We can compare this to the block size of commonly used schemes and figure out what it cant be. This means that this block includes one useful piece of information, namely that the output is 16 bytes long. The fact that it is base 64 encoded doesnt tell us much because base 64 is not an encryptionhashing algorithm it is a way to encode binary data into text. That will also give you an extendeed list at blog20090414how-to-crack-md5-passwords.įor example, if you take any hash output and rotate each letter by 1, most pattern matching schemes will fail. If you are dealing with a closed-source binary application - check out. Regarding your experiments, Yes, this is a value stored for password verification.Īnd any 128-bit value, when encoded with Base64, yields such a sequence. Pls tell me more about how you confirmed its a Base64 encoding for a sequence of 16 bytes. You may want to try to compute MD5(username:password) or other similar variants, to see if you get a match. If this is a value stored for password verification (i.e.Īpplication code is incarnated in a tangible, fat way (executable files on a server, source code somewhere.) which is not, and cannot be, as much protected as a secret key can.
