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

See more JSON Web Signatures (JWS) Examples

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.

PowerBuilder

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

li_Success = 0

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

// Load a PEM file into memory.
loo_SbPem = create oleobject
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
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
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()

// Sample output:
// {
