Ever hear of FirstClass E-mail client?

I was just doing some research, and was hoping I could figure out the algorithm done to encrypt the MD5 Hash passwords... Any idea's on how to go about doing so? I've done a few things trying for figure out patterens..ect and haven't really come up with much.

I do know...

It's Min/Maximum character limit is 32 characters once encrypted.
The characters value only goes from a-f, 0-9...ect.

I did come up with this list... so if any of you see a pattern let me know.

Help is appreciated!

md5() ?

[Dale]

?

[rabbit]

md5 isn't an encryption, it's a hash.  In most languages (like C and Java), it's a function in a library, but in others (PHP, ASP, etc...) it's a built in function: http://us2.php.net/md5

It's a hash, and you cannot decrypt it.

I do know...

It's Min/Maximum character limit is 32 characters once encrypted.
The characters value only goes from a-f, 0-9...ect.

Actually, it's 16 characters written in hex.

Shit, k.

Thanks guys.

Are you sure?  I'm pretty sure hexMD5 is 128-bit, which would make it 16 bytes long, which is 32 hex characters....

Hex is 128-bit?  So what do we do to print a SHA1 digest in human readable form?  Encode it in base64?

Blah, MD5.  It was late
