EDIINT AS2 implementation - certificates


we are planning to integrate with Sterling commerce VAN via AS2.
This would be our first AS2 implementation. we have a ssl certificate for our IS.

For the AS2 documents, we intend to sign and encrypt.

The question which I have is, can we use the same certificate (i.e the one which we have for our IS) also for AS2 signing and encryption OR
Do I have to use separate certificates for both.

Please advise.


You can use it and you will need to share the publickey(cert) to other partner as well for them to verify/decrypt
