Hash user password without User instance in symfony

好久不见. 提交于 2021-02-02 09:28:08
问题 As it can be read in the official documentation, the current procedure to manually hash a password in the Symfony framework, is the following: use Symfony\Component\Security\Core\Encoder\UserPasswordEncoderInterface; public function register(UserPasswordEncoderInterface $encoder) { // whatever *your* User object is $user = new App\Entity\User(); $plainPassword = 'ryanpass'; $encoded = $encoder->encodePassword($user, $plainPassword); $user->setPassword($encoded); } The encodePassword method

Storing a proc inside an array inside a hash

拟墨画扇 提交于 2021-01-29 18:19:39
问题 I am still working on my text adventure. I am having trouble with the use/with function. It is meant to call a Hash in which the key is the used object and the content includes an array; the first element in the array is the target object, and the second a Proc that will be executed if that relation turns to match the arguments for the use/with function. Please, may you clarify me how I can store a code block inside an array inside a hash so I can recall it later depending on the objects that

Delete files based on MD5 hash

感情迁移 提交于 2021-01-29 14:33:05
问题 Using Windows command line (not powershell), I want to hash all files within the directory and then remove files that match a particular hash set contained within a text file. I've considered using md5deep, but I'm unsure if the output of matched files can then be redirected into a delete command. Any help gratefully received, thank you! To add some detail; the files are in a directory called 'images' md5deep.exe -r -b -x irrelevant_hashes.txt c:\images This gives me a list of the files that

BLAKE2 input parameters

◇◆丶佛笑我妖孽 提交于 2021-01-29 08:22:09
问题 Being a newbie, I was reading papers on the recent crop of hash functions and BLAKE2 intrigued me. Then I wanted to play around with the "blake2s" code in the code package. If I were to implement a simple string hasher, I could understand that there are built-in variables for a key and salt. But I couldn't figure out how to provide a string or file as input and collect the hash as input. Which variable(s) are responsible for the message and the digest? Maybe I'm doing things wrong but the

Decrypting MD5 hashed text when salt is known

别说谁变了你拦得住时间么 提交于 2021-01-29 07:23:04
问题 Let's say I have the following MD5 hashed password: bec0932119f0b0dd192c3bb5e5984eec If I know that the original password was salted and hashed and know that instead of typical salt it was just wrapped in 'flag{}' before MD5 summing it. How may I decrypt MD5 in this case? 回答1: The other answer is not correct in the definition of what you are trying. Let's begin with the formal definitions of Cryptographical hash functions' required resistances. The below from Cryptographic Hash-Function

Regular expression to extract hashes from file

问题 I have a file in this format: 5:Name: {"hash":"c602720140e907d715a9b90da493036f","start":"2016-02-20","end":"2016-03-04"} 5:Name: {"hash":"e319b125d71c62ffd3714b9b679d0624","sa_forum":"on","start":"2015-11-14","end":"2016-02-20"} I am trying to extract the hash key and date using a regular expression. How can I do it? I tried this /^[a-z0-9]{32}$/ for the hash but it doesn't work. I would appreciate some help. Edit: This is a text file, and I'm trying to preg_match() it. Here's my code: $file

Deleting duplicate files if file exists in certain directories - python

与世无争的帅哥 提交于 2021-01-28 19:52:47
问题 I have 3 folders - 1 master and 2 supplemental. I am writing a script that identifies duplicate files in all three via SHA1 hashing. For any duplicates found in master and supplementals (or their subdirectories), I would like to delete the files in the supplemental folders and keep the files in the master folder. If duplicate files are found in the supplemental folders and not the master folder, I would like to keep them and eventually merge with the master. I have written a script (below)

Hash function issue - adding functionality

问题 I tried adding functionality to the djb2 hash function, but it doesn't appear to like the changes. Specifically, I'm trying to include a loop that converts words (strings) to lower case. It throws the following two errors: Incompatible integer to pointer conversion assigning to char * from int Cannot increment value of type char *[45] Note that in the original code *str++ appeared in the while loop. This is my first hash table, and I'm rather shaky on pointers. Any insight on where I've gone

How to authenticate user against salted and hashed password and username?

南笙酒味 提交于 2021-01-28 12:41:04
问题 I am developing a .net web api project and need to store usernames and passwords salted and hashed in a users table. How would I authenticate the user if the username and password fields are random hashed in the users table and the salts are stored in the same row for the user? Am I missing something? It seems as if I would have no way to find the user to do a password comparison. 回答1: They are not random hashed per se. They are hashed against the same key. As a result, to authenticate, you
