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).

LOCAL nSuccess
LOCAL oJwe
LOCAL oHeader

nSuccess := 0

oJwe := 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.
oHeader := CreateObject("Chilkat.JsonObject")
oHeader:UpdateString("alg", "A256KW")
oHeader:UpdateString("enc", "A256GCM")

//  Set the protected header on the JWE.  The protected header is integrity-protected and applies to
//  all recipients.
nSuccess := oJwe:SetProtectedHeader(oHeader)
IF (nSuccess == 0)
