aes 128、192、256位，cbc、cfb、ecb、ofb、pcbc在线加密解密
AES加解密总共有以下这些
算法/模式/填充 字节加密后数据长度 不满16字节加密后长度
AES/CBC/NoPadding 16 不支持
AES/CBC/PKCS5Padding 32 16
AES/CBC/ISO10126Padding 32 16
AES/CFB/NoPadding 16 原始数据长度
AES/CFB/PKCS5Padding 32 16
AES/CFB/ISO10126Padding 32 16
AES/ECB/NoPadding 16 不支持
AES/ECB/PKCS5Padding 32 16
AES/ECB/ISO10126Padding 32 16
AES/OFB/NoPadding 16 原始数据长度
AES/OFB/PKCS5Padding 32 16
AES/OFB/ISO10126Padding 32 16
AES/PCBC/NoPadding 16 不支持
AES/PCBC/PKCS5Padding 32 16
AES/PCBC/ISO10126Padding 32 16
一、不带模式和填充来获取AES算法的时候，其默认使用AES/ECB/PKCS5Padding（输入可以不是16字节，也不需要填充向量）
Cipher cipher = Cipher.getInstance("AES");
下面是 AES/ECB/PKCS5Padding 128位、192位、256加解密 完整代码
String content = "在线助手";
// 生成密钥需要的密码值
String key = "www.it399.com";
/**
* AES加密方式一:AES不指定模式和填充，默认为 ECB/PKCS5Padding
*
* 不能使用填充向量
* java.security.InvalidAlgorithmParameterException: ECB mode cannot use IV
*/
System.out.println("【0】AES不指定模式和填充，默认为 ECB/PKCS5Padding，输入可以不是16字节，也不需要填充向量\n");
//128
byte[] encrypt = encryptOrdecrypt(true,content.getBytes(CHARSET),key,null,AESType.AES_128,EncodeType.AES_DEFAULT);
encryptOrdecrypt(false,encrypt,key,null,AESType.AES_128,EncodeType.AES_DEFAULT);
//192
encrypt = encryptOrdecrypt(true,content.getBytes(CHARSET),key,null,AESType.AES_192,EncodeType.AES_DEFAULT);
encryptOrdecrypt(false,encrypt,key,null,AESType.AES_192,EncodeType.AES_DEFAULT);
//256
encrypt = encryptOrdecrypt(true,content.getBytes(CHARSET),key,null,AESType.AES_256,EncodeType.AES_DEFAULT);
encryptOrdecrypt(false,encrypt,key,null,AESType.AES_256,EncodeType.AES_DEFAULT);
结果如下:
【0】AES不指定模式和填充，默认为 ECB/PKCS5Padding，输入可以不是16字节，也不需要填充向量

初始化加密模式的时改成
Cipher cipher = Cipher.getInstance(“AES/CBC/NoPadding”);
java.security.InvalidKeyException: Parameters missing解决办法:
if (modeAndPadding.equals(EncodeType.AES_CBC_NoPadding)) {
//指定一个初始化向量 (Initialization vector，IV)， IV 必须是16位
cipher.init(Cipher.ENCRYPT_MODE, keySpec, new IvParameterSpec(getIV()));
} else {
cipher.init(Cipher.ENCRYPT_MODE, keySpec);
}
