OpenSSL: Forward-port release/3.5 improvements
The changes made in this file are detailed in release/3.5 commits 1f30c8943bf2ca3 through 92c04c6b9dbdd11 inclusive. Some slight alterations are necessary; librb instead of libratbox, snprintf() instead of rb_snprintf(), etc. Also, release/4 has offline certificate digesting functionality. For more insight, simply diff the openssl.c between release/3.5 and release/4.

/*
|
||||
* A long time ago, in a world far away, OpenSSL had a well-established mechanism for ensuring compatibility with
|
||||
* regards to added, changed, and removed functions, by having an SSLEAY_VERSION_NUMBER macro. This was then
|
||||
* renamed to OPENSSL_VERSION_NUMBER, but the old macro was kept around for compatibility until OpenSSL version
|
||||
* 1.1.0.
|
||||
*
|
||||
* Then the OpenBSD developers decided that having OpenSSL in their codebase was a bad idea. They forked it to
|
||||
* create LibreSSL, gutted all of the functionality they didn't want or need, and generally improved the library
|
||||
* a lot. Then, as the OpenBSD developers are want to do, they packaged up LibreSSL for release to other
|
||||
* operating systems, as LibreSSL Portable. Think along the lines of OpenSSH where they have also done this.
|
||||
*
|
||||
* The fun part of this story ends there. LibreSSL has an OPENSSL_VERSION_NUMBER macro, but they have set it to a
|
||||
* stupidly high value, version 2.0. OpenSSL version 2.0 does not exist, and LibreSSL 2.2 does not implement
|
||||
* everything OpenSSL 1.0.2 or 1.1.0 do. This completely breaks the entire purpose of the macro.
|
||||
*
|
||||
* The ifdef soup below is for LibreSSL compatibility. Please find whoever thought setting OPENSSL_VERSION_NUMBER
|
||||
* to a version that does not exist was a good idea. Encourage them to realise that it is not. -- amdj
