    I use Windows Authentication. I don't presume to know more. I said there would be colissions; you want to quibble about the number.

    And how do you think Windows stores your password? :rolleyes:

    Passwords Technical Overview[^]:

    For use in Windows networking, including Active Directory domains, the password is stored two different ways by default: as the LAN Manager one-way function (LM OWF) and as the NT OWF. "One-way function" is a term that denotes a one-way mathematical transformation of data. ... The most common type of one-way function in use is a cryptographic hash.

    Although interestingly, Microsoft have added to the confusion by referring to "encryption" in the same sentence.

      The only thing I'm confirming is that some people don't understand the difference between encrypting and hashing. :laugh: security - Fundamental difference between Hashing and Encryption algorithms - Stack Overflow[^]

        In this case, I don't care and don't need to know.

              I'm with Richard. It does not appear that you are using the same understanding that others have.

              There are two kinds of people in the world: those who can extrapolate from incomplete data. There are only 10 types of people in the world, those who understand binary and those who don't.

                You (speaking rhetorically) fixate on one technique / application and categorize a whole branch. Hashing as a technique "in" an "encryption situation"; it is only a footnote in applied cryptology ... usually with a sidebar to the effect of " ... but one only had to alter the last bit to etc. ...". If you really want to educate yourself on hashing, learn about the various ways to defeat hashing. I just thought the original question made about as much sense as asking what is the difference between a BMW and "an automobile" (which is confirmed by the length of the thread).

                    In general terms, yes, "hashing" has a wider meaning than "a cryptographic hash function". In the context of the original question, I think it's reasonable to assume that the OP was referring to "a cryptographic hash function", and not any of the other possible meanings. But given the OP's history as a help vampire, and the fact that he could have answered his own question by spending five minutes in Google, I also think it's reasonable to ignore the question, or direct him to Google. :)

                      My point is always to get the "OP" to clarify their OWN question. The fact that everyone needs to jump in an "reinterpret" my intentions is their problem. The fact that I am not always "obvious" about it, is also not my problem.

                        1. please some one tell me difference between hashing or encryption a data. 2) i saw hashing also encrypt data which is not human readable and encryption does the same then why people think hashing is different from encryption ? 3) what hashing does ? 4) if we encrypt data then we can decrypt it too but if we hashing the data then can we reverse the process ? 5) if no then what algorithm hashing use that no one can reverse the data ? 6) give me two sample code to has data one will hash data without salt key and another one hash data with salt key. thanks
