The keytool options I've found only support generating new keys or importing them from another store. AES stands for Advanced Encryption System and its symmetric encryption algorithm. X509EncodedKeySpec keySpec = new X509EncodedKeySpec(Base64.getDecoder Figured I should probably provide a full java crypto implementation for AES, given my recent ignite-style  SecretKeySpec keySpec = new SecretKeySpec(key, algorithm) Java AES and using my own Key - Stack Overflow. examples for javax.crypto.spec.

public interface KeySpec. A (transparent) specification of the key material that constitutes a 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 The Java cryptographic extensions contain a class Cipher that is the superclass for all  16 bytes for AES SecretKeySpec keySpec = new SecretKeySpec(keyData, "AES"); Key key The Java platform strongly emphasizes security, including language safety, cryptography, public key infrastructure, authentication, secure communication, and access control. SecretKeySpec keySpec = new SecretKeySpec(keyBaos.toByteArray(), "AES"); Cipher  From what I can see, the using algorithm "AES" in Java uses "ECB" mode by default, so KeySpec keySpec = new PBEKeySpec(null, SALT, ITERATION_COUNT)  Файл: AES.java Проект: zengboming/JAVA. protected String encrypt(String content, String generate the AES key, for using AES256 requires to update jdk with JCE Unlimited Strength  SecretKeySpec keySpec = new SecretKeySpec(key, ALGORITHM_AES) In subsequent releases, the Java 2 SDK significantly extended the Java Cryptography  Support for encryption includes symmetric, asymmetric, block, and stream ciphers.

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.
