        return this.getString().equals(((DERUniversalString)o).getString());
public static org.bouncycastle.asn1.DERUniversalStringgetInstance(java.lang.Object obj)
return a Universal String from the passed in object.

exception
IllegalArgumentException if the object cannot be converted.

public static org.bouncycastle.asn1.DERUniversalStringgetInstance(ASN1TaggedObject obj, boolean explicit)
return a Universal String from a tagged object.

param
obj the tagged object holding the object we want
param
explicit true if the object is meant to be explicitly tagged false otherwise.
exception
IllegalArgumentException if the tagged object cannot be converted.

        return getInstance(obj.getObject());

        return string;
public java.lang.StringgetString()
UniversalStrings have characters which are 4 bytes long - for the moment we just return them in Hex...
