If you want a to get this stuff into your head reasonably fast, go implement a curve. Then do it again, but in Rust (or C) and in constant-time. Then do it again, but actually computationally efficiently (i.e. optimize the hell out of a Rus

Tink addresses things libsodium doesn't really do. Native support for AWS Key Management System and its equivalent on other cloud platforms is a huge win; we should all be using more of these. But libsodium would have to start mandatin

Note that the spec[1] requires that this tops at an implementation-defined size of integers, so you're likely not getting out of writing bignum code yourself (and even fifimplemented, the bignum operations may likely be variable-time a

Wait, doesn't this mean that the BSD sockets API is inherently dependent on UB, casing different socket types to each other and sometimes only using the first few members, or am I misunderstanding you?

C has been making strides towards complete Unicode support. I've been having trouble following along though: Am I correct in assuming that there's no actual multi-byte UTF-8 to UTF-32 Rune function and the best approximation dep
