AES加解密范例

• 加密

public static String encrypt(String sSrc, String sKey) {
        if (sKey == null) {
            return null;
        } else if (sKey.length() != 16) {
            return null;
        } else {
            try {
                byte[] raw = sKey.getBytes("utf-8");
                SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");
                Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
                cipher.init(1, skeySpec);
                byte[] encrypted = cipher.doFinal(sSrc.getBytes("utf-8"));
                return Base64.getEncoder().encodeToString(encrypted);
            } catch (Exception var6) {
                log.error("encrypt get sign error", var6);
                return "";
            }
        }
}

• 解密

public static String decrypt(String src, String key) {
        try {
            src = src.replace(" ", "+");
            if (key != null && key.length() == 16) {
                byte[] raw = key.getBytes("utf-8");
                SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");
                Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
                cipher.init(2, skeySpec);
                byte[] encrypted1 = Base64.getDecoder().decode(src);
                byte[] original = cipher.doFinal(encrypted1);
                String originalString = new String(original, "utf-8");
                return originalString;
            } else {
                return null;
            }
        } catch (Exception var8) {
            log.error("decrypt get sign error", var8);
            throw new LogicException(ResultCode.ERROR_AES, new String[0]);
        }
    }
