AES 前后端 加密解密
1、服务端java加解密:
import org.apache.commons.codec.binary.Base64; import org.apache.commons.lang3.StringUtils; import sun.misc.BASE64Decoder; import javax.crypto.Cipher; import javax.crypto.KeyGenerator; import javax.crypto.spec.SecretKeySpec; public class AESUtil { //密钥 private static final String KEY = "1234567891234567"; //算法 private static final String ALGORITHMSTR = "AES/ECB/PKCS5Padding"; private AESUtil(){ } /** * base 64 encode * @param bytes 待编码的byte[] * @return 编码后的base 64 code */ public static String base64Encode(byte[] bytes){ return Base64.encodeBase64String(bytes); } /** * base 64 decode * @param base64Code 待解码的base 64 code * @return 解码后的byte[] * @throws Exception */ public static byte[] base64Decode(String base64Code) throws Exception{ return StringUtils.isEmpty(base64Code) ? null : new BASE64Decoder().decodeBuffer(base64Code); } /** * AES加密 * @param content 待加密的内容 * @param encryptKey 加密密钥 * @return 加密后的byte[] * @throws Exception */ public static byte[] aesEncryptToBytes(String content, String encryptKey) throws Exception { Cipher cipher = Cipher.getInstance(ALGORITHMSTR); cipher.init(Cipher.ENCRYPT_MODE, new SecretKeySpec(encryptKey.getBytes(), "AES")); return cipher.doFinal(content.getBytes("utf-8")); } /** * AES解密 * @param encryptBytes 待解密的byte[] * @param decryptKey 解密密钥 * @return 解密后的String * @throws Exception */ public static String aesDecryptByBytes(byte[] encryptBytes, String decryptKey) throws Exception { Cipher cipher = Cipher.getInstance(ALGORITHMSTR); cipher.init(Cipher.DECRYPT_MODE, new SecretKeySpec(decryptKey.getBytes(), "AES")); byte[] decryptBytes = cipher.doFinal(encryptBytes); return new String(decryptBytes); } /** * AES加密为base 64 code * @param content 待加密的内容 * @param encryptKey 加密密钥 * @return 加密后的base 64 code * @throws Exception */ public static String aesEncrypt(String content, String encryptKey) throws Exception { return base64Encode(aesEncryptToBytes(content, encryptKey)); } /** * 将base 64 code AES解密 * @param encryptStr 待解密的base 64 code * @param decryptKey 解密密钥 * @return 解密后的string * @throws Exception */ public static String aesDecrypt(String encryptStr, String decryptKey) throws Exception { return StringUtils.isEmpty(encryptStr) ? null : aesDecryptByBytes(base64Decode(encryptStr), decryptKey); } /** * 测试 */ public static void main(String[] args) throws Exception { String content = "123456"; System.out.println("加密前:" + content); System.out.println("加密密钥和解密密钥:" + KEY); String encrypt = aesEncrypt(content, KEY); System.out.println("加密后:" + encrypt); String decrypt = aesDecrypt(encrypt, KEY); System.out.println("解密后:" + decrypt); } }
加密前:123456
加密密钥和解密密钥:1234567891234567
加密后:ScD1XSdbJKBXv9cRHbKoUg==
解密后:123456
2、前端javascript加解密:
<html> <head> <script type="text/javascript" src="aes.js"></script> </head> <body> <script type="text/javascript"> var aesFun = { options:{ originalStr:"123456", aesKey:"1234567891234567" }, encrypt:function(word){ var key = CryptoJS.enc.Utf8.parse(this.options.aesKey); var srcs = CryptoJS.enc.Utf8.parse(word); var encrypted = CryptoJS.AES.encrypt(srcs, key, {mode:CryptoJS.mode.ECB,padding: CryptoJS.pad.Pkcs7}); return encrypted.toString(); }, decrypt:function(word){ var key = CryptoJS.enc.Utf8.parse(this.options.aesKey); var decrypt = CryptoJS.AES.decrypt(word, key, {mode:CryptoJS.mode.ECB,padding: CryptoJS.pad.Pkcs7}); return CryptoJS.enc.Utf8.stringify(decrypt).toString(); } } var options = aesFun.options; var encryptstr = aesFun.encrypt(options.originalStr); console.info("加密前:"+options.originalStr) console.info("加密秘钥和解密秘钥:"+options.aesKey) console.info("加密后:"+encryptstr) console.info("解密后:"+aesFun.decrypt(encryptstr)); </script> </body> </html>
