Could not initialize openssl library?

[Espectr0]

Hola,
what can go wrong in linux mint, that I get the message "Could not initialize openssl library"...
Do I need to configure something special?

Code: Pascal  [Select][+][-]

1.  
2. uses opensslsockets;
3. ...
4. FHTTPClient.AllowRedirect := True;
5. FHTTPClient.HTTPMethod(FMethod, AURL, FDS, [200]);
6.  

openssl is installed.

Thanks!

What protocol are you requesting? It should be TLS1.2 or higher. Usually the OpenSSL version for Mint is up to date and so will refuse anything below TLS1.2
[edit]
I just got the same error using fpcupdeluxe on windows 10.
While searching for an answer  I discoverd:
1. The current stable of openssl is 3.1
2. This is not yet supported by fpc
3. But openssl 1.1.1u (lts) is supported by fpc.
4. so check in a terminal using: openssl version

Also note fpcdupeluxe worked yesterday so currently I am at a loss.
Investigating...
I have to exactly the same laptops, with slightly differing versions of Windows 10: one works as of today, the one I am using now doesn't.
Strange. So it is probably not related to Mint, but the presence of openssl 1.1.1.

The version installed is v3.0.2 15 Mar 2022.
It is not supported by fpc?

fpc trunk only.   
or use synapse

Since when does synapse support openssl 3.x? It does not.
Also I use mainly trunk (always recent) and trunk also does not support openssl 3.x.
It supports the long time support version of openssl 1.1.1.
openssl 3.x has a quite breaking changed API as opposed to 1.x, mostly caused by the fact that it is a complete rewrite in C++ where older versions are plain C.

Since trunk R260.

See ssl_openssl3.pas.

FPC trunk has support for OpenSSL 3.0 since 2022-April:

Note that mORMot 2 has OpenSSL support from 1.1 to 3.x with automatic adaptation of the API.
It works with FPC 3.x compiler.

See https://github.com/synopse/mORMot2/blob/master/src/lib/mormot.lib.openssl11.pas for the raw API
and https://github.com/synopse/mORMot2/blob/master/src/crypt/mormot.crypt.openssl.pas for a set of high-level wrapper interfaces.

Note that some API is broken between 1.1 and 3.x e.g. some functions did disappear, be renamed, or changed parameter size (from 32-bit to 64bit).
So you need more than adding a dll name search to fully support the 3.x branch.
We tested and validated our wrapper on several Linux and Windows systems, and including Mac M1.

Also note that, from my experiment, OpenSSL 3.0 is way slower than OpenSSL 1.1 when setting up its internal structures and objects: for huge buffers, it is fine, but for small buffers, it has a huge overhead. It is about to be fixed in upcoming OpenSSL 3.1 IIRC.
