The classic PHP encryption and decryption function Authcode () fixes the version code and encrypts and decrypts the authcode. The classic PHP encryption and decryption function Authcode () fixes the version code. encryption and decryption are used by many people. This function is used by the Discuz program to encrypt and decrypt strings, you can use the classic P
PHP Custom encryption and Decryption program instance, PHP encryption and decryption instance
This article describes the PHP custom encryption and decryption program. Share to everyone for your reference. The specific analysis is as follows:
PHP3 Cryption is a very easily cracked, insecure cryptographic feature that should not be very important to use, although
thinkphp Development: Safe Mode message encryption and decryption, thinkphp decryption
The use of Thinkphp official WeChat package, the use of different modes can be successful, but the safe mode is not, now will analyze the results of the record.

In fact, someone on the internet has already analyzed this, and written a tool, but I tested a lot of, no one can use, so I decided to analyze from the beginning.
Open the shield after the encryption of the source code, you can see that
It is written with an ad annotation and cannot be deleted because there is a MD5 parity code at the end of the file to verify that the code has been modified, as shown in
Again look at the code section, found inside are garbled, in fact, this is a camoufla
This article describes the encryption and decryption function in PHP and DES encryption and decryption application, share for everyone to reference. Specifically as follows:
Examples, examples of PHP encryption decryption
Cryptographic functions:
Copy Code code as follows:
/*
* Function: Encrypt string to handle
* Parameter one: Content that
First download the PHP God Shield decryption tool decryptionThen unzip it into a folder and put the file you want to decrypt.Then create a new decode.php code to write:
Copy Code code as follows:
Require (' decryption.php ');
Decryption (' code.php ');
?>
After the execution will generate code_source.php source files.
Effect
At present, no problem found, if there are any questions
PHP uses OpenSSL for RSA encryption, if the plaintext to be encrypted is too long error, workaround: Encrypt the time 117 characters to encrypt once, and then all the cipher stitching into a cipher text, the decryption time needs 128 characters to decrypt, and then splicing into data.Encryption:/** * Encryption * @param $originalData * @return string|void * //*function Encrypt ($originalData) { if (Openssl_private_encrypt ($o
Recently, Tianyi decryption security team found that gandcrab4.0 was more active and has tracked many gandcrab4.0 variant ransomware events. A security warning has been issued to remind users to prevent gandcrab4.0 ransomware.
Currently, Tianyi decryption can successfully decrypt the gandcrab4.0 variant using the RSA + AES encryption algorithm Krab poisoning file within one hour.Phone 15169121444 QQ 315733
The RSA algorithm is the first algorithm that can be used for both data encryption and digital signature. It is easy to understand and operate, and is also popular. Its security is based on the difficulty of big integer factorization, while the big integer factorization is a famous mathematical problem. So far, there is no effective solution, therefore, the security of the RSA algorithm can be ensured.
The RSA algorithm consists of the generation of public and private keys, asymmetric encryptio
I analyzed the knowledge points used in the decryption process of Alibaba Cloud security two days ago. I sorted out the tools last night and encrypted them by the way. This is what we said yesterday. let's take a look at the call method. Download the decryption tool of php shield.

Preface
The message body signature and encryption functions have been launched, and there is indeed a security risk in plaintext transmission. In view of the wide range of users, it will certainly become the target of the public. Therefore, it is better to connect to the security mode as s
