Ext.util.MD5

[wm003]

i found this code years ago somewhere on the net and "ported" it to Ext...as it wasnt Part of the existing crypto Plugin that only contains SHA-1 (yes, i know SHA-1 is more secure because of 160-Bit instead of 128-Bit with MD5, but as MD5 is furthermore used in many applications and i needed it for my old and current projects, i hope this is useful for someone else also )

It works exactly like the PHP function md5()

[UPDATE 2008/03/20]
- added optional parameters for raw binary output of a 16 letter binary string instead of the 32 Bit hex-string
- moved the hexcase parameter as optional parameters to the function call (default to false=> lowercase)
- moved the charset parameter as optional parameters to the function call (default to 8=> ASCII)
- passes the jslint test now

Usage:
string Ext.util.MD5 ( string str [, bool raw_output ][, bool hexcase ][, number charset {8(ASCII):16(UNICODE)} ] )

[code]
var MD5Hash = Ext.util.MD5("testtext"); //returns 0ea2d99c9848117666c38abce16bb43e
var MD5Hash = Ext.util.MD5("testtext",false,true); //returns 0EA2D99C9848117666C38ABCE16BB43E
var MD5Hash = Ext.util.MD5("testtext",true); //returns binary string

Parts of this work are based upon work by "RSA Data Security, Inc. MD5 Message-Digest Algorithm"

Thank you very much for sharing. I already use some md5 function but I like your Ext-ish version more.

Any license or conditions of use?

As the algoryhtm is freely available here this piece of code can be used freely without any conditions by anyone using Ext

Awesome!
Useful tool.

Thanks!

Doing a "Qual Check" on files of my application, the Ext.util.MD5 is the part of, I found that running it through http://jslint.com spits out errors.

Could you please run it through jslint and fix these errors?

Done so. I updated my original post at the top.
The only thing jslint moans at least is that "Ext" has not been defined, what is ok here, as the function assumes "Ext.util" is still present.

Thanks for the code, you may want to post it under the extension section of the site. But this will be extremely helpful.

I'm using md5 javascript implementation for SASL Difest MD5
http://pajhome.org.uk/crypt/md5/

I'm using the functions

function hex_md5(s){ return binl2hex(core_md5(str2binl(s), s.length * chrsz));}
function str_md5(s){ return binl2str(core_md5(str2binl(s), s.length * chrsz));}

Is it possible to achieve the same with your extension?

If it isn't, could you extend it to use these functions?

Thanks

Super, thank you. BTW, if you put /*global Ext */ at the beginning of the file jslint is satisfied as he knows that you know about the global Ext.
