Overview

Dsco supports exchanging files via an AS2 server. This document details the technical requirements for connecting via an AS2 Server.

 

Dsco supports the AS2 transport protocol using its own AS2 server. Dsco's AS2 server must be configured to communicate with the partner's AS2 server. Likewise, the partner's AS2 server must be configured to communicate with Dsco's AS2 server.

Dsco requires that each file sent via AS2 have a unique file-name. If a file is transferred and has the same file-name as a previous file, we will not process it.

Dsco AS2 Server Configuration

A partner will need to create a connection in their own AS2 server with the following Dsco AS2 configuration information...

  • AS2 ID
    DscoExAs2
  • AS2 Receipt URL
    http://as2-5.dsco.io/as2/HttpReceiver
  • IP Addresses Your Firewall Must Accept
    34.206.59.225
  • Data encryption
    3DES
  • Digital signature
    SHA-2
  • Compression
    NO
  • Request sync MDN
    NO
  • Request signed MDN
    NO

Partner AS2 Server Configuration

The partner needs to send to Dsco, via an email to support@dsco.io, the following settings describing the partner's AS2 configuration. In addition, the partner should include their AS2 certificate and any special instructions around a self-signed cert.

  • AS2 ID
    <Please provide the partner AS2 ID>

    Each AS2 server is uniquely identified by a string of characters called the AS2 System Identifier - often referred to as the AS2 ID. The AS2 ID is a string of 1 to 128 ASCII characters and is case-sensitive. The AS2 ID identifies the sender and receiver in AS2 communication and determines which certificates will be used. There is no canonical registrar of AS2 IDs and, therefore, no guarantee that each ID will be unique.


  • AS2 Receipt URL
    <Please provide the partner AS2 Reciept URL>

    This is the URL which is used by external AS2 servers to communicate with the partner.


  • Data encryption
    <Please provide partner Data encryption, one of these value... 3DES, No Encryption, DES, RC2-40, RC2-64, RC2-128, RC2-196, RC4-40, RC4-56, RC4-128, AES-128, AES-192, AES-256>

    This is the algorithm the partner's AS2 server uses to encrypt the data.


  • Digital signature
    <Please provide partner Digitial signature, one of these values... No Signature, MD5, SHA-224, SHA-256, SHA-384, SHA-512>

    This is the algorith the partner's AS2 server uses to sign the data.


  • Compression
    <Please specify YES or NO>

    Whether or not the partner's AS2 server requests compression of the data.


  • Request sync MDN
    <Please specify YES or NO>

    Whether or not the partner's AS2 server requests synchronous MDN.


  • Request signed MDN
    <Please specify YES or NO>

    Whether or not the partner's AS2 server requests a MDN responses be signed.

Certificates

Please send an email to support@dsco.io that includes the partner's AS2 certificate and request the Dsco AS2 certificate. Dsco will respond to the email with its AS2 certificate and server information.
