After several years of entering the programmer industry, there have been gains (enhanced technology) and efforts (time and sub-health status) in the past few years ). Of course, there is no regret, and the code is still long !!!
On The Way, never stop !!!
In the development process, I have also accumulated some exp
The difference between 16-bit MD5 encryption and 32-bit MD5 encryptionMD5 encryption is usually a 32-bit encoding, and in many places will use 16-bit encodingWhat difference do they have?16-bit encryption is to extract the middle 16 bits from the 32-bit MD5 hash!Actually cracked 16-bit MD5 hash is slower than cracking 32-bit MD5 hashBecause he has one more step,
Several common encryption functions in PHP and common encryption functions in PHP
MD5 encryption:
String md5 (string $ str [, bool $ raw_output = false])
1. by default, md5 () returns a hash value in the hexadecimal format of 32 characters. It accepts two parameters: the first is the string to be encrypted, and the second is the Boolean value of raw_output, the d

Advanced Encryption Standard (English: Advanced encryption Standard, abbreviation: AES), also known as the Rijndael encryption method in cryptography, is a block encryption standard used by the U.S. federal government. This standard, which replaces the original DES, has been analyzed and widely used worldwide. After fi

13.1 DH
The cornerstone of asymmetric algorithms
It can only be used for key distribution and cannot be used for data encryption and decryption. Generally, AES is used to encrypt data.

Unity3d Project Encryption prevents anti-compilation using the Virbox LM encryption scheme. For the Code and resource protection in Unity3d game project, Virbox LM has a perfect solution that can effectively prevent the code from being recompiled and the resource files being stolen. The Assembly-scharp.dll can be encrypted directly, and the mono file is automatically encrypted. The. Assets resource file can
Difference:MD5 Encryption:Encrypt from the original string into another stringDecryption requires the original encrypted string to be re-encrypted two times encryption results are consistentT=RSA Encryption:Generate a key pair (public key + private key) from the original string when encryptingDecryption by the public and private keys to decrypt the original string to decrypt the consistency of the comparisonPersonal Opinion: RSA
Asymmetric encryption has been rated as the encryption standard, mainly includes (public key encryption private key decryption, or private key encryption public key decryption) This article mainly explains how to generate the public and private keys and string encryption and
In general, most packet encryption algorithms encrypt and decrypt data in 64-bit groupings. But almost all cryptographic work involves far more than 64 bits of data, so it is necessary to repeat the encryption process until all the groupings have been processed. The repetitive approach involved in this packet encryption is called packet
For most password encryption, we can use MD5, SHA1 and other methods. Can effectively prevent data disclosure, but these methods apply only to data encryption that does not need to be restored. For information that needs to be restored, a reversible encryption decryption algorithm is required, and the following set of PHP functions is the method that implements t
