Is there any finite field arithmetic library for Go?

<p>I need to program some error-correction and cryptography (just for testing, it won&#39;t be deployed anywhere), but I don&#39;t want to waste time writing my own finite field arithmetic library. I tried to search for it, but couldn&#39;t find something specific. Is there any finite field arithmetic library for Go?</p> <hr/>**评论：**<br/><br/>smasher164: <pre><p>If you need operations over a Galois field, the crypto/cipher package implements the GCM mode. However looking at <a href="https://golang.org/src/crypto/cipher/gcm.go" rel="nofollow">gcm.go</a>, both <code>gcmFieldElement</code>and <code>productTable</code> are unexported.</p> <p>Otherwise, Russ Cox has an implementation of <a href="https://github.com/rsc/rsc/blob/master/gf256/gf256.go" rel="nofollow">GF(256)</a> that you should check out.</p></pre>theatrus: <pre><p>Look at the builtins. crypto/rsa uses math/big. </p></pre>
