Encrypt a JWE with a Password (PBES2)

See more JSON Web Encryption (JWE) Examples

Demonstrates Jwe.SetPassword, which sets the PBES2 password for a recipient. The example uses PBES2-HS256+A128KW key management with AES-128-GCM content encryption.

require 'chilkat'

success = false

jwe = Chilkat::CkJwe.new()

#  Protected header: PBES2 password-based key management with AES-128-GCM content encryption.
header = Chilkat::CkJsonObject.new()
header.UpdateString("alg","PBES2-HS256+A128KW")
header.UpdateString("enc","A128GCM")
success = jwe.SetProtectedHeader(header)
if (success == false)
    print jwe.lastErrorText() + "\n";
    exit
end

#  Set the PBES2 password for recipient 0.  The password should come from a secure source rather than
#  being hard-coded.
password = "myPassword"
success = jwe.SetPassword(0,password)
if (success == false)
    print jwe.lastErrorText() + "\n";
    exit
end

jweCompact = jwe.encrypt("This is the secret content.","utf-8")
if (jwe.get_LastMethodSuccess() == false)
    print jwe.lastErrorText() + "\n";
    exit
end

print jweCompact + "\n";
