I know that this might be a long stretch, but could someone possibly tell me where my current implementation of the MD5 algorithm in PHP is going wrong? I just can't seem to work out what's wrong with it. It returns a 32 character hex string (25% of the time it produces a string less than 32 characters though), but it isn't producing th...
Hi, i want to know if exist a way to differentiate a md5 hashcode of a sha-1 hashcode? For example: d41d8cd98f00b204e9800998ecf8427e da39a3ee5e6b4b0d3255bfef95601890afd80709 How i could to know which are encrypted in md5 and wich not? Is it possible? ...
I am trying to input a text file that contains MD5 hashes and keywords (one per line) into a C# app. Is there a way to check if a string is an MD5 hash? I looked on MSDN and couldn't find anything in the MD5 class. ...
Hi, I am studying MD5 algorithm. I found out that there are four state variables (I am not sure what that means). Those variables are 0x67452301 , 0xEFCDAB89, 0x98BADCFE, and 0x10325476. I converted variables to decimals and came up with 1732584193, 4023233417, 2562383102, and 271733878 resepectively. my question is, why those numbers?...
This is a combinatorics question with some theory in hashing algorithms required. Let's say the input can be any random sequence of bytes 30 kB to 5 MB of size (I guess that makes quite a few combinations of input values :)) What is the probability that the first 4 bytes (or first n bytes) of a MD5 hash computed from the byte sequence ...
Im making a website that will intergrate with game that only support md5 hashing metod (atm). Which ofc is not especially safe anymore. But how could i make it stronger? Should I just generate long strings of random letters and numbers and hash them? But then the users have to save the password on a paper/txt file in computer. What do y...
Hi all, i would like to know padding process in md5 algorithm detail. ...
Hey Guys, I need to grab just the md5 value from a file and make it a variable which I can use to compare to another md5 value. The problem is this file looks like this: a7393f772e34ca16a5854e80d9ec6704 md5 How do I open the file and only grab the actual number in DOS? (Not the "md5" And set it as a variable? Thanks! ...
Hi, I am learning MD5. I found a term 'hash' in most description of MD5. I googled 'hash', but I could not find exact term of 'hash' in computer programming. Why are we using 'hash' in computer programming? What is origin of the word?? ...
Is making system call to "md5sum file1" and "md5sum file2" and compare two return values enough in this case? ...
Hello, I want to use md5() and crypt() together in php login authentication. I tried to use md5(crypt(string),salt); but i can't login in mysql. Does anyone know how to use them together? Thanks a lot. ...
I am not a security expert... so I might be very wrong here. Am I right in that the only advantage to using a stronger algorithm is to slow down password cracking? In which case they must have the password hash and so will have already comprimised my database right? As I do not store any thing of real world value what is the point in ...
For each of our binary assets we generate a MD5 hash. This is used to check whether a certain binary asset is already in our application. But is it possible that two different binary assets generate the same MD5 hast. So is it possible that two different strings generate the same MD5 hash? ...
In C# how we can use SHA1 automatically?Is SHA1 better than MD5?(We use hashing for user name and password and need speed for authentication) ...
hello all! I'm trying to validate a pair of data columns on mysql from my php page across md5 function. I've encrypted the string "helloworld" with php md5 function and attempted to compare it with MYSQL MD5 function but it won't work. I do this because in the database there is a pair of strings "hello" and "world" needs to be compared w...
What's the most efficient way to convert an md5 hash to a unique integer to perform a modulus operation? ...
The two data blocks are from this site,but failed to produce the collision : var_dump(md5('d131dd02c5e6eec4693d9a0698aff95c2fcab58712467eab4004583eb8fb7f8955ad340609f4b30283e488832571415a085125e8f7cdc99fd91dbdf280373c5bd8823e3156348f5bae6dacd436c919c6dd53e2b487da03fd02396306d248cda0e99f33420f577ee8ce54b67080a80d1ec69821bcb6a8839396f9652...
I'm creating a MySQL database with registered users, and I'm thinking to use md5 not only for passwords but for e-mails too. I think this choice can improve user security, but I'm not yet an expert with databases and I'm not sure if this is wise or not! I hope this isn't a stupid question! ...
I'm implementing an interface for digital payment service called Suomen Verkkomaksut. The information about the payment is sent to them via HTML form. To ensure that no one messes with the information during the transfer a MD5 hash is calculated at both ends with a special key that is not sent to them. My problem is that for some reason...
So as many of you may already know, CommonCrypto isn't included in the iPhone SDK anymore (as on 3.0). Where else can I easily get hold of an MD5 function? Am I going to have to compile OpenSSL into my project just to get MD5?? A few clarifications: This isn't for security This is going to be used with an API that requires an MD5 dig...
