AS2

Overview

The abbreviation AS2 stands for a secure peer-to-peer transmission protocol for business data based on MIME (Multipurpose Internet Mail Extensions) using HTTP (Hypertext Transfer Protocol). AS2 is documented in detail in RFC 4130.

The most important AS2 features are:

  • Secure transmission of structured business data (in various formats such as XML, UN/EDIFACT, ANSI X.12, CSV, etc.) using the HTTP protocol.
  • Bi-directional active sending of messages
    • Each side uploads files to the other's server
    • No wait times due to polling intervals: message processing starts immediately after receiving a file.
    • The participants are always ready to receive data in order to be able to receive data from a partner: This behavior distinguishes AS2 fundamentally from mail systems.
  • Structuring of the transmitted data according to the MIME standard.
  • Authentication and encryption of the transmitted data according to S/MIME using private or public certificates.
  • Authenticated receipts are generated to the original HTTP messages as "MDN" (Message Disposition Notification) so that the sender of the data has positive confirmation having delivered them (MDNs are only generated upon request of the sender of data).

http://as2.edicc.de:5080/as2in (HTTP)

Also available:  ​https://as2.edicc.de:5081/as2in (HTTPS)
Encryption via HTTPS is not strictly required in AS2 since AS2 can already encrypt the entire message exchange and sign its payload anyways.

AS2-ID

AS 2 URL (Test)
e-integration uses the same URL for Test connections (see above); the AS2-ID serves as a differentiator (see below).
AS2-ID (Test)

EDICC-TEST

A note to our e-AS2 Connect customers:
since it is not possible to add EDICC-TEST as an additional partner profile, please create a directory EDICC-TEST in folder interface/out
This ensures that test data is sent our test system from this folder.

AS2 encryption
e-integration expects AES256-CBC (SHA-256) using our AS2 public key certificate.
Other options are accepted without further specification.

e-integration would like to encrypt AS2 data using AES256-CBC (SHA-256) encryption by default. 
Please provide your AS2 public key certificate to us to use for encryption.
AS2 signature
e-integration signs messages using SHA256withRSA (default).
​MDN Delivery Mode ​e-integration requests "synchronous MDN" by default.
File Compression ​e-integration automatically detects and handles compressed files.
By default, e-integration does not send compressed files.

Certificates and public key

To operate AS2, certificates and a public key must be installed.
On this site you will find all required files for download: ftp://eas2:geteas2@ftpcc.edicc.de/certificates

The files are named as follows: 

​Standard AS2 certificate
