Trying to decode 128bit or 256 bit string?

the password string is some kind of like that

MT开发者_JAVA技巧Y5LTYtNjEtMjAxLTkwLTE3MS05My0yMDAtMTMxLTE5Mi01My0xNjItMC0yMjAtMTgxLTIyNg==

I tried base 64 encoder and it gives me:

169-6-61-201-90-171-93-200-131-192-53-162-0-220-181-226

Looks like encode by ASCII Code

I put the numbers on ASCII code list gives me :

©=ÉZ«]ȃÀ5¢Üµâ

But this not the password that i looked. Does anyone know the solution. I am not an expert sorry for bad explaining.

The string contains 16 numbergroups and each number is between 0 and 255. So it looks like 16 bytes. And 16 bytes / 128 bits is the size of an md5 hash. So that would be my guess.

While a crypto hash function can't be easily reversed, there are online rainbowtable services which can revert them for short or common inputs. But if the programmer who wrote it did it right (used a salt and many iterations) they won't help.

I'd split it in 16 numbers, than convert these to a byte array of size 16, and then hexencode them, since that's the form most programs will accept. Edit: See Kenny's comment
And then search for some website which allows search in rainbow tables. And pray...
