+%description
+PyCryptodome is a self-contained Python package of low-level
+cryptographic primitives.
+It supports Python 2.6 and 2.7, Python 3.4 and newer, and PyPy.
+You can install it with::
+    pip install pycryptodome
+All modules are installed under the ``Crypto`` package.
+Check the pycryptodomex_ project for the equivalent library that
+works under the ``Cryptodome`` package.
+PyCryptodome is a fork of PyCrypto. It brings several enhancements
+with respect to the last official version of PyCrypto (2.6.1),
+for instance:
+* Authenticated encryption modes (GCM, CCM, EAX, SIV, OCB)
+* Accelerated AES on Intel platforms via AES-NI
+* First class support for PyPy
+* Elliptic curves cryptography (NIST P-256, P-384 and P-521 curves only)
+* Better and more compact API (`nonce` and `iv` attributes for ciphers,
+  automatic generation of random nonces and IVs, simplified CTR cipher mode,
+  and more)
+* SHA-3 (including SHAKE XOFs) and BLAKE2 hash algorithms
+* Salsa20 and ChaCha20 stream ciphers
+* scrypt and HKDF
+* Deterministic (EC)DSA
+* Password-protected PKCS#8 key containers
+* Shamir's Secret Sharing scheme
+* Random numbers get sourced directly from the OS (and not from a CSPRNG in userspace)
+* Simplified install process, including better support for Windows
+* Cleaner RSA and DSA key generation (largely based on FIPS 186-4)
+* Major clean ups and simplification of the code base
+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.
+For more information, see the `homepage`_.
+All the code can be downloaded from `GitHub`_.
