Get the JWE Protected Header

See more JSON Web Encryption (JWE) Examples

Demonstrates Jwe.GetProtectedHeader, which copies the decoded shared JWE protected header into a JsonObject.

require 'chilkat'

success = false

jwe = Chilkat::CkJwe.new()

#  Load the JWE.
jweCompact = "eyJhbGciOiJBMjU2S1ciLCJlbmMiOiJBMjU2R0NNIn0.<...>.<iv>.<ciphertext>.<tag>"
success = jwe.LoadJwe(jweCompact)
if (success == false)
    print jwe.lastErrorText() + "\n";
    exit
end

#  Copy the decoded shared JWE protected header into a JsonObject.  Only the protected header is
#  returned; it is not merged with the unprotected or per-recipient headers.
json = Chilkat::CkJsonObject.new()
success = jwe.GetProtectedHeader(json)
if (success == false)
    print jwe.lastErrorText() + "\n";
    exit
end

json.put_EmitCompact(false)
print json.emit() + "\n";
