md5

问题 After updating ruby and rubyenv packages I'm facing an error. The libcrypto library is not loaded. When executing the suggested command it seems that it is searching for openssl in ruby /Users/User/.rvm/rubies/ruby-2.4.1 . But on my system I use /usr/local/Cellar/ruby/2.6.5 . $ gem pristine executable-hooks --version 1.3.2 Error loading RubyGems plugin "/Users/User/.rvm/gems/ruby-2.4.1@global/gems/gem-wrappers-1.2.7/lib/rubygems_plugin.rb": dlopen(/Users/User/.rvm/rubies/ruby-2.4.1/lib/ruby/2

问题 I wanted to do MD5 check when I download file from GCS. However, it seems that I didn't get the correct MD5 my on side..... One example s that got : local 1B2M2Y8AsgTpgAmY7PhCfg==, cloud JWSLJAR+M3krp1RiOAJzOw== But I'm pretty sure the file isn't corrupted... The following code are with C#7.0, using System.Security.Cryptography; using (var memStream = new MemoryStream()) { _StorageClient.DownloadObject(bucketName, gcsObj.Name, memStream); try { using (var md5 = MD5.Create()) { var hash = md5

问题 I'm trying to fix things on a PHP site. There is a pair of PHP functions: function get_rnd_iv($iv_len) { $iv = ''; while ($iv_len-- > 0) { $iv .= chr(mt_rand() & 0xff); } return $iv; } function md5_encrypt($plain_text, $password, $iv_len = 16) { $plain_text .= "\x13"; $n = strlen($plain_text); if ($n % 16) $plain_text .= str_repeat("\0", 16 - ($n % 16)); $i = 0; $enc_text = get_rnd_iv($iv_len); $iv = substr($password ^ $enc_text, 0, 512); while ($i < $n) { $block = substr($plain_text, $i, 16)

问题 I am trying to MD5 a string in ActionScript using the MD5 algorithm that was created by Adobe and is part of AS3corelib. (http://as3corelib.googlecode.com/svn/trunk/src/com/adobe/crypto/MD5.as). I am comparing this to an MD5 created in php that I know is correct. If I create MD5s using AS and PHP for say a string like "abcd1234" they both are equal, as is to be expected. The problem is, when my string contains some hexadecimal in it ie "abcd\x28\xBF\x4E", the MD5s from ActionSCript and php

问题 I'm storing my passwords on a server, and, using nothing but HTML/JavaScript, I need to be able to take an input password, compute the hash, then compare against what's in my database via Ajax. As I'm using CouchDB, there's actually no server code, which is where I'd normally do such a calculation. Any kind of one way encryption would work. I saw an old plugin that appears unsupported for an earlier version of jQuery. As 1.3 and 1.2 seem to be mostly incompatible from my experience, I wonder

问题 This Swift code (based on another post here on Stack Overflow) computes ten million MD5 hashes (and does nothing with them, for the sake of this example). But the md5() function leaks memory; the longer it runs, the more memory it consumes: import Foundation func md5(string: String) -> [UInt8] { var digest = [UInt8](count: Int(CC_MD5_DIGEST_LENGTH), repeatedValue: 0) if let data = string.dataUsingEncoding(NSUTF8StringEncoding) { CC_MD5(data.bytes, CC_LONG(data.length), &digest) } return

问题 I have recently started work in scala, and am required to create an implementation of MD5. It is my understanding that MD5 requires unsigned types, which scala does not come with. As I will soon begin Chisel, which does have unsigned types, I decided to implement its library. Everything appears good so far, except when doing the below bitwise operations, my F value becomes -271733879, which causes an error "Caused by: java.lang.IllegalArgumentException: requirement failed: UInt literal

问题 I need to know the cost of succeeding with a Preimage attack ("In cryptography, a preimage attack on a cryptographic hash is an attempt to find a message that has a specific hash value.", Wikipedia). The message I want to hash consists of six digits (the date of birth), then four random digits. This is a social security number. Is there also a possibility to hash something using a specific password. This would introduce another layer of security as one would have to know the password in order

问题 I'm working on decrypting something I didn't create. The authors encrypted it from a java program, and I'm trying to decrypt it in C#. They have given me the logic behind their encryption (the integer key array, encoding type, and TripleDES), and I've been trying to figure this out. Long story short, I have been able to decrypt most of the text, however, the middle is always scrambled. I've researched this a lot trying to figure it out, notably, the issue of Java's negative byte numbers. This

问题 All of my application is written in PHP, bar 1 script which happens to create a md5 hash which is used later via PHP scripts. Problem being they dont match up. PERL: #$linkTrue = 'http://www.themobilemakeover.co.uk/mobile-makeover-appointment-booking-signup.php' md5_hex($linkTrue); And for testing purposes i did this in PHP: echo md5("http://www.themobilemakeover.co.uk/mobile-makeover-appointment-booking-signup.php"); both return different values. Does anyone know why this is? EDIT: WHOLE PHP
