The opening of the lesson

Why it matters

Getting a first key into a PIN pad, terminal or ATM used to mean:

a secure key injection room;
trained staff;
shipping devices back and forth.

Remote key loading (RKL) sends keys over the network instead, protected by public-key cryptography. ASC X9 TR-34 is the standard protocol, and the TR-34 group of this app covers it in depth.
