salt

I am trying to use PKCS5_PBKDF2_HMAC_SHA1() and below is my sample program. I wanted to make sure if my result of PKCS5_PBKDF2_HMAC_SHA1() is correct so I verified the same with the website http://anandam.name/pbkdf2/ and I see a different result. Am I using the API correctly? I am having doubts if I am passing salt value correctly. I have pasted my result and website result after the program. Please help me understand this. #include <stdio.h> #include <types.h> #include <string.h> #include <stdio.h> #include <stdlib.h> #include <malloc.h> #include <openssl/hmac.h> #include <openssl/evp.h>

Consider an ASP.NET MVC application using the Salt parameter in the [ValidateAntiForgeryToken] directive. The scenario is such that the app will be used by many customers. It's not terribly desirable to have the Salt known at compile time. The current strategy is to locate the Salt value in the web.config. [ValidateAntiForgeryToken(Salt = Config.AppSalt)] //Config.AppSalt is a static property that reads the web.config. This leads to a compile-time exception suggesting that the Salt must be a const at compile time. An attribute argument must be a constant expression, typeof expression or array

I am using WebMatrix and have built a website based on the "StarterSite". In this starter site you get a nice basic layout - including registration, login, forgot password pages etc... I've noticed that in the database that the "webpages_Membership" table has a column named "PasswordSalt". After creating a few new user accounts, this column always remains blank. So I'm assuming that no password salt (not even a default one) is in use. Obviously this is not the best practice, however I cannot seem to find any documentation that tells me how to set or manage the password salt. How can I set the

I have read the information provided on the PHP Manual Entry for crypt() , but I find myself still unsure of the format for a salt to trigger the Blowfish algorithm. According manual entry, I should use '$2$' or '$2a$' as the start of a 16 character string. However, in the example given later, they use a much longer string: ' $2a$07$usesomesillystringforsalt$ ', which indicates to me that whatever string I provide will be sliced and diced to fit the model. The problem I am encountering is actually triggering the Blowfish algo vs STD_DES . Example: $foo = 'foo'; $salt = '$2a$' . hash('whirlpool

I have been searching around and I am still unsure of what a "salt" is and how to use/implement it. Sorry for the noobish question, I am self learning php. Approximately Linear I am definitely not an expert, but the really short answer is that "salting" a line of text means to stick a few extra characters on the end of it. You could salt "salt" with "abcdefg" to get "saltabcdefg". This might be useful if "salt" happens to be a password that you'd like to make more difficult to guess. Typically, the password+salt are transformed ('hashed') by some difficult-to-reverse process into a completely
