=== Hashing === | |||
SHA 256 hashes are handy for storing passwords and generating checksums (among other uses) | |||
Example code: | |||
<pre class="brush:js;toolbar:false;"> | |||
var myPassword = "5ekr3tPa55w0rd"; | |||
window.cipher.hash.SHA256(myPassword, function callback(aHash) { | |||
myApp.doSomethingWithAHash(aHash); | |||
}); | |||
</pre> | </pre> | ||
// Another idea: generating a file checksum in conjunction with the FileAPI | |||
