Hi,
I want to use SOAP header as a tool for implementing secure web service. However, I have been told that when I send user credentials across the Internet via SOAP headers, they will be sent as a plain text in XML format, ie. they are vulnerable to prying eyes. One method to get around this is to encrypt the user credentials prior to sending them and provide an equivalent decryption algorithm in the web service. where can I find examples ( codes in Vb)or articles that can help me to solve this type of problem????????

Thanks
