md5

Is it possible to create a MD5 collision based on a known input value? So for example I have input string abc with MD5 900150983cd24fb0d6963f7d28e17f72 . Now I want to add bytes to string def to get the same MD5 900150983cd24fb0d6963f7d28e17f72 . (I know this is possible by bruteforcing and waiting a long time; I want to know if there is a more efficient way in doing this) mata Unitl now no algorithm has been discovered that allows you to find a matching input that will generate a given md5 hash. What has been proven is that you can create md5 collisions quite easily, for example with what is

Have simple Spring Security webapp with password encoding: <security:authentication-manager alias="authenticationManager"> <security:authentication-provider user-service-ref="personService"> <security:password-encoder hash="md5" ref="passwordEncoder"> <!-- <security:salt-source user-property="username"/> --> </security:password-encoder> </security:authentication-provider> </security:authentication-manager> Encoding also simple: person.setPassword(encoder.encodePassword(person.getPassword(), null)); So in DataBase all passwords will be encoded. Now I want to do authentication of some user with

python3.x已经把md5 module移除了。要想用md5得用hashlib module,以下是帮助手册中给的标准调用 import hashlib m = hashlib.md5() m.update(b"Nobody inspects the spammish repetition") #参数必须是byte类型，否则报Unicode-objects must be encoded before hashing错误 md5value = m.hexdigest() print(md5value) #bb649c83dd1ea5c9d9dec9a18df0ffe9 其实可简写，如下面的md5的例子，hashlib.md5(data)，就可以了 但是对中文字符串md5怎么办？ 中文字符在Python中是以unicode存在的,同一个字符串在不同的编码体系下有不同的值,所以在hash前要进行编码，个人建议转为gb2312,因为对比发现，我下载的一个工具算出的md5值是与gb2312编码后算出的md5值一样。（！网上md5的工具很多，是不是所有的md5工具都是这样的，未去考证，有兴趣的可以研究一下） import hashlib data='我是' m = hashlib.md5(data.encode(encoding='gb2312')) print(m.hexdigest(

Suppose you wanted to make a file hosting site for people to upload their files and send a link to their friends to retrieve it later and you want to insure files are duplicated where we store them, is PHP's sha1_file good enough for the task? Is there any reason to not use md5_file instead? For the frontend, it'll be obscured using the original file name store in a database but some additional concerns would be if this would reveal anything about the original poster. Does a file inherit any meta information with it like last modified or who posted it or is this stuff based in the file system?

I am working on an Android word game with a large dictionary - The words (over 700 000) are kept as separate lines in a text file (and then put in an SQLite database). To keep competitors from extracting my dictionary, I'd like to encode all words which are longer than 3 chars with md5. (I don't obfuscate short words and words with rare Russian letters ъ and э , because I'd like to list them in my app). So here is my script which I try to run with perl v5.18.2 on Mac Yosemite: #!/usr/bin/perl -w use strict; use utf8; use Digest::MD5 qw(md5_hex); binmode(STDIN, ":utf8"); #binmode(STDOUT, ":raw"

I need display in web page fingerprints of SSL Certificate. Is it possible in PHP? The function openssl_x509_parse doesn't return SHA1 and MD5 fingerprints. How resolve this problem? Thanks. I'd guess the easiest way is going to be to call openssl through system $fingerprint = str_replace("SHA1 Fingerprint=", '', system('openssl x509 -noout -in /path/to/your/cert.pem -fingerprint')); And yes, I know, this is nothing like a clean way of doing this - however, it's the only one I can think of of the top of my head!!! I think you can generate the SHA fingerprint with the following code: $resource

I'm trying to set up a login system, but I can't solve one problem: PHP is giving me an other output with md5(); than MySQL... For example, in PHP: $password = md5("brickmasterj"); return $password; Returns: 3aa7b18f304e2e2a088cfd197351cfa8 But the MySQL equivalent gives me a shorter version: 3aa7b18f304e2e2a08 What's the problem? And how do I work with this while checking passwords? I guess the problem in the length of column of your table, set the length of password field to at least 32 No way MySQL returns it of a length of < 32. If you would do a simple query like SELECT md5('brickmasterj'
