Zinc: a new kernel cryptography API

API has a technical meaning: Application programming interface. This can be anything. Eg open, close, read, write, lseek, ftruncate are the basic UNIX file access API and they're all "just functions". There' also "an API" for network configuration which is build on top of AF_NETLINK sockets which is a rather different animal (and not a particularly cute or pretty one).

API is also a marketing term. Then, it means "we do stuff on the web and we're so absoluetely MODERN! that we won't even know what until next week!" (presumably, this usage is meanwhile somewhat dated).
