Set the JWE Protected Header

See more JSON Web Encryption (JWE) Examples

Demonstrates Jwe.SetProtectedHeader, which sets the integrity-protected JWE header from a JsonObject. The header specifies the key-management algorithm (alg) and content-encryption algorithm (enc).

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

success = 0

set jwe = CreateObject("Chilkat.Jwe")

'  Build the JWE protected header.  The "alg" member names the key-management algorithm and the "enc"
'  member names the content-encryption algorithm.
set header = CreateObject("Chilkat.JsonObject")
success = header.UpdateString("alg","A256KW")
success = header.UpdateString("enc","A256GCM")

'  Set the protected header on the JWE.  The protected header is integrity-protected and applies to
'  all recipients.
success = jwe.SetProtectedHeader(header)
If (success = 0) Then
    outFile.WriteLine(jwe.LastErrorText)
    WScript.Quit
End If

outFile.WriteLine("Protected header set.")

outFile.Close
