    Default Qt Cryptographic Architecture OpenSSL (QCA-OSSL): problem on other Windows systems th

    Hello,

    I’m currently developing an application which uses QCA and QCA-OSSL. It always works on Linux, several friends tried it. It also works well on my Windows system. But when I’m giving the binaries and the corresponding dll’s to other people, QCA-OSSL doesn’t work and
    Qt Code:
    1. QCA::isSupported("pkey")
    To copy to clipboard, switch view to plain text mode 
    gives ‘false’, which is a problem because I use RSA which relies on pkey.

    Any ideas on how to solve this ?
    Thank you in advance,
    Benoît

    Have you deployed the OpenSSL DLL with your application? Is it somewhere that QCA can find it to load it?

    The people who tested it installed OpenSSL from here, and so did I, so I really don't understand...

    The installers at that site place the library into the Windows system directory, and hence on the PATH, only if directed: did you?
    The libraries must match the 32- or 64-bit nature of the program binary (not the Windows version) also.

    The binary is 32 bits, and so is the version we both installed. And we both kept the default parameters of the installer, so I don't see why our installations would be different.
