+
+Package ecdsa provides secp256k1-optimized ECDSA signing and verification.
+
+This package provides data structures and functions necessary to produce and
+verify deterministic canonical signatures in accordance with RFC6979 and
+BIP0062, optimized specifically for the secp256k1 curve using the Elliptic Curve
+Digital Signature Algorithm (ECDSA), as defined in FIPS 186-3. See
+https://www.secg.org/sec2-v2.pdf (also found here
+at [sec2-v2.pdf](../sec2-v2.pdf)) for details on the secp256k1 standard.
+
+It also provides functions to parse and serialize the ECDSA signatures with the
+more strict Distinguished Encoding Rules (DER) of ISO/IEC 8825-1 and some
+additional restrictions specific to secp256k1.
+
+In addition, it supports a custom "compact" signature format which allows
+efficient recovery of the public key from a given valid signature and message
+hash combination.
+
+A comprehensive suite of tests is provided to ensure proper functionality.
