golang equivalent of PHP crypt()

阅读更多关于 golang equivalent of PHP crypt()

This line of code in PHP evaluates to true echo '$2a$09$f5561d2634fb28a969f2dO8QeQ70f4bjCnF/.GvPpjj.8jgmtzZP2' == crypt("enter-new-password",'$2a$09$f5561d2634fb28a969f2dO8QeQ70f4bjCnF/.GvPpjj.8jgmtzZP2'); What I need is a crypt function in Golang that will also evaluate to true. ATTEMPT 1 I tried this but it evaluated to false: import "github.com/nyarla/go-crypt" log.Println("$2a$09$f5561d2634fb28a969f2dO8QeQ70f4bjCnF/.GvPpjj.8jgmtzZP2" == crypt.Crypt("enter-new-password","$2a$09$f5561d2634fb28a969f2dO8QeQ70f4bjCnF/.GvPpjj.8jgmtzZP2")) ATTEMPT 2 I also tried to define and use this crypt

Is there a way to reverse a crypt() in c?

阅读更多关于 Is there a way to reverse a crypt() in c?

问题 Not sure if this is possible but I want to be able to start with a string, and then figure out what the input must be into the crypt in order to get this string out. Or maybe it's impossible, which would be the whole purpose of the thing anyways? Yes, there is a salt in the code where I am trying this. 回答1: By design intent, crypt() is a one-way hash. As everyone has said, that means that the intent is that it would be computationally infeasible to discover a plaintext string that produces

Is the crypt() function declared in unistd.h or crypt.h?

阅读更多关于 Is the crypt() function declared in unistd.h or crypt.h?

问题 I'm using GCC 4.6.0 ( on an otherwise unidentified platform ). I am using the crypt() function to encrypt a password. I have never used that function before so I checked out the main page: man 3 crypt And it says to include the unistd.h header. However, when I did that, I got an implicit warning for the crypt function. warning: implicit declaration of function ‘crypt’ [-Wimplicit-function-declaration] I did a bit of searching and I found that you have to include the crypt.h . However, how

Where 2x prefix are used in BCrypt?

阅读更多关于 Where 2x prefix are used in BCrypt?

The question is the same title, Where $2x$ is used in BCrypt? The following scenario is right? We have a set of passwords that hashed with $2a$ prefix already, when the Server PHP version was earlier 5.3.7 . Now we upgraded the PHP to 5.3.7+ , now we must firstly verify previous passwords with $2x$ algorithm then rehash the password with $2y$ prefix. That's right? Note to wikipedia editors : Content in this answer is in the public domain; i know because i wrote it. I wrote it first for myself, and later put it on Stackoverflow. I also know it because everything on Stackoverflow is copyleft.

(PHP) How to use crypt() with CRYPT_BLOWFISH?

阅读更多关于 (PHP) How to use crypt() with CRYPT_BLOWFISH?

问题 First, I see that to use CRYPT_BLOWFISH, i need to use a 16 char salt starting with $2a$. However, the php.net documentation for crypt() says that some systems don't support CRYPT_BLOWFISH. How often is that the case? Next, from their example on the docs, I see I use crypt() as follows: <?php $password = crypt('mypassword'); // let the salt be automatically generated /* You should pass the entire results of crypt() as the salt for comparing a password, to avoid problems when different hashing

我正在做一个 CTF 样本，他们给了我的文件哈希，我通过JtR运行它，我得到了我的密码。事情是，哈希给了我，有没有办法找到该文件的散列，如果没有给出？有2分需要解决才能打破密码，HASH 和加密算法。我一直在使用密码保护的 zip 文件练习，所以我认为是使用 zip 2.0 或某种或某种 AES，我可以借助谷歌的帮助。不过,我不知道如何访问该 hashed 数据的 zip 文件的元数据。由于它是一个标准，因为压缩某些东西在存储密码时不需要使用算法。然而，需要一些排序的哈希。有谁知道如何使用这个密码保护的 zip 文件的例子，知道这是如何做的？我现在使用一个 macbook pro。(成才按：像是外文翻译过来的，很多句子不通顺。) 文件中没有提取密码哈希值，约翰开膛手（JtR）并没有这样做。您可以下载 JtR 的代码,以了解它是如何完成的。这里是一个关于如何获得所谓的“非哈希”信息的一个小文章。.zip 和 .rar 文件使用 zip2john 和 rar2john： http://www.cybercrimetech.com/2014/07/how-to-cracking-zip-and-rar-protected.html 为了纠正这个不当行为，JtR 实际上并没有从文件中“检索出哈希”。它从文件中提取某些信息。例如，如 rar2john 代码中所述： Output

to use CRYPT_BLOWFISH on php 5.2 that doesn't support it

阅读更多关于 to use CRYPT_BLOWFISH on php 5.2 that doesn't support it

I am running my page on PHP 5.2 that does not support CRYPT_BLOWFISH but CRYPT_MD5 , and have heard that the blowfish is much more safer than md5. Since I am not the supervisor thing, I can not upgrade PHP to a version that supports it. Is there any hack for using CRYPT_BLOWFISH on PHP 5.2? and, $hash_key = crypt($something, '$2a$anySalt'); is pasting '$2a$' at the very first side correct? quite confused. P.s. If I use crypt() with CRYPT_BLOWFISH , will bcrypt work well in the crypt() function? You can use PHPASS which has fallbacks to support systems that don't support CRYPT_BLOWFISH.

How to create and store password hashes with Blowfish in PHP

阅读更多关于 How to create and store password hashes with Blowfish in PHP

问题 1) How do you create secure Blowfish hashes of passwords with crypt()? $hash = crypt('somePassword', '$2a$07$nGYCCmhrzjrgdcxjH$'); 1a) What is the significance of "$2a"? Does it just indicate that the Blowfish algorithm should be used? 1b) What is the significance of "$07"? Does a higher value imply a more secure hash? 1c) What is the significance of "$nGYCCmhrzjrgdcxjH$"? Is this the salt that will be used? Should this be randomly generated? Hard-coded? 2) How do you store Blowfish hashes?
