We need the function since 9dbbfcd388, but unfortunately it's not provided by LibreSSL.
By introducing a build time check we inform the user about the issue explicitly instead of just letting compilation fail.
GenX25519 command - Create new X25519 keypair
Help for command "GenX25519"
Purpose:
Create new X25519 keypair
Description:
Use this to create a new X25519 keypair, which can be used for WireGuard.
Both the private and public key will be shown.
The public key can be shared and is used to identify a peer.
Also, it can always be retrieved from the private key using the GetPublicX25519 command.
The private key should be kept in a secure place and never be shared.
It cannot be recovered once lost.
Usage:
GenX25519
==========================================================================================
GetPublicX25519 command - Retrieve public X25519 key from a private one
Help for command "GetPublicX25519"
Purpose:
Retrieve public X25519 key from a private one
Description:
Use this if you have a private X25519 key and want to get its corresponding public key.
Usage:
GetPublicX25519 [private]
Parameters:
private - The private X25519 key you want to get the corresponding public key of.
The files are created in a new folder to keep the source tree tidier.
Please note that only X25519/X448 keys are supported due to an OpenSSL limitation:
https://www.openssl.org/docs/manmaster/man3/EVP_PKEY_new.html
We have functions that handle AES keys in Encrypt.c/.h.
Ideally we should move them into the new files.
Our own implementation works fine, however we should use OpenSSL's one since we already link to the library.
Base64Decode() and Base64Encode() return the required buffer size when "dst" is NULL.
This allows to efficiently allocate a buffer, without wasting memory or risking an overflow.
Base64FromBin() and Base64ToBin() perform all steps, returning a heap-allocated buffer with the data in it.
Turns out %S refers to ANSI/UTF-8 and %s to UTF-16.
This commit fixes a buffer overflow reported by AddressSanitizer and removes an unnecessary conversion to UTF-16.
The open-source project began with version 1.00, build 9022.
With the exception of an informative message fallback for builds older than 9428 (2014), all checks were for closed-source builds.
- <pthread.h> included for the "pthread_t" type definition.
- <net/ethernet.h> include removed as the header doesn't exist.
- AI_ALL and AI_V4MAPPED defined to 0 as the options don't exist.

Also, the default timeout value is set to 30000 (milliseconds) instead of 10000.
The change is made because it was reported that some routers failed to connect in time.
This commit also fixes a bug which caused the server to initialize all boolean options to false.
It was caused by SiLoadProtoCfg() not checking whether the item exists in the configuration file.
CfgGetBool() always returns false if the item doesn't exist.
From a functional point of view, the main improvement is that GetIP() now always prioritizes IPv6 over IPv4.
The previous implementation always returned an IPv4 address, unless not available: in such case it failed.
This means that now connections to hostnames should be established via IPv6 if available.
From a programmer point of view, getting rid of the insane wrappers is enough to justify a complete rewrite.
As an extra, several unrelated unused global variables are removed.
Before this commit, the IP address reported by the NAT-T server was immediately discarded.
That's because the peer should be accessible via the IP address used to establish the TCP connection.
User "domosekai" (https://www.domosekai.com) pointed out that the NAT-T IP address should be taken into account.
In his case it's required due to his broadband carrier's NAT causing TCP and UDP to have different external IPs.

This greatly improves performance and reduces the binary's size (~0.2 MB vs ~5 MB).
All recent Windows versions are supported, starting with Vista.
No dialogs are created, aside from error/warning ones in case of failure.
The only dependency (aside from Windows libraries) is libhamcore.
