This library is a partial implementation of the XML encryption standard. It implements the decryption part, which is needed by SAML clients.

[det]decrypt_xml(+DOMIn, -DOMOut, :KeyCallback, +Options)
KeyCallback may be called as follows:

  • call(KeyCallback, name, KeyName, Key)
  • call(KeyCallback, public_key, public_key(RSA), Key)
  • call(KeyCallback, certificate, Certificate, Key)

[det]load_certificate_from_base64_string(+String, -Certificate)
Loads a certificate from a string, adding newlines and header where appropriate so that OpenSSL 1.0.1+ will be able to parse it
