It may be silly to you, but the terms are "one-way process" and "one-way
function." They are two different terms with two different meanings. You
can't just decide the nouns are meaningless!

No. One process is encryption. One process is decryption. I mentioned DES
and Enigma to illustrate this. I could have mentioned DES and the one-time
pad just as well. One process results in ciphertext, the other plaintext.
