Exports a SHA1 function that uses node's crpyto module under the hood
npm install node-sha1Provides you with a convenient sha1 function that uses Node's crypto module
under the hood.
npm install node-sha1 --savejavascript
var sha1 = require('node-sha1');
sha1('Hello World!'); # 2ef7bde608ce5404e97d5f042f95f89f1c232871
`API
$3
Can be a string, buffer, or even a stream (stream requires a callback).
If what is a string, or a buffer the hash will be returned, if a callback
is registered it will also be called with the resulting hash.
If what is a stream, it will throw if a callback is not registered. Otherwise
it will call the callback with the resulting hash.
$3
any errors that occurred, or undefined if no errors occurred. hash is
the resulting hash. If a callback is registered it will be called with the
resulting hash regardless if a stream, string, or buffer is used.Examples
