Answer 5

Can you explain why you want a blank password, as opposed to one that is constant, or no encryption at all?  I mean, why not just use "BLANK", as probably 10% of computer users use for their passwords...

Answer 6

Hi,

     I want to use powerful algorithm without password key and also i want to encrypt and decrypt data. Base64 is basic level. And MD5 given does not have decrypt function.

Answer 7

Well, MD5 is not an encryption method, so there is no reason for it to offer a decrypt function.  A single MD5 does not have a single source that could have produced it.  Also, a powerful algorithm with a silly key is not powerful, in my opinion.
