  - ### Method Detail

    - #### getInstance

          public static ASN1BitString getInstance​(java.lang.Object obj)

      return a Bit String that can be definite-length encoded from the passed in object.
      Parameters:
        `obj` - a DL or DER BitString or an object that can be converted into one.
      Returns:
        an ASN1BitString instance, or null.
      Throws:
        `java.lang.IllegalArgumentException` - if the object cannot be converted.

    - #### getInstance

          public static ASN1BitString getInstance​(ASN1TaggedObject obj,
                                                  boolean explicit)

      return a Bit String from a tagged object.
      Parameters:
        `obj` - the tagged object holding the object we want
        `explicit` - true if the object is meant to be explicitly tagged false otherwise.
      Returns:
        an ASN1BitString instance, or null.
      Throws:
        `java.lang.IllegalArgumentException` - if the tagged object cannot be converted.
