How can I do AES 256 encryption in Blackberry... I am using for encryption : but not get data AES256 standard : private static byte[] encrypt( byte[] keyData, byte[] data ) throws CryptoException, IOException { // Create the AES key to use for encrypting the data. // This will create an AES key using as much of the keyData // as possible. AESKey key = new AESKey( keyData ); // Now, we want to encrypt the data. // First, create the encryptor engine that we use for the actual // encrypting of the data. AESEncryptorEngine engine = new AESEncryptorEngine( key ); // Since we cannot guarantee that

I am asking this question to confirm whether the RijndaelManaged class in C# is equivalent to AES encryption. From what I have been reading, RijndaelManaged was the algorithm of choice to implement AES encyrption. Can someone confirm this please? Is RijndaelManaged algorithm safe to be used for a web project? Thanks :) The AES algorithm was selected in a competition held by NIST between 1997 and 2000. The winner was an algorithm called Rijndael. NIST specified that the AES algorithm was to have a 128-bit block size. As Rijndael supports block sizes of 128, 160, 192, 224, and 256 bits, the

i m writing one application which encrypt and decrypt data using AES (ECB) mode. Encrypted data of blackberry code successfully decrypt by php code. but problem is that when i get encrypted text from php i m not able to decrypt it with blackberry code..even i m not getting any exception. here is my code to encrypt and decrypt text. public static byte[] encrypt( byte[] keyData, byte[] data ) throws CryptoException, IOException { // Create the AES key to use for encrypting the data. // This will create an AES key using as much of the keyData // as possible. AESKey key = new AESKey( keyData ); //

微信 AES 解密报错 Illegal key size Java 环境 java version "1.8.0_151" Java(TM) SE Runtime Environment (build 1.8.0_151-b12) Java HotSpot(TM) 64-Bit Server VM (build 25.151-b12, mixed mode) 问题 问题日志 最近在迁移的服务器，在迁移完之后， 一个有关微信小程序的日志打印下面的报错信息。 c.t.b.a.c.weixin.aes.WXBizMsgCrypt - 小程序解密异常 java.security.InvalidKeyException: Illegal key size 解密失败，看了下解密的密钥是正确的，没有任何问题。 这个在 经典 下是可以运行的，在 VPC 下运行不了。 (因为最近在进行阿里云网络迁移) 问题原因 微信在进行数据传输的时候，会进行加密，微信使用的 AES 加密使用的是 256位，Java 默认使用的解密包是 local_policy.jar 和 US_export_policy.jar ，但是这个默认的只支持 128位的解密(java 版本在 1.8.0_161之后就没有这个问题了，默认是支持)。我们的版本是 1.8.0_151 正好默认是只支持 128位的解密(其实不是不支持

I'm creating a system in which users can store messages via PHP with a MySQL database, and I am using the MySQL AES_ENCRYPT function to encrypt the contents of these messages. Here is my posts table: CREATE TABLE IF NOT EXISTS `posts` ( `id` int(11) NOT NULL AUTO_INCREMENT, `user` int(11) DEFAULT NULL, `group` int(11) DEFAULT NULL, `body` varbinary(1000) NOT NULL, `ip` varchar(45) NOT NULL, `date` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP, `replyto` int(11) DEFAULT NULL, PRIMARY KEY (`id`), KEY `replyto` (`replyto`), KEY `user` (`user`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT

I am trying to encrypt/decrypt a string in an AES-128 GCM format in objective c. I have looked everywhere but can't seem to find a working solution. Enrique Not so long ago I had a similar problem and the best answer I could find was this one . To sum up, iOS has some functions to do what you want but they are private. So, until Apple decides to release these functions, I opted for developing my own library, currently stored in GitHub and available in CocoaPods . The case you describe could be implemented this way: #import <CommonCrypto/CommonCrypto.h> #import "IAGAesGcm.h" // For the case you

There were many questions about AES, but I have the following problem. I'm currently using the following AES implementation to encrypt data byte [] PRFkey = {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15}; byte [] plaintext = {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15}; SecretKeySpec encryptionKey=new SecretKeySpec(PRFkey, "AES"); Cipher cipher=Cipher.getInstance("AES"); cipher.init(Cipher.ENCRYPT_MODE, encryptionKey); byte[] encryptedData=cipher.doFinal(plaintext); And it turned out that result is 32-bytes (256 bits). So I'm using AES-256. This implementation is to slow for me. How can I switch to AES

I'm reverse engineering an API and I found out that it uses AES-256-CBC for encryption. I also found out that it uses EVP_BytesToKey to encrypt HTTP requests. After I found out about this I tested it but I had some issues (probably because I'm inexperienced). I don't know where to put the password And this is what needs to be decrypted: FP2xttTh/wm5Kr45Vh/PEvsdxgfL3NgxxMMk9hTkPfJd7vSJXTlhjiZlQajnBcMAVknANpv5FNCMRD+epDSOA2epKOzstSmhC0il2TlwgKqaT+97zomCMUCIfdaJYnLz5gBth1MIpxO30bx9zPg8cbOJcLnMmCo3vtSDCalgjHICf5FevI7DgrWnWC1U4wab0rx/rWhGFJ0sOW1ImDi9DkCy+guQZIrojbZxRlvGzv1mU
