@NotMutable @ThreadSafety(level=COMPLETELY_THREADSAFE) public final class ASN1Sequence extends ASN1Element
This class provides an ASN.1 sequence element, which is used to hold an ordered set of zero or more other elements (potentially including additional "envelope" element types like other sequences and/or sets).

      Decodes the contents of the provided byte array as a sequence element.
      Parameters:
      elementBytes - The byte array to decode as an ASN.1 sequence element.
      Returns:
      The decoded ASN.1 sequence element.
      Throws:
