Methods for transferring messages ( 30 ) comprising extensible markup language information from sources ( 104 ) via intermediates ( 105 ) to destinations ( 106 ) are provided with hop-by-hop encryption/decryption processes instead of end-to-end encryption/decryption processes to reduce a complexity and to make non-encrypted messages ( 30 ) available inside the intermediates ( 105 ). The encryption/decryption processes are different per hop. An encryption/decryption of the message ( 30 ) comprises an encryption/decryption of one or more fields of the message ( 30 ) and may comprise an addition/detection of a signature. The message ( 30 ) may comprise a start envelope field ( 32 ), a header field ( 33 - 35 ), a body field ( 36 - 38 ) and a stop envelope field ( 39 ). The message ( 30 ) may comprise a simple object access protocol message or SOAP message.
