+ "Optimized C library for EC operations on curve secp256k1.
+
+This library is a work in progress and is being used to research best
+practices. Use at your own risk.
+
+Features:
+
+@itemize
+@item secp256k1 ECDSA signing/verification and key generation.
+@item Adding/multiplying private/public keys.
+@item Serialization/parsing of private keys, public keys, signatures.
+@item Constant time, constant memory access signing and pubkey generation.
+@item Derandomized DSA (via RFC6979 or with a caller provided function.)
+@item Very efficient implementation.
