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 秘钥长度，128，加密方式： AES,加密结果:09942AC3BB18703E2BAF29EC18E69BCC 秘钥长度，128，解密方式： AES,解密结果:在线助手 秘钥长度，192，加密方式： AES,加密结果:B9F574EF92836DFD2CC0EE03E7A0E717 秘钥长度，192，解密方式： AES,解密结果:在线助手 秘钥长度，256，加密方式： AES,加密结果:118CD83850A220EFD791FF6B1FF180F8 秘钥长度，256，解密方式： AES,解密结果:在线助手 二、AES/CBC 加密方式 2.1 AES/CBC/NoPadding 输入必须是16字节，不然报错 javax.crypto.IllegalBlockSizeException: Input length not multiple of 16 bytes CBC模式必须提供初始向量IvParameterSpec，不然报错 java.security.InvalidKeyException: Parameters missing content： 在线助手 key： www.it399.com111 javax.crypto.IllegalBlockSizeException: Input length not multiple of 16 bytes at com.sun.crypto.provider.CipherCore.finalNoPadding(CipherCore.java:1041) at com.sun.crypto.provider.CipherCore.doFinal(CipherCore.java:1009) at com.sun.crypto.provider.CipherCore.doFinal(CipherCore.java:847) at com.sun.crypto.provider.AESCipher.engineDoFinal(AESCipher.java:446) at javax.crypto.Cipher.doFinal(Cipher.java:2165) at com.csy.spring.it399.controller.encode.aes.AESUtil.encrypt(AESUtil.java:80) at com.csy.spring.it399.controller.encode.aes.AESUtil.main(AESUtil.java:200) java.security.InvalidKeyException: Parameters missing at com.sun.crypto.provider.CipherCore.init(CipherCore.java:470) at com.sun.crypto.provider.AESCipher.engineInit(AESCipher.java:313) at javax.crypto.Cipher.implInit(Cipher.java:802) at javax.crypto.Cipher.chooseProvider(Cipher.java:864) at javax.crypto.Cipher.init(Cipher.java:1249) at javax.crypto.Cipher.init(Cipher.java:1186) at com.csy.spring.it399.controller.encode.aes.AESUtil.decrypt(AESUtil.java:117) at com.csy.spring.it399.controller.encode.aes.AESUtil.main(AESUtil.java:202) encode： null decode： null

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); }
