I'm using FTP2 version 22.214.171.124, I try to read an private key into a certStore for use with login at a ftp via S-FTP. I just use the code from the example with the method LoadPfxFile wiht correct path and password, but I get the folloging LastErrorText:
ChilkatLog: LoadPfxFile: DllDate: Nov 12 2016 ChilkatVersion: 126.96.36.199 UnlockPrefix: NONE Architecture: Little Endian; 32-bit Language: ActiveX VerboseLogging: 1 pfxPath: C:\.............\<myfile>.ppk importPfxData: pkcs12FromDb: loadPkcs12Inner: verifyHmacIntegrity: PFX does not have MacData for integrity verification. --verifyHmacIntegrity der_to_xml: Found primitive SEQUENCE or SETOF in ASN.1!

Can you please tell me what's wrong?
A .ppk is a PuTTY private key file (it's not a .pfx/.p12 file). A PFX (PKCS12) file is a format that contains one or more unencrypted certificates and one or more shrouded (encrypted) private keys. Typically, a PFX contains a certificate chain + 1 shrouded private key.
A .ppk however, is an entirely different format, and only contains a private key (no certificate).
Private keys are not stored in a Windows certificate store. Part of the X.509 certificate format is that it embeds the public part of the cert's associated private key. The cert (and its embedded public key) never need to be encrypted. If a .pfx (not .ppk) is "installed" on a Windows system, the certificate is installed into the Windows registry (unencrypted), and the private key is installed to something called the "protected store", which is encrypted.
If you have only a private key (no cert), then it make no sense to "install" it into a certificate store, because that's not what certificate stores contain.
