IS it possible to put digital signature on PDF/Docs using PI

[Former Member]

Hello,

I know to send mail using sign and encrypt.

Is it possible to sign(appending signature/logo) to the docs received into PI and send it to the customer or other applications..

Your replies will be helpful

PS : I have searched SDN for same stuff and not able to arrive at a conclusion for proceeding further

Are you planning to use ADS with PI? Haven't tried but i think with ADS it is possible.

Will that be different ...

Rajesh, this seems promising.

You may use the Cryptographic toolkit as mentioned in the doc and add this code in java mapping or module chain to achieve signing. You have the source. Why not give it a try?

Thank you for suggestions.

Thing making me dumb here is as keystore will have only certificate related data (private key/public key)

from where will i get the signature to be included in the message ?

Also can the existant code be implemented using either UDF or java Class?

Please let me know.

The example provided is using SSF mechanism to sign the data. You may have to use a third party tool for this but it shold be available for free as far as only signing is concerned.

UDF doesnt seem to be a poosible option. But as I said earlier, java mapping or adapter module could be used.

Hi Rajesh

Have you been able to achieve the same. I have similar requirement whereby i need to send pdf's that are digitally signed to an external business partner.
