+* ``urlsafe_base64_encode``: URL-safe Base64 encoding (``urlsafe_b64encode``)
+* ``urlsafe_base64_decode``: URL-safe Base64 decoding (``urlsafe_b64decode``)
+* ``base32_encode``: Base32 encoding (``b32encode``)
+* ``base32_decode``: Base32 decoding (``b32decode``)
+* ``base16_encode``: Base16/hex encoding (``b16encode``)
