sha1
====
[](http://travis-ci.org/pvorb/node-sha1) [](http://npm-stat.com/charts.html?package=sha1)
a native js function for hashing messages with the SHA-1 algorithm
Installation
------------
npm install sha1
or
ender build sha1
Example
-------
~~~ javascript
var sha1 = require('sha1');
sha1("message");
~~~
This will return the string:
"6f9b9af3cd6e8b8a73c2cdced37fe9f59226e27d"
API
---
### sha1(msg)
Returns the SHA-1 hash of the given message.
* `msg` String -- the message that you want to hash.
It's as simple as that.
### sha1(msg, options)
Returns the binary string or bytes array representation of SHA-1 hash for msg, based on options. There are two mutually exclusive option flags:
* `asString` true -- return binary string from digest bytes
* `asBytes` true -- return array of digest bytes
with empty options object, default output is hex-encoded string of digest bytes.
#### Examples
The following examples demonstate three possible outputs formats.
Get bytes array and put into buffer (straightforward):
~~~ javascript
var hash_bytes = sha1("message", {asBytes: true});
var result = new Buffer(hash_bytes);
~~~
Get binary string and decode into buffer as digest bytes:
~~~ javascript
var hash_binary = sha1("message", {asString: true});
var result = new Buffer(hash_binary, 'binary');
~~~
Get default hex-encoded output and decode into buffer as digest bytes:
~~~ javascript
var hash_text = sha1("message", {});
var result = new Buffer(hash_text, 'hex');
~~~
