String inputDecryptData = "";
        try {
            Object privateKey = redisUtil.get(Constant.RSA_PRIVATE_KEY);

            inputDecryptData =  RSAUtils.decrypt(password.replaceAll(" ","+"), RSAUtils.getPrivateKey(privateKey.toString()));
        } catch (Exception e) {
            log.error("RSA encryption and decryption exceptions occurred ======>", e);
            throw new BizException("RSA encryption and decryption exception occurred");
