How expensive is MD5 generation in .NET?
To interact with an external data feed I need to pass a rolling security key which has been MD5 hashed (every day we need to generate a new MD5 hashed key). I'm trading up whether or not to do it every time we call the external feed or not. I need to has a string of about 10 characters for the feed. It's for an ASP.NET (C#/ .NET 3.5) s...
Automatically generate MD5 and display.
On a page that automatically lists several small files (~100-500kb) that are contained in a specific folder, is there a way using VBScript to automatically generate MD5 hashes of each file and display it on the page? Cliff notes: Can I generate an MD5 hash of a file on the server machine? ...
File MD5 checksum
In this question is mentioned the wcrypt2. What I need is simply calculate the MD5 of a file. It would be perfect if I could calculate it without having to save it because it is a downloaded file in stream format. I would like to have the most straightforward way to do that. Thanks! ...
Make MD5 of All Words in Wordlist
Let say we have a Wordlist with words What i want to is to Genate Them to MD5 Hashes. (Have a 30gb Wordlist, i want to make All of they to MD5) I dont care which language. This say I have The Word "Test" in the wordlist So i want it in this format : test:098f6bcd4621d373cade4e832627b4f6 098f6bcd4621d373cade4e832627b4f6 = Test in...
Can you convert the output of php crypt() to valid MD5?
I have some strings that have been encrypted using the php function crypt() http://uk2.php.net/crypt The outputs look something like this: $1$Vf/.4.1.$CgCo33ebiHVuFhpwS.kMI0 $1$84..vD4.$Ps1PdaLWRoaiWDKCfjLyV1 $1$or1.RY4.$v3xo04v1yfB7JxDj1sC/J/ While I believe crypt() is using the MD5 algorithm, the outputs are not valid MD5 hashes. ...
Calculating MD5 of string from Microsoft Access
How do I calculate an MD5 of a string client side in Microsoft Access? ...
How would I get a Hash value of a users file with Javascript or Flash?
What I need to do is provide a file browser box on a web page where a user selects a file from their computer and, through javascript (or flash if necessary), some sort of Hash is returned such as CRC, MD5 or SHA1. I would prefer not to have to upload the entire file to the web server, as I expect some rather large files to be used in th...
Is there a CPAN module that digests a short string into a short number?
I need to create unique numerical ids for some short strings. some.domain.com -> 32423421 another.domain.com -> 23332423 yet.another.com -> 12131232 Is there a Perl CPAN module that will do something like this? I've tried using Digest::MD5 but the resulting numbers are too long: some.domain.com -> 29680057245717615035661393...
Does the hash algorithm used for password hashing affect rainbow table generation?
re question non-random-salt-for-password-hashes Mr Potato Head states that the use of md5 instead of SHA-512 makes generating rainbow tables easier? I'd have thought that once your rainbow table is generated that the algorithm used is irrelevant? It would make no difference to how you use the rainbow table to check for known hashs? An...
How to set the crypto key for Python's MD5 module?
What is the Python equivalent of following Perl code? hmac_md5_hex($login . "^" . $seq . "^" . $time . "^" . $amo . "^", $CryptoKey); The Python hashlib.md5 doesn't seem to take an "cryptographic key" argument. It only accepts 1 argument. ...
MD5 hash calculates differently on server
Hi Everyone, I am running some code that I have written in C which calls the md5 hashing functionality from a hashing library that someone else wrote (md5.c & md5.h). The odd behavior I have been seeing is: hashing working perfectly = I hash a string, and it comes out to the exact hash that I have verified it to be with multiple other...
MD5 Code Coverage
I'm currently implementing an MD5 hash algorithm based RSA data security code, in the UpdateData method there is a section which reads: mCount[0] += (length << 3); if (mCount[0] < (length << 3)) { mCount[1]++; } I'm trying at the moment to understand how the if statement could ever evaluate to true (the mCount[0] value is initial...
Trying to understand the MD5 algorithm
Hey! I am trying to do something in C with the MD5 (and latter trying to do something with the SHA1 algorithm). My main problem is that I never really did anything complex in C, just simple stuff (nothing like pointers to pointers or structs). I got the md5 algorithm here. I included the files md5.c and md5.h in my C project (using cod...
How to convert an MD5 hash to a string and use it as a file name
I am taking the MD5 hash of an image file and I want to use the hash as a filename. How do I convert the hash to a string that is valid filename? EDIT: toString() just gives "System.Byte[]" ...
What is the purpose of MD5 hash in downloading apps?
I have never checked and compared the MD5 hash to the real MD5 hash at programs homepages. Programs which I have downloaded have always worked. Is it possible that someone can put their own code during downloading? ...
How to calculate md5 hash of a file using javascript
Is there any way to calculate the md5 hash of a file before the upload to the server using javascript? ...
Is MD5 less secure than SHA et. al. in a practical sense?
I've seen a few questions and answers on SO suggesting that MD5 is less secure than something like SHA. My question is, Is this worth worrying about in my situation? Here's an example of how I'm using it: On the client side, I'm providing a "secure" checksum for a message by appending the current time and a password and then hashing ...
Computing MD5SUM of large files in C#
I am using following code to compute MD5SUM of a file - byte[] b = System.IO.File.ReadAllBytes(file); string sum = BitConverter.ToString(new MD5CryptoServiceProvider().ComputeHash(b)); This works fine normally, but if I encounter a large file (~1GB) - e.g. an iso image or a DVD VOB file - I get an Out of Memory exception. Though, I ...
Detecting Retweets using computationally inexpensive Python hashing algorithms
In order to be able to detect RT of a particular tweet, I plan to store hashes of each formatted tweet in the database. What hashing algorithm should I use. Cryptic is of course not essential. Just a minimal way of storing a data as something which can then be compared if it is the same, in an efficient way. My first attempt at this wa...
