(PowerBuilder) Get RSA Private Key in JWK Format (JSON Web Key)

Demonstrates how to get an RSA private key in JWK (JSON Web Key) format.

Note: This example requires Chilkat v9.5.0.66 or later.

integer li_rc
oleobject loo_SbPem
integer li_Success
oleobject loo_PrivKey
string ls_Jwk
oleobject loo_Json

// Note: This example requires Chilkat v9.5.0.66 or later.

// Load a PEM file into memory.
loo_SbPem = create oleobject
// Use "Chilkat_9_5_0.StringBuilder" for versions of Chilkat < 10.0.0
li_rc = loo_SbPem.ConnectToNewObject("Chilkat.StringBuilder")
if li_rc < 0 then
    destroy loo_SbPem
    MessageBox("Error","Connecting to COM object failed")
    return
end if
li_Success = loo_SbPem.LoadFile("qa_data/pem/rsa_passwd.pem","utf-8")
if li_Success <> 1 then
    Write-Debug "Failed to load PEM file."
    destroy loo_SbPem
    return
end if

// Load the PEM into a private key object.
loo_PrivKey = create oleobject
// Use "Chilkat_9_5_0.PrivateKey" for versions of Chilkat < 10.0.0
li_rc = loo_PrivKey.ConnectToNewObject("Chilkat.PrivateKey")

li_Success = loo_PrivKey.LoadEncryptedPem(loo_SbPem.GetAsString(),"passwd")
if li_Success <> 1 then
    Write-Debug loo_PrivKey.LastErrorText
    destroy loo_SbPem
    destroy loo_PrivKey
    return
end if

// Get the private key in JWK format:
ls_Jwk = loo_PrivKey.GetJwk()

// The GetJwk method will return the JWK in the most compact JSON format possible,
// as a single line with no extra whitespace.  To get a more human-readable JWK (for this example),
// load into a Chilkat JSON object and emit non-compact:

loo_Json = create oleobject
// Use "Chilkat_9_5_0.JsonObject" for versions of Chilkat < 10.0.0
li_rc = loo_Json.ConnectToNewObject("Chilkat.JsonObject")

loo_Json.Load(ls_Jwk)
loo_Json.EmitCompact = 0
Write-Debug "RSA Private Key in JWK format:"
Write-Debug loo_Json.Emit()
