> “I didn’t pay enough attention to security.” In the late 70s / early 80s there was a ton that the public didn't yet know about cryptography. Few, if any private citizens could have gotten security remotely right at that point. Remember, Diffie-Hellman was invented in 1976, and RSA in 1977, and PKI came some years after that, and DES was also from 1976/1977. As well the public's understanding of the need to do authenticated encryption came later, and the industry didn't really start catching on until the 90s, and AEAD cipher modes didn't really become a thing till the 00s, and didn't start to get used widely for another decade, and so on and on.
