Hi,
I am wondering if there are objective reasons for such conservative ***upper**
**hard** limits* for Argon?
} else if (!strcmp(kdf, "argon2i") || !strcmp(kdf, "argon2id")) {
limits->max_iterations = UINT32_MAX;
limits->max_memory = 4*1024*1024; /* 4GiB */
limits->max_parallel = 4;
}
(well, apart from UINT32_MAX, which makes sense, kind of)
Just to reiterate, I am not talking about minimum values, or default
values. The question is about *upper limits*.
P.S.
I was personally thinking about using ~32 threads and ~128GiB of RAM as KDF
parameters...
