Does EWB have a Delphi compatible hash function built in?
Something like MD5. I ask because I need to send a password from the client app to
the server, and obviously don't want to send it "raw". But I also need to know it
will be compatible at the Delphi server end.

(My app will be used at a University, so watching the wire and time to spend
hacking will be in plenty of supply.)

After reading more here, I wonder if I shouldn't use the encryption on RemObjects.
Anyone know if the JavaScript interface supports such?

Hmm, seems the (not really very much documented) RO SDK for JavaScript doesn't do
encryption. Hash in EWB it is then...

Hi Matthew - this might be of interest. Haven't used it yet myself though.

Thank you. I presume that this can be referenced using the external code facility?
And more important, the LGPL - does that have any effect on my code if I put this
in it, or if I put this code in an external file.

Matthew,

Yep, just use this declaration (case-sensitive):

external function sha1Hash(const msg: String): String;

and make sure to include the .js file in the project's external code files.

That, I do not know so I'll have to punt.
