password encoding: string to hex and back

Hi,

I am writing an application that requires a username and password input via a WebDynpro UI.

I would like to convert this data to a hexadecimal format during passing these value to the API function

that needs them. And convert them back to string format just before calling the target API function.

This would at least prevent displaying the password in plain text in the debugger, which would be a dramatic security issue.

Any idea's?

kind regards,

Sahla
