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.
