Delphi 7 Indy 9 Could Not Load Ssl Library: The Cause and the Cure

You can use Indy's WhichFailedToLoad() function in the IdSSLOpenSSLHeaders unit to find out why Indy could not load OpenSSL. Either the DLLs could not be loaded in memory, or the DLLs are missing exports that Indy requires.

When that error happens, you can then call Indy's WhichFailedToLoad() function in the IdSSLOpenSSLHeaders unit to find out WHY it failed. Either the DLLs themselves could not be loaded into memory, or else they are missing exports that Indy requires.

I'm currently facing this kind of problem "Could not load OpenSSL library"."WhichFailedToLoad" always returns "failed to load libeay32.dll" although I used "IdOpenSSLSetLibPath"Using Delphi 10.2 with Indy 10.6.2.5366 and tried all DLL from -Binaries for version 1.0.2 x64 (My app writing in 32bit and run on 64bit window 10)

By default, on 'Nix-based systems, Indy attempts to load the OpenSSL library files using unversioned symlinks, and if that fails then it falls back to loading specific versioned library files instead. Using symlinks is not safe because they may map to library versions you are not expecting. For instance, on modern systems, the OpenSSL unversioned symlinks may map to library files for OpenSSL 1.1.x or later, which TIdSSLIOHandlerSocketOpenSSL does not support (use this SSLIOHandler instead). Indy has IdOpenSSLSetCanLoadSymLinks() and IdOpenSSLSetLoadSymLinksFirst() functions that you can call at app startup to prevent Indy from attempting to load symlinks. Then you can deploy specific versioned library files with your app, or point Indy to a folder where they reside.

You can use Indy's WhichFailedToLoad() function after the error occurs to find out whether Indy failed to load OpenSSL because the library files failed or load, or they were missing required function exports.

To install OpenSSL in a 32-bit or 64-bit Windows, you need to copy the libeay32.dll and ssleay32.dll dynamic library files to your file system, you can download them from one of these locations:

To install OpenSSL in a 32-bit or 64-bit iOS device, you must copy the libcrypto.a and libssl.a SSL library files to your system. Download the .zip iOS OpenSSL, extract it and find the .a files in the \lib directory. You must copy the libcrypto.a and libssl.a SSL library files to these directories:

Hola, por si persiste el problema de la SSL. no es problema tanto de los indy sino mas bien que te flatan las Dll del caso.. yo tenia el mismo problema, y a la final lo soluciones, tengo mi apliocacioncita en delphi XE, con lo indy 10.5.7 y me baje las dll del link , de alli baje openssl-1.0.0d-i386-win32.zip y openssl-1.0.0d-x64_86-win64.zip , una para sistemas de 32 bits y la otra para los de 64 bits, y sannto remedio, un formulario con 3 edit y un memo, edit (de, para, asunto) y memo (cuerpo del mensaje),y el codigo siguiente en el boton enviar..

I'm developing an activexform with delphi 7 using the indy client (v.9) to connect to pop3 over ssl. Unfortunately when I load the activex in the web browser it tells me that it can't find the SSL library (ssleay32, libeay32).Does anybody know how can I work around this?

A bit more research and I quickly understood anytime I got the error "Could not load SSL library" I was using the wrong version of the DLL files and anytime I got the "Error connecting with SSL" with something like "error:00000006:lib(0):func(0):EVP lib" I was using the wrong SSLOptions.Method value.

No results with an update of OpenSSL library.Today I install again the Delphi 10.3.3 in a VM. The project I sent to you, works ok with same OpenSSL dlls in Delphi 10.3.3 but not in Delphi 10.4.As far as I can understand, TMS MQTT can not support SSL connections with Delphi 10.4I try to see sources differences between Delphi versions for indy stack and there are many.The main message from server side is: 2020-06-30T13:51:19: OpenSSL Error[0]: error:1408F10B:SSL routines:ssl3_get_record:wrong version number

rapaiz jah fiz tudo isso que falaram, nao sei mais o que fazer sempre o mesmo erro could not load ssl library,jah trablhei mais de 30 horas de servico em cima, todo tipo de rotina que tem nao internet ja tentei fazer e nada,gostaria de saber se alguem tem outra dica. obrigado.

Sr. André,Boa tarde,Parabéns, pela iniciativa.Tenho uma pergunta.Estou usando delphi 7 com indy 10 5.2, não estou conseguindo mandar e-mail para servido gmail.Por que usa TLS.Tem como me ajudar?Código que o senhor colocouEstá dando o Coult not load SSL Libary.Já copia a dll para pasta exe e também pasta SysWOW64.fonte:

Boa tarde.Utilizei o seu exemplo acima para enviar email. Já coloquei as DLLs na pasta onde está o programa e dentro da pasta bin do Delphi. Mas quando rodo ele mostra o seguinte erro: Could not load SSL library. O que pode estar faltando já que eu copiei o seu exemplo? Utilizo o Delphi 7. Desde já agradeço a sua ajuda.

The process of verifying a compact token is very simple using the delphi-jose-jwt library but before showing the code I want to clarify some (possible) confusion about the token verification and validation.

That said, the delphi-jose-jwt library contains some classes that greatly simplify the claims validation process. You can find the classes in the JOSE.Consumer.pas and JOSE.Consumer.Validators.pas units (more on this in the next article)

new: TI-group-files are now supported! If you open a groupfile, TIEdit will extract all editable files into the same folder, the groupfile resides, close all currently open files and load these extracted files into the editor. TIEdit can (and will not) create a groupfile, because a groupfile can contain much more filetypes, than TIEdit can handle. The new groupfile might be corrupted. new: MRU-Listnew: show matrices/list as textchanged: cticables.dll is no longer used. Instead TIEdit uses direct access to a patched version of libticables2-6.dll. This solves the problem with the exception generated after sending about 20 files. The library patch itself solves problems with some graylink-cables.changed: Project files have now the extension .tiprj to avoid problems with other applications. The extension is registered with TIEdit now.added: Format-menuchanged: Tokens89 is updated to Ver. 1.0.8 (fix: problems with Prgm/Func-Id and endless-loop when opening a not correctly builded groupfile variable)fixed: lock/archive attribute for all filetypes.changed: the file-tabs have icons now and only the TI filename is displayedchanged: The project-file list is a treeview with icons and only the TI filename is displayedchanged: The annoying question, whether the open files should be closed, can be suppressed in the preference-dialog.

fixed: broken font in Windows 7 (Remark: The problem is the Font TI89-JB itself. I have tried to fix this with FontForge, but without success. If anybody has more knowledge about fonts and could build a working font (italic/bold), I would be very happy!)fixed: Commands in Popupmenu of a Filetab will now use the selected and not the active filefixed: Link to real TI with some Graylink-Cables (Cynox, e.g.)fixed: Installer will now install TOKENS89.OCX completelyfixed: some minor bugschanged: TAB-key now works as expected. To enter the Store-Sign -> use Alt- -> (Right-key)changed: opening a TI-file from the explorer will now load the file in the running instance of TIEdit, instead of starting a new one.added: Full support for TI expression, string, text, list and matrix files. Data files are not supported. All these filetypes are registered by the installer with TIEdit.added: Tab-Indent/Unindentadded: Block-REM/Block-unREMadded: TIEdit reloads the opened files from the last session on startup.added: Online-Update, manual and/or automatic on start. 2ff7e9595c
