Class MSOEEncryptionKeyPreference

java.lang.Object
  iaik.asn1.structures.AttributeValue
      iaik.smime.attributes.MSOEEncryptionKeyPreference

All Implemented Interfaces:

iaik.asn1.ASN1Type

public class MSOEEncryptionKeyPreference
extends iaik.asn1.structures.AttributeValue

The MSOEEncryptionKeyPreference attribute.

MSOEEncryptionKeyPreference is a private ("1.3.6.1.4.1.311.16.4") attribute that is required by some versions of Microsoft Outlook (e.g. Express) to recognize the encryption cert in a signed message of a sender using different certs for encryption and signing. The encryption cert can be announced by an IssuerAndSerialNumber:

 MSOEEncryptionKeyPreference ::= IssuerAndSerialNumber
 

When creating a MSOEEncryptionKeyPreference object specify the IssuerAndSerialNumber for the encryption certificate of the sender, e.g.:

 X509Certificate encyrptionCert = ...;
 IssuerAndSerialNumber ias = new IssuerAndSerialNumber(encryptionCert);
 MSOEEncryptionKeyPreference MSOEEncryptionKeyPreference = 
   new MSOEEncryptionKeyPreference(ias);
