current NSA cryptosystems.[1]  wikipedia NSA encryption systems
