RSA and DES encryption and decryption with C++ on Windows

I'm a C++ programmer. I recently downloaded and installed the OpenSSL
library to my Windows 10 machine.
>From this site https://slproweb.com/products/Win32OpenSSL.html
I downloaded " Win32 OpenSSL v3.0.2" MSI
I'm using Visual Studio 2019.
Anyway, the long and short of it is that I am having a bear of a time
getting things to work. I did get base64 coding/encoding working, and I
was able to get
this guys example working:
However, his second example here
https://www.youtube.com/watch?v=MMBk_dGgiHI&ab_channel=HuiYuan, only half
worked for me. The encryption worked, but the decryption threw an error
in EVP_DecryptFinal_ex, where it returned error code 0.
These were just examples I looked at.
Anyway, I'm trying to encrypt/decrypt using RSA and DES schemes. I've
tried some of the older code examples I could find, but some of the
functions weren't recognized by my header files.
Can anyone help me with this? I want to encrypt fairly long strings. A
few hundred bytes or so. Maybe longer. If I can do a continuous stream
of blocks that would be great, as well.
Also, is there an efficient way to search this email list? I was trying
to search for similar questions but wasn't able. I guess I could use
google and the email list name?
Thanks for any help,
