What's wrong with "mifckiku"? A key is not a cipher; it's a parameter to a
cipher, being the small amount that has to be kept secret (except for public
keys) while the cipher algorithm can be public. ckiku2=mifra3.

I like it better than my suggestions (I was a bit tired), but it's slightly figurative; apparently, {termifckiku} and {kiktermifra} are mentioned in the definition of {ckiku} for "crypto key", so I guess it's within the accepted use of {ckiku}.

I checked "hash" and "salt" in Wikipedia. Most of the languages transliterate
"hash", but all the ones that I can read except Indonesian translate "salt"
(which in the ordinary sense is "garam"). So I'd say "fancrxacu" and
"mifrxaca", but I'm not sure what to call cryptographic salt. Does it have a
source and composition? Does it flavor anything (thinking of "tsapi")?

It has none of source, composition, or flavor. It's used as a second input to a password hash function (usually by concatenating it with the actual input before running the function on the resulting string, but that's an implementation detail); it is publicly known; its purpose is to make rainbow tables infeasible as an mass attack vector; it is mostly a special case of "nonce" and is similar to "initialization vector" except for hashes instead of ciphers.
