One-way irreversible data encryption method and system

According to the one-way irreversible data encryption method and system, a part of a result value calculated through an MD5 encryption algorithm is removed through a modified MD5 algorithm, it is guaranteed that a generated result is not repeated, and the meaning of removing the part is that even if the encryption algorithm is obtained, the content cannot be restored. According to the method, some known plaintext file names or contents become unknown, irreversibility is achieved, and even if source codes in the encryption process are clarified, the original text cannot be restored. 本发明公开了一种单向不可逆的数据加密方法及系统，通过修改后自有MD5算法，通过MD5加密算法算出来的结果值再去掉一部分，保证生成后的结果不重复，去掉一部分的意义在于即使得到加密算法也无法还原出内容。使得一些已知的明文文件名或者内容变得不可知，实现不可逆，即使明确加密过程的源代码，也无法还原原文。
