Using HMAC ()'s facility of returning the digest in a static array is not thread safe (this can't be fixed) and it is not portable to the OpenSSL forks: BoringSSL removed support for this a decade ago (so aws-lc doesn't support it either) and LibreSSL followed a few years back. There is no downside to having a 32-byte array on the stack and it would make zoitechat safe to use from other forks without the need of patching it. Add an error check for the HMAC () call and handle the error in the caller.
ZoiteChat is a GTK3 IRC client based on HexChat, available for Windows and UNIX-like operating systems.
Features include HexChat-compatible Python, Perl and Lua scripting support, a plugin API, multiple server/channel windows, spell checking, multiple authentication methods including SASL, and customizable notifications.
