Find a PFX Certificate by localKeyId

See more PFX/P12 Examples

Demonstrates Pfx.CertByLocalKeyId, which searches for a certificate whose certificate-bag localKeyId attribute matches a given value and copies it into a Cert object.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.

integer li_rc
integer li_Success
oleobject loo_Pfx
string ls_Password
oleobject loo_Cert

li_Success = 0

loo_Pfx = create oleobject
li_rc = loo_Pfx.ConnectToNewObject("Chilkat.Pfx")
if li_rc < 0 then
    destroy loo_Pfx
    MessageBox("Error","Connecting to COM object failed")
    return
end if

//  The file path is relative to the application's current working directory.  An absolute path
//  may also be used.  Supply the path appropriate to your own environment.
//  The PFX password should come from a secure source rather than being hard-coded.
ls_Password = "myPfxPassword"
li_Success = loo_Pfx.LoadPfxFile("qa_data/identity.pfx",ls_Password)
if li_Success = 0 then
    Write-Debug loo_Pfx.LastErrorText
    destroy loo_Pfx
    return
end if

//  Find a certificate whose certificate-bag localKeyId attribute matches the given value.  The 2nd
//  argument names the binary representation of the id, such as decimal, base64, or hex.
loo_Cert = create oleobject
li_rc = loo_Cert.ConnectToNewObject("Chilkat.Cert")

li_Success = loo_Pfx.CertByLocalKeyId("01","hex",loo_Cert)
if li_Success = 0 then
    Write-Debug loo_Pfx.LastErrorText
    destroy loo_Pfx
    destroy loo_Cert
    return
end if

Write-Debug "Found certificate: " + loo_Cert.SubjectCN
