Question:

VerifyStringENC on chilkat C

Aug 18 '16 at 08:47

I'm using chilkat lib C with code as below:

CkRsa rsa;
    rsa.put_EncodingMode("hex");
    rsa.put_Utf8(true);
    rsa.put_Charset("utf-8");
    string publicKey = AccountModel::getInstance()->getKeypublic();
    rsa.ImportPublicKey(publicKey.c_str());
    bool veri = false;
    veri = rsa.VerifyStringENC(decryptStr.c_str(), "sha-1", signature.c_str());
    ----------
    But i meet an error as below

Answer

There is no error here. The call to VerifyStringENC was successful.

NOTE: The LastErrorText will always contain information about the method call -- even when successful. This provides a means to get information in the case when a method claims success, but did not behave in an expected way.
