Requirements AS2 Connector for .NET Core

The AS2 Connector sends and receives business messages and acknowledgments of receipt
in accordance with Applicability Statement 2 (AS2).


AS2 describes how business messages are exchanged securely over the HTTP protocol in a
peer-to-peer network. AS2 defines how the connection is established, how business
messages are validated, sent and confirmed with acknowledgments of receipt.


The authorship of a business message is guaranteed through digital signatures and data
security through encryption. The sender receives a digital receipt (Message Disposition
Notification, MDN) from the AS2 transmission standard, which the sender can use to prove
delivery on time.


Before sending, an envelope in the form of a standard MIME structure is generated for each
business message.


The business messages can be in an XML format, EDI format (e.g. ANSI X12 or UN /
EDIFACT), or in any other structured format.
See IETF-AS2 specification at rfc4130 (ietf.org)
