我取一個(gè)數(shù)據(jù)字符串 = "AkhilRanjanBiharabcdefghijklmnopMovedtoChennai18"，先加密然后解密。我解密后得到的字符串是“AkhilRanjanBiharù?+???à–y?ó@Movedto?hennai18”，這對(duì)于前 16 個(gè)和最后 16 個(gè)字符幾乎沒(méi)問(wèn)題，但中間的 16 個(gè)字符絕對(duì)是垃圾。什么可能會(huì)出錯(cuò)？我的加密代碼：-public String encrypt(String value) {    log.info("This method is not going to be used");    String key = "theabcd@heymaths";    initVector = "{{{{{{{{{{{{{{{{";    String encryptedStr="";    byte[] encrBytes =null;    try {        IvParameterSpec iv = new IvParameterSpec(initVector.getBytes());        SecretKeySpec skeySpec = new SecretKeySpec(key.getBytes(), "AES");        Cipher cipher = Cipher.getInstance("AES/CBC/NoPadding");        cipher.init(Cipher.ENCRYPT_MODE, skeySpec, iv);        encrBytes = cipher.doFinal(value.getBytes());        encryptedStr = new String(encrBytes);    } catch (Exception ex) {        ex.printStackTrace();    }    String strToBeEncoded = encryptedStr +"::"+initVector;    encrBytes = strToBeEncoded.getBytes();    //String encoded = Base64.encodeBase64String(encrBytes);    String encoded = Base64.getEncoder().encodeToString(encrBytes);    String urlEncoded = null;    try {        urlEncoded = java.net.URLEncoder.encode(encoded, CHARSET);    } catch (UnsupportedEncodingException e) {        // TODO Auto-generated catch block        e.printStackTrace();    }    return urlEncoded;}解密代碼：-public String decrypt(String encrypted) {    String decryptedStr = null;    byte[] base64Bytes = null;    String urlDecoded = null;    String key = HmCommonProperty.getProperty("abcd_crypt_key");    if(key == null || key.isEmpty()) {        key = securityKey;    }    String encryptionMech = HmCommonProperty.getProperty("abcd_crypt_algo");    if(encryptionMech == null || encryptionMech.isEmpty()) {        encryptionMech = CRYPT_MECHANISM;    }    return decryptedStr;}
