Aes keyspec java
It is a symmetric algorithm, that is same key is used for encryption and decryption. Here is the code to implement AES in Java:… Java Source Code Listing 1 shows the Java source code. The name of the class is AesBase64Wrapper since the responsibility of the class is to provide a convenient wrapper around AES encryption and Base64 encoding. Base64 encoding is used since encryption produces bytes which don't translate into visible screen characters. Jawad-Dev: he implementado un modo CBC AES enc. He implementado un mecanismo de cifrado y descifrado AES en modo CBC en el que estoy generando Random IV y Random Secret key para cada intento de cifrado que se recomienda.

I use library CryptoJS for AES encryption. var CryptoJS = require ("crypto-js"); class TravisAes { constructor () { this._keySize = 256; this._ivSize = 128; this._iterationCount = 1989; } generateKey (salt, passPhrase) { return CryptoJS.PBKDF2 (passPhrase, CryptoJS.enc.Hex.parse (salt), { keySize: this._keySize / 32, iterations: this._iterationCount }); } encryptWithIvSalt (salt, iv, passPhrase, plainText) { let key = this.generateKey (salt, passPhrase); let To encrypt the file contents, we create a Cipher object from the AES key. Cipher ci = Cipher.getInstance("AES/CBC/PKCS5Padding"); ci.init(Cipher.ENCRYPT_MODE, skey, ivspec); Finally, the file contents are encrypted and written into the output. try (FileInputStream in = new FileInputStream(inputFile)) { processFile(ci, in, out); } AES is a strong algorithm to encrypt or decrypt the data. Java, .NET and C++ provide different implementation to achieve this kind of encryption. Java has provided certain API's by which data can be encrypted using AES algorithm.
