+node-multi-hashing
+===============
+
+Cryptocurrency hashing functions for node.js.
+Modified version by ocminer for use with xzc (zcoin) - lyra2rev2 is modified to only work with xzc
+
+Algorithms
+----------
+* quark
+* x11
+* x13
+* nist5
+* scrypt
+* scryptn
+* scryptjane
+* keccak
+* bcrypt
+* skein
+* groestl
+* blake
+* fugue
+* qubit
+* hefty1
+* shavite3
+
+Usage
+-----
+Use node v0.12+
+
+Install
+
+```bash
+npm install multi-hashing
+```
+
+So far this native Node.js addon can do the following hashing algos
+
+```javascript
+var multiHashing = require('multi-hashing');
+
+var algorithms = ['quark', 'x11', 'scrypt', 'scryptn', 'scryptjane', 'keccak', 'bcrypt', 'skein', 'blake'];
+
+var data = new Buffer("7000000001e980924e4e1109230383e66d62945ff8e749903bea4336755c00000000000051928aff1b4d72416173a8c3948159a09a73ac3bb556aa6bfbcad1a85da7f4c1d13350531e24031b939b9e2b", "hex");
+
+var hashedData = algorithms.map(function(algo){
+    if (algo === 'scryptjane'){
+        //scryptjane needs block.nTime and nChainStartTime (found in coin source)
+        var yaCoinChainStartTime = 1367991200;
+        var nTime = Math.round(Date.now() / 1000);
+        return multiHashing[algo](data, nTime, yaCoinChainStartTime);
+    }
+    else{
+        return multiHashing[algo](data);
+    }
+});
+
+
+console.log(hashedData);
