As we all know, unity gave up flash in 2013, but sometimes it really needs to flash, such as the web-side needs Unity Web Player plugin, many browsers are blocked, Flash will not, because he is Microsoft.U3D when packaging Flash API is not modifiable, the default is the Flash API, packaged out is as (ActionScript code) compiled. So many net2.0 API can not be used, such as System.Security.Cryptography This library, note: This library is C # integrated good encryption and decryptionU3D export Flas

These days to find a serious can use things that is really difficult, on-line search a big pile, serious can use few, get, finally still have to rely on their own, happened to meet the need to AES plus decryption place, but also Java and C # Mutual decryption operation, here to do a memoHere the use of encryption and decryption using the Base64 transcoding method, the ECB mode, pkcs5padding fill, password must be 16 bits, otherwise it will be error ha

When studying Discuz, we found that Discuz has a fairly perfect encryption algorithm (relative). This algorithm can encrypt the data, save it, and then restore it using the secret key that was previously encrypted when needed. In addition to this, there is the AES algorithm can be very good data encryption, in the transmission process is not easy to be cracked. In PHP, we must first install the MCrypt this module, and add the appropriate version of

This article describes how to solve the inconsistency between AES encryption and other languages in Node. js. For example, if you need to communicate with C # and JAVA, refer Example 1: These days have been plagued by a problem. The AES encryption of Nodejs is inconsistent with that encrypted by Java and C. Of course, you cannot decrypt it. Tangle for a long time: Later, it was not enough. I read the sourc

[AES] A symmetric encryption algorithm, used by DES. For more information about encryption, see Java encryption and decryption symmetric encryption algorithm asymmetric encryption algorithm MD5 BASE64 AES RSA [Code] There are many codes. Some of them are not the content code of this Article. Let's take a look at them for details. Package com. uikoo9.util. encrypt; import java. math. bigInteger; import jav

In the above "16.app back-end how to ensure communication security--url signature" mentioned, URL signature has two shortcomings, these two shortcomings, if the use of symmetric encryption method, you can completely avoid these two shortcomings. In this article, we will introduce the specific principles of symmetric encryption, and detailed solutions to make app communication more secure.1. Principle of symmetric encryptionUsing the encryption method of single-key cryptosystem, the same key can

Work encountered Nodejs through AES encryption, Android client Java decryption, the same nodejs also need to decrypt Android client encrypted content, found that two encryption results are not the same, query data found that the Java end needs to MD5 encryption, the following is the AES ECB encrypted content, If it is CBC, it also needs to encrypt the secret key MD5: Nodejs: /** *

Why do I have to implement the go aes-cbc-256 encryption and decryption function? The previous project was implemented using PHP. Now we are going to use go for reconstruction. This function is required. This common feature allows us to search for a ready-made example on the Internet, so you can implement a pair of encryption and decryption functions in minutes based on the existing go API. If you think right, it will fail when you run it. Well, there

When the server communicates with the terminal device over HTTP, it is often captured by the network, decompilation (AndroidAPK decompilation tool), and other technologies to obtain the HTTP communication interface address and parameters. To ensure information security, we use AES + RSA to encrypt and decrypt interface parameters. 1. about the RSA encryption mechanism: the public key is used to encrypt the data, and the private key is used to decrypt

The mobile is getting more and more fire, we in the development process, always encounter with the mobile side to deal with the scene. In order to make the data interaction more secure, we need to encrypt the data transmission. Today, we studied the encryption of several languages, and realized it. Net,java (andriod), iOS are the same set of cryptographic algorithms, the following share to everyone.AES encryption has a variety of algorithm modes, the following provides two sets of mode available

Today in the Android project using AES to decrypt the data, encountered a lot of problems, the Internet also found a lot of information, also not. But finally let me get out, here to record this, do not let others go my detour, because most of the online example is not feasible. Okay, let's start with the explanation. 1, AES Tool class Package com.example.cheng.aesencrypt; Import Android.text.TextUti

Base64 encoding, this approach is very elementary and simple. the specific understanding of the individual coding scenarios can be referenced in this blog, 50993861. MD5 Digest Algorithm , which is a hash function, extracts the characteristics of the data, the output is an irreversible hash value, used to represent a certain information a without exposing the content of information A, generally used in the digital signature scene. The encryption method is determined: Finally, the sens

Recently I used to encrypt text content, so I checked the common encryption algorithms: Des (Data Encryption Standard): symmetric algorithm, Data Encryption Standard, fast, suitable for encrypting a large amount of data;3DES (Triple DES): It is a symmetric algorithm based on Des. it encrypts a piece of data three times with three different keys, with higher strength;RC2 and RC4: symmetric algorithms that use variable-length keys to encrypt a large amount of data, faster than DES;Idea (Internatio
