I want to calculate md5 hash codes from strings in a playgroundbook,but i got this error message, but i included it as this way:
I can not use these: CC_MD5, CC_LONG, CC_MD5_DIGES_LENGTH etc,etc.
The "same" file was downloaded twice with a different filename. Then their
md5 were computed but it was different. It seems the metadata (creation date) or possibly filename? are being used to compute the hash.
I am using
md5 command, on macOS.
EDIT: downvotes? what's wrong with the question.
testing out and learning about md5 brute force attacks and here is the problem:
Given a hexadecimal md5 hash value (a 4-byte array that was hashed using the md5 hash function), I need to write a brute-force C program which utilizes openssl. Problem statement: program should find the 4-byte value that was hashed (each of the 4 bytes correspond to an unsigned char in c). Program should search through all 4-byte arrays.
Since I am new to C and openssl, any suggestions on how I can get started in writing the code - any code sample to get me started?
I understand I need to go through combinations of characters and compare the hash value, but how do I setup the code to go through all the ASCII characters until it finds the one that matches the given hash value?
Any suggestion/direction would be great! Thanks in advance!
I'm just looking for an old system, and after deploying the system on my computer for testing, I see something I cannot explain.
if I run
echo md5('test') in the
index.html this gives me
but if I run and submit form and let the file that handles the input
echo md5(<input>) from the
form.php another hash is generated
this messes with the authentication on the login, and therefore am unable to login into the old system, as the
md5 hash of the password is not
Any idea on what could be wrong? I'm guessing some Unicode thingie?
The kicker is, it works on the deployment machine.
I am using as3corelib's MD5 has function from adobe.
I am hashing a 3mb file, this is taking around 6 seconds on decent hardware.
I must find a much faster way of creating a hash.
Am I correct in assuming that its slow because its running inside the actionscript virtual machine?
Do any ways exist to speed it up?
I am really looking for minimum possible security and so if some more simple hash method exists and was faster this may be a solution.
