+PyCryptodome is a self-contained Python package of low-level cryptographic
+primitives.  It supports Python 2.6 or newer, all Python 3 versions and PyPy.
+PyCryptodome is a fork of PyCrypto.
+
+PyCryptodome is not a wrapper to a separate C library like OpenSSL.  To the
+largest possible extent, algorithms are implemented in pure Python.  Only the
+pieces that are extremely critical to performance (e.g. block ciphers) are
+implemented as C extensions.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
