　　.net进行微信公众号开发的例子好像比较少，这里做个笔记 　　首先，我们需要让微信能访问到我们的项目，所以要么需要有一个可以部署项目的连接到公网下的服务器，要么可以通过端口转发将请求转发到我们的项目，总之，就是要让微信服务器能访问到我们的项目。 　　另外，需要注意一下，微信回调通知的地址目前只支持80端口和443端口，所以一般的，我们都需要做个虚拟路径 　　其他的就不多说了，具体配置可以在微信公众号的开发文档中接入： https://developers.weixin.qq.com/doc/offiaccount/Basic_Information/Access_Overview.html 　　接入过程中会遇到很多坑，什么Url超时，Token验证错误等等，反正就是一些触不及防，当我们接入开发完后，发现我们使用的是明文传送，那当然就不行了，改成密文又要使用AES加密，反正接入不知道遇到多少坑 　　下面贴出我接入的代码，复制一下，稍稍修改就可以用了，可直接验证接入，支持明文密文传输： 　　一个加密解密辅助类：　　 using System; using System.Collections; using System.Collections.Generic; using System.IO; using System.Linq; using System.Net; using

I've seen How many usage does "volatile" keyword have in C++ function, from grammar perspective? about use of the volatile keyword on functions, but there was no clear explanation of what Case 1 from that question did. Only a statement by one of the respondents that it seemed pointless/useless. Yet I cannot quite accept that statement, since the AES software implementations for GNUC have been used for literally years, and they have a number of functions like this: INLINE volatile void functionname( /* ... */ ) { /* ... */ asm( /* ... */ ) // embedded assembly statements /* ... */ } There has

Closed . This question needs details or clarity. It is not currently accepting answers. Learn more . Want to improve this question? Add details and clarify the problem by editing this post . I am trying to encrypt a data in java and decrypt the same in javascript. There is already a similar question in SO but it does not work for me. My question is - Encrypted Text given by Java code is not getting decrypted by Javascript. I have hardcoded the the encrypted text and key in my JS below. P.S. I know decryption on the UI is of no use as Key will be visible and any user can decode the code. But my

In AES, my understanding is that salt is the stuff to make the passphrase more secure and it wont be added into encrypted text. But IV is the stuff used to encrypt the first block of message and will be added into the encrypted text. Do I get anything wrong? AES itself does not directly use a salt (or indeed, an IV). A situation when you might use a salt in combination with AES is when you are using Password Based Encryption (PBE). In this scheme, a human-memorizable password is used, in combination with a salt, to generate an AES key. A salt is used so that the same password does not always

This is my java code. Now I want to implement same functionality in Objective-C. Cipher encryptCipher; IvParameterSpec iv = new IvParameterSpec(key); SecretKeySpec skeySpec = new SecretKeySpec(key, "AES"); encryptCipher = Cipher.getInstance("AES/CBC/PKCS5Padding"); encryptCipher.init(Cipher.ENCRYPT_MODE, skeySpec, iv); byte[] encrypted = encryptCipher.doFinal(dataToEncrypt.getBytes()); Log.d("TAG", "encrypted string:" + Base64.encodeToString(encrypted, Base64.DEFAULT)); return Base64.encodeToString(encrypted, Base64.DEFAULT).trim(); This is my iOS implementation - (NSData *

I have to build a simple authorization server for a project. The server has to distribute AES keys to allow its clients to communicate with each other. When encrypting the AES key using RSA, I run into this error: "javax.crypto.IllegalBlockSizeException: Data must not be longer than 117 bytes". Which is weird, since the lenght of my AES key is 128 bits = 16 bytes. Here is the code generating the error: private void createAndSendAES() throws NoSuchAlgorithmException, NoSuchPaddingException, IllegalBlockSizeException, IOException, InvalidKeyException, BadPaddingException { KeyGenerator keyGen =
