Create .p7s Signature with HSM / Smartcard

VBScript example showing how to use a CSP (Cryptographic Service Provider) for a smart card / HSM (Hardware Security Module) to create a .p7s (PKCS7) output file. This example uses the NCipher HSM CSP.

Download Chilkat Crypt ActiveX

set crypt = CreateObject("Chilkat.Crypt2")

'  Any string argument automatically begins the 30-day trial.
success = crypt.UnlockComponent("30-day trial")
If (success <> 1) Then
    MsgBox "Crypt component unlock failed"
    WScript.Quit
End If

'  Find our digital certificate from the Current User certificate store.
'  Note: There are several other ways to load your certificate
'  into a Chilkat cert object.  You may load directly from a .cer file,
'  PEM file, pfx, etc.
set ccs = CreateObject("Chilkat.CreateCS")

Set certStore = ccs.OpenCurrentUserStore()

Set cert = certStore.FindCertBySubjectCN("Chilkat Software, Inc.")
If (cert Is Nothing ) Then
    MsgBox cert.LastErrorText

    WScript.Quit
End If

'  Tell the crypt component to use this cert.
crypt.SetSigningCert cert

'  To use an HSM or smartcard, create a CSP object,
'  set the service provider, and then tell the Chilkat Crypt
'  component to use the CSP:
'  This example uses the NCipher HSM.  The
'  provider names must be specied exactly.
'  The NCipher provider names are:
'  PROV_RSA_FULL ("nCipher Enhanced Cryptographic Provider")
'  PROV_RSA_AES ("nCipher Enhanced RSA and AES Cryptographic Provider")
'  PROV_RSA_SCHANNEL("nCipher Enhanced SChannel Cryptographic Provider")
'  PROV_DSS_DH ("nCipher Enhanced DSS and Diffie-Hellman Cryptographic Provider")
'  PROV_DH_SCHANNEL ("nCipher Enhanced DSS and Diffie-Hellman SChannel Cryptographic Provider")

'  We'll be using the RSA FULL provider:
set csp = CreateObject("Chilkat.Csp")
csp.ProviderName = "nCipher Enhanced Cryptographic Provider"

'  Tell the crypt object to use the CSP:
crypt.SetCSP csp

'  We can sign any type of file, creating a .p7s detached signature as output:
success = crypt.CreateP7S("test.xml","test.p7s")
If (success = 0) Then
    MsgBox crypt.LastErrorText

    WScript.Quit
End If

MsgBox crypt.LastErrorText
'  Verify the signature...
crypt.SetVerifyCert cert

success = crypt.VerifyP7S("test.xml","test.p7s")
If (success = 0) Then
    MsgBox crypt.LastErrorText

    WScript.Quit
End If

MsgBox "Success!"
