Its not that simple, though it should be. OpenSSL used to provide a function to get the capabilities detected for an ia32 processor, but its no longer available. See the discussion of OPENSSL_ia32cap_loc in the OPENSSL_ia32cap man page . Also see Verify AES-NI use at runtime? on the OpenSSL mailing list. If you are linking to the OpenSSL static library, then you can use: extern unsigned int

I have observed the following when I worked with Cipher . Encryption code: Cipher aes = Cipher.getInstance("AES"); aes.init(Cipher.ENCRYPT_MODE, generateKey()); byte[] ciphertext = aes.doFinal(rawPassword.getBytes()); Decryption code : Cipher aes = Cipher.getInstance("AES"); aes.init(Cipher.DECRYPT_MODE, generateKey()); byte[] ciphertext = aes.doFinal(rawPassword.getBytes()); I get IllegalBlockSizeException ( Input length must be multiple of 16 when ...) on running the Decrypt code. But If I change the decrypt code to Cipher aes = Cipher.getInstance("AES/ECB/PKCS5Padding"); //I am passing the

I've got an Android application and I'm storing username and passwords on the device, and I need to encrypt them AES 256. From looking at examples, this is what I have so far: public class Security { Cipher ecipher; Cipher dcipher; // 8-byte Salt byte[] salt = { (byte)0xA9, (byte)0x9B, (byte)0xC8, (byte)0x32, (byte)0x56, (byte)0x35, (byte)0xE3, (byte)0x03 }; // Iteration count int iterationCount = 19; public Security

I also have a splineHull dataset, which also contains numeric columns "pauseMedian" and "numTotalPauses", plus a 6-level factor "microstyle" I have the following code, which works perfectly. It plots a scatter plop and then overlay it with splineHull polygons colored according to "microstyle". script 1: ggplot(data=merged,aes(x = pauseMedian, y = numTotalPauses)) + geom_point() + geom_polygon(data = splineHull, mapping=aes(x

How can I use the private to decrypt the data? 回答1: In .Net, you can create your key pair like this: public static Tuple<string, string> CreateKeyPair() { CspParameters cspParams = new CspParameters { ProviderType = 1 }; RSACryptoServiceProvider rsaProvider = new RSACryptoServiceProvider(1024, cspParams); string publicKey = Convert.ToBase64String(rsaProvider.ExportCspBlob(false)); string

Which is the better solution, AES or Blowfish with the same key length? We can assume that the attacker has great resources (softwares, knowledge, money) for cracking the file. 回答1: Probably AES. Blowfish was the direct predecessor to Twofish. Twofish was Bruce Schneier's entry into the competition that produced AES. It was judged as inferior to an entry named Rijndael, which was what became AES. Interesting aside: at one point

经过多次尝试，模拟登录淘宝终于成功了，实在是不容易，淘宝的登录加密和验证太复杂了，煞费苦心，在此写出来和大家一起分享，希望大家支持。 温馨提示 现在淘宝换成了滑块验证了，比较难解决这个问题，以下的代码没法用了，仅作学习参考研究之用吧。 本篇内容 1. python模拟登录淘宝网页 2. 获取登录用户的所有订单详情 3. 学会应对出现验证码的情况 4. 体会一下复杂的模拟登录机制 探索部分成果 1. 淘宝的密码用了AES加密算法，最终将密码转化为256位，在POST时，传输的是256位长度的密码。 2. 淘宝在登录时必须要输入验证码，在经过几次尝试失败后最终获取了验证码图片让用户手动输入来验证。 3. 淘宝另外有复杂且每天在变的 ua 加密算法，在程序中我们需要提前获取某一 ua 码才可进行模拟登录。 4. 在获取最后的登录 st 码时，历经了多次请求和正则表达式提取，且 st 码只可使用一次。 整体思路梳理 1. 手动到浏览器获取 ua 码以及 加密后的密码，只获取一次即可，一劳永逸。 2. 向登录界面发送登录请求，POST 一系列参数，包括 ua 码以及密码等等，获得响应，提取验证码图像。 3. 用户输入手动验证码，重新加入验证码数据再次用 POST 方式发出请求，获得响应，提取 J_Htoken。 4. 利用 J_Htoken 向 alipay 发出请求，获得响应，提取 st
