Release date:Updated on: Affected Systems:Sourceforge libcryptDescription:--------------------------------------------------------------------------------Bugtraq id: 53729Cve id: CVE-2012-2143 Libcrypt is an ansi c encrypted library. Libcrypt has the password encryption vulnerability in implementation. When processing characters that cannot be represented by 7-bit ASCII, The DES implementation used in the crypt () function has a programming error, att

The irreversible cryptographic functions are: MD5 (), Crypt () MD5 () is used to calculate MD5. The syntax is: string MD5 (string str); Crypt () encrypts the string with the UNIX standard cryptographic DES module. This is a one-way cryptographic function that cannot be decrypted. To compare strings, place the first two characters of the encrypted string in the salt parameter, and then the encrypted string.

How to compare passwords during logon To improve security, Linux introduces salt, a so-called salt, which is a random number and a 12-bit value, When a user sets a password, a random salt is generated and encrypted with the user's password to obtain an encrypted string (salt is included in the string in plaintext ), Store i

The crypt () function returns a string that is encrypted using the DES, Blowfish, or MD5 algorithms. On different operating systems, the function behaves differently, and some operating systems support more than one type of algorithm. At installation time, PHP checks what algorithms are available and what algorithms are used. The specific algorithm relies on the format and length of the salt parameter. Salt makes encryption more secure by increasing

Release date:Updated on: Affected Systems:PHP 5.3.xDescription:--------------------------------------------------------------------------------PHP is a popular scripting environment. PHP has a security vulnerability in the implementation of the "crypt ()" function. Remote attackers can exploit this vulnerability to bypass certain security restrictions. This vulnerability occurs when the "crypt ()" functi

This article mainly for you in detail the PHP use Crypt () function to encrypt, with a certain reference value, interested in small partners can refer to One, the code Ii. Results of operation Parameters do not have a salt, each encryption results in a different cipher.The $STR value before encryption is: Apply the crypt () function for one-way encryption!The value of $str after encryption is: $1$re4.gg

For everyone to introduce in detail PHP using crypt () function for encryption, has a certain reference value, interested in small partners can refer to One, the code Ii. Results of operation Parameters do not have a salt, each encryption results in a different cipher.The $STR value before encryption is: Apply the crypt () function for one-way encryption!The value of $str after encryption is: $1$re4.gg4.

My answer, but the complexity is not very satisfied, is an exponential level of complexity. But the test data is weak, or AC. Found on the Internet, are brute force solution, do not know whether there is a better solution.Two errors were made in the solution, the first, map#include Programming-challenges Crypt Kicker (110204)
