Package ecdsa implements the Elliptic Curve Digital Signature Algorithm, as
defined in FIPS 186-3.
</p>
<p>
This implementation  derives the nonce from an AES-CTR CSPRNG keyed by
ChopMD(256, SHA2-512(priv.D || entropy || hash)). The CSPRNG key is IRO by
a result of Coron; the AES-CTR stream is IRO under standard assumptions.

			  The root nodes are the entry points of the

			  outside the package.
			  There may be non-exported or anonymous
			  functions among them if they are called
			  dynamically from another package.

			<p>
			  Click a node to visit that function's source code.
			  From there you can visit its callers by

			<h2 id="Sign">func <a href="http://localhost:6060/src/crypto/ecdsa/ecdsa.go?s=4284:4367#L137">Sign</a></h2>
			<pre>func Sign(rand <a href="../../io/index.html">io</a>.<a href="../../io/index.html#Reader">Reader</a>, priv *<a href="index.html#PrivateKey">PrivateKey</a>, hash []<a href="../../builtin/index.html#byte">byte</a>) (r, s *<a href="../../math/big/index.html">big</a>.<a href="../../math/big/index.html#Int">Int</a>, err <a href="../../builtin/index.html#error">error</a>)</pre>
			<p>
Sign signs an arbitrary length hash (which should be the result of hashing a
larger message) using the private key, priv. It returns the signature as a
pair of integers. The security of the private key depends on the entropy of
rand.
</p>

			
			<h2 id="Verify">func <a href="http://localhost:6060/src/crypto/ecdsa/ecdsa.go?s=5960:6020#L211">Verify</a></h2>
			<pre>func Verify(pub *<a href="index.html#PublicKey">PublicKey</a>, hash []<a href="../../builtin/index.html#byte">byte</a>, r, s *<a href="../../math/big/index.html">big</a>.<a href="../../math/big/index.html#Int">Int</a>) <a href="../../builtin/index.html#bool">bool</a></pre>
			<p>
Verify verifies the signature in r, s of hash using the public key, pub. Its
return value records whether the signature is valid.
</p>

			
			<h2 id="PrivateKey">type <a href="http://localhost:6060/src/crypto/ecdsa/ecdsa.go?s=1378:1427#L42">PrivateKey</a></h2>
			<pre>type PrivateKey struct {
    <a href="index.html#PublicKey">PublicKey</a>
    D *<a href="../../math/big/index.html">big</a>.<a href="../../math/big/index.html#Int">Int</a>
}</pre>
			<p>
PrivateKey represents a ECDSA private key.
</p>


				<h3 id="GenerateKey">func <a href="http://localhost:6060/src/crypto/ecdsa/ecdsa.go?s=2606:2686#L89">GenerateKey</a></h3>
				<pre>func GenerateKey(c <a href="../elliptic/index.html">elliptic</a>.<a href="../elliptic/index.html#Curve">Curve</a>, rand <a href="../../io/index.html">io</a>.<a href="../../io/index.html#Reader">Reader</a>) (priv *<a href="index.html#PrivateKey">PrivateKey</a>, err <a href="../../builtin/index.html#error">error</a>)</pre>
				<p>
GenerateKey generates a public and private key pair.
</p>

				
				<h3 id="PrivateKey.Public">func (*PrivateKey) <a href="http://localhost:6060/src/crypto/ecdsa/ecdsa.go?s=1532:1581#L52">Public</a></h3>
				<pre>func (priv *<a href="index.html#PrivateKey">PrivateKey</a>) Public() <a href="../index.html">crypto</a>.<a href="../index.html#PublicKey">PublicKey</a></pre>
				<p>
Public returns the public key corresponding to priv.
</p>

				
				<h3 id="PrivateKey.Sign">func (*PrivateKey) <a href="http://localhost:6060/src/crypto/ecdsa/ecdsa.go?s=1853:1949#L60">Sign</a></h3>
				<pre>func (priv *<a href="index.html#PrivateKey">PrivateKey</a>) Sign(rand <a href="../../io/index.html">io</a>.<a href="../../io/index.html#Reader">Reader</a>, msg []<a href="../../builtin/index.html#byte">byte</a>, opts <a href="../index.html">crypto</a>.<a href="../index.html#SignerOpts">SignerOpts</a>) ([]<a href="../../builtin/index.html#byte">byte</a>, <a href="../../builtin/index.html#error">error</a>)</pre>
				<p>
Sign signs msg with priv, reading randomness from rand. This method is
intended to support keys where the private part is kept in, for example, a
hardware module. Common uses should use the Sign function in this package
directly.
</p>

				
			<h2 id="PublicKey">type <a href="http://localhost:6060/src/crypto/ecdsa/ecdsa.go?s=1274:1330#L36">PublicKey</a></h2>
			<pre>type PublicKey struct {
    <a href="../elliptic/index.html">elliptic</a>.<a href="../elliptic/index.html#Curve">Curve</a>
    X, Y *<a href="../../math/big/index.html">big</a>.<a href="../../math/big/index.html#Int">Int</a>
}</pre>
			<p>
PublicKey represents an ECDSA public key.
