Qt Crypto++ and Botan

samaraz

In encryption, I need to install crypto ++ or botan to decrypt, but I can't setup resources old how can I do thanks

Hi and welcome to devnet,

You might want to state more clearly what your issue is.
Also, which version of Qt you are using, on which OS etc...

samaraz

hello I want to send encrypted text and learn how to add botan or crypto ++ library to Qt to decrypt I am using Qt version 5.15.2

SGaist

They are C++ libraries so just use them as any other library.

You are not even stating if you use cmake or qmake to handle your project.

samaraz

sorry i'm newer i work with cmake a little weak in english

SGaist

Do you have either of these libraries installed into your system ?

Do you already have a Qt project ready ?

Which OS are you on ?
Which version of Qt are you using ?

samaraz

I am using and Crypto ++ on Windows I downloaded from here 8.0
https://cryptopp.com/
windows 10
I don't have a ready project, I just need to decrypt with md5

SGaist

The first step would be to have a working cmake project and then add crypto++.

If you know the steps to add crypto ++, you can share

SGaist

Use find_library

This cmake wiki entry is relevant as well.

I’m not a cryptographic expert, very far from it but if I’m not mistaken md5 is only a hashing algorithm (not even a very secure one) so you can’t decrypt it. If you just need hashing QCryptographicHash can produce md5 (or sha) hashes without the need for external libraries.

@samaraz md5 should absolutely NOT be used for any sort of cryptography. You can use it as an integrity check instead of CRC but that's it.
