+#: Turns ASN.1 object into DER octet stream.
+#:
+#: Takes any ASN.1 object (e.g. :py:class:`~pyasn1.type.base.PyAsn1Item` derivative)
+#: walks all its components recursively and produces a DER octet stream.
+#:
+#: Parameters
+#: ----------
+#: value: either a Python or pyasn1 object (e.g. :py:class:`~pyasn1.type.base.PyAsn1Item` derivative)
+#:     A Python or pyasn1 object to encode. If Python object is given, `asnSpec`
+#:     parameter is required to guide the encoding process.
+#:
+#: Keyword Args
+#: ------------
+#: asn1Spec:
+#:     Optional ASN.1 schema or value object e.g. :py:class:`~pyasn1.type.base.PyAsn1Item` derivative
+#:
+#: Returns
+#: -------
+#: : :py:class:`bytes`
+#:     Given ASN.1 object encoded into BER octet-stream
+#:
+#: Raises
+#: ------
+#: ~pyasn1.error.PyAsn1Error
+#:     On encoding errors

+#: Examples
+#: --------
+#: Encode Python value into DER with ASN.1 schema
+#:
+#: .. code-block:: pycon

+#:    >>> seq = SequenceOf(componentType=Integer())
