Digital Signatures / Re: Signing XML with smartcard(private key not exportable)

« on: June 02, 2018, 08:39:02 AM »

I was excited reading the new version (9.5.0.73) Release Notes:

XmlDSigGen Now capable of using non-exportable private keys on Windows, such as for A3 certificates where the private key is on a hardware token.

I am using Gemalto K30 USB hardware token, where some certificates are stored.   
I've just tried new version ActiveX, but there is still the same problem as it was in previous version.

I can  read public key with Cert.ExportPublicKey() method,  but not the private key with Cert.ExportPrivateKey() method.

This is what I get from Cert.LastErrorText property:

Code: [Select]

ChilkatLog:
  ExportPrivateKey:
    DllDate: May 22 2018
    ChilkatVersion: 9.5.0.73
    UnlockPrefix: NONE
    Architecture: Little Endian; 32-bit
    Language: ActiveX
    VerboseLogging: 0
    exportPrivateKey:
      Failed to export private key.
      The private key is not exportable from the Windows protected store.
    --exportPrivateKey
    Failed.
  --ExportPrivateKey
--ChilkatLog


Is there a possible solution for this?
