+%description
+This is an easy-to-use implementation of ECDSA cryptography (Elliptic Curve
+Digital Signature Algorithm), implemented purely in Python, released under 
+the MIT license. With this library, you can quickly create keypairs (signing
+ key and verifying key), sign messages, and verify the signatures. The keys 
+and signatures are very short, making them easy to handle and incorporate 
+into other protocols.
