Re: Fwd: Hash for data in transit

You can hash the form data, then encrypt the hash with a shared transaction
key given to the user via a capcha type of method.

Basically you sign the form data using a capcha phrase as the random
shared per transaction key.  Just make sure the whole transaction uses
SSL/TLS of appropriate strength.

That would prove against tampering in transit, twice over.  Once via the
SSL/TLS and second via the internal signing.

Saleh,

Thanks for the feedback. Our team is still trying different things to comply with this
security requirement. Trying to find a solution to verify the integrity without opening
more vulnerabilities with the solution. Any additional suggestions are welcomed.

Thanks.
