+     "PyCryptodome is a self-contained Python package of low-level
+cryptographic primitives.  It's 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.
