md5

I keep on reading on SO that MD5 is broken, bust, obsolete and never to be used. That angers me. The fact is that collision attacks on MD5 are now fairly easy. Some people have collision attacks down to an art and can even us use them to predict elections . I find most of the examples MD5 "brokeness" less interesting. Even the famous CA certificate hack was a collision attack meaning that its provable that the party generated the GOOD and EVIL certificates at same time. This means that if the EVIL CA found its way into the wild, it is provable that it leaked from the person who had the good CA

I created a test case which contains parameters that consist of key and value. I need to take all those parameters in an alphabetic order, and then create a MD5 hash value which i will pass to one of the parameters of this test. Any suggestions? i looked in google and cannot find anything helpful. Thanks ahead! You can retrieve the SoapUI's test case properties using a Groovy Script test step as given below. def map = context.testCase.properties.keySet().inject([:]){map, key -> map[key] = context.testCase.getPropertyValue(key); map } map.each { key, value -> log.info "Property name : ${key}

I need to calculate the checksum of a csv file. The checksum will change every time the data in the file is changed. I found nothing useful over the internet in this regard. First of all, this problem is not specific to JSP. JSP is just a HTML code generator. Writing Java code in a JSP file instead of a normal Java class doesn't make it a JSP problem. You would help yourself more if you concentrate on solving future Java problems using the "Java" keyword, not using the "JSP" keyword. Said that, you can just use MessageDigest which you update with the bytes read from the file. FileInputStream

I have a password stored in ldap as md5 hash: {MD5}3CydFlqyl/4AB5cY5ZmdEA== By the looks of it, it's base64 encoded. How can i convert byte array received from ldap to a nice readable md5-hash-style string like this: 1bc29b36f623ba82aaf6724fd3b16718 ? Is {MD5} a part of hash or ldap adds it and it should be deleted before decoding? I've tried to use commons base64 lib, but when i call it like this: String b = Base64.decodeBase64(a).toString(); It returns this - [B@24bf1f20 . Probably it's a wrong encoding, but when i convert it to UTF-8 i see unreadable chars. So, what can i do to solve this?

I have an existing database. users : username => varchar password => md5 hashing I am new to laravel, I was try to create simple login and register from laravel docs , thats work fine, but in docs are create for laravel, now I want to create same login/register but with existing datas. I was read some Question from How to use SHA1 encryption instead of BCrypt in Laravel 4? but I dont understand how to use it. any adv? sory for my bad grammer. I'll Try to answer my question. I take it from Facebook Group Laravel Indonesia Create directory app/libraries Add app/libraries to composer.json

I'd like to use gravatar in my iPhone application. Is there anyway to generate a hexadecimal MD5 hash in Objective-C for iPhone? Using openssl on iPhone is a no-go. This is how I did it before I removed it from my app: #import <CommonCrypto/CommonDigest.h> NSString* md5( NSString *str ) { const char *cStr = [str UTF8String]; unsigned char result[CC_MD5_DIGEST_LENGTH]; CC_MD5( cStr, strlen(cStr), result ); return [[NSString stringWithFormat:@"%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X", result[0], result[1], result[2], result[3], result[4], result[5], result[6], result[7],

I have a system where video files are ingested and then multiple CPU intensive tasks are started. As these tasks are computationally expensive I would like to skip processing a file if it has already been processed. Videos come from various sources so file names etc are not viable options. If I was using pictures I would compare the MD5 hash but on a 5GB - 40GB video this can take a long time to compute. To compare the 2 videos I am testing this method: check relevant metadata matches check length of file with ffmpeg / ffprobe use ffmpeg to extract frames at 100 predfined timestamps [1-100]

for some reasons I can't use MessageDigest.getInstance("MD5") , so I must write the algorithm code in manual way, my project is scan duplicate document (*.doc, *.txt, *.pdf) on Android device. My question is, what must I write before entering the algorithm, to scan the duplicate document on MY ROOT directory on Android device? Without select the directory, when I press button scan, the process begin, the listview show. Is anyone can help me? My project deadline will come. Thank you so much. public class MD5 { //What must I write here, so I allow to scan for duplicate document on Android root
