What's the kind of password ?
It's not challenge ! It's the password that I hacked , but I don't know what the kind of it . And I also want to know : how can we know what kind of the the specific password ?
easy, it appears to be some form of Base 64 encoding. the '==' is a dead give away Can you show me more clear ? How can I crack it ?
Grindordie: Thats not encryption, thats encoding. the only true form of encryption is the stuff that you find in /etc/shadow. all that other stuff (including file "encrypted with digest functions, (a)symmetric ciphers etc) is just encoding. Why? because you can reverse it if you have the keys (sorry to correct you like that, but stuff liek that just bugs me :P )
okay, back to Base 64. You can tell that its Base 64 because it has the '==' on the end. thats a dead giveaway. http://www.snarkles.net has a Base 64 encoder/decoder. Now, this my be an MD5 or SHA-1 Binary digest ecoded with Base64 (thats somewhat common). So, if all you get is garbage when you try and decrypt it, thats why.
Basic PHP decryption: <?= base64_decode('BTIFN1Q1V2gANQB2W2FZMg=='); ?>
Which returned: 27T5Wh
And since each of the values arn't visible, this is what they map out to: 5, 50, 5, 55, 84, 53, 87, 104, 0, 53, 0, 118, 91, 97, 89, 50
press Alt+number for each of the above to view the string
Just out of curiosity, what site did you get this from?
