摘　　要：将文件内容读取并转换为字符串,然后按照一定的策略规则将字符串中的部分或全部字符提取出来,利用原文和密钥之间比特位的逻辑运算关系对字符编码加密,可实现磁盘文件的加密。根据实际需要对加密策略加以调整,通过在安全性和效率之间进行权衡取舍,可以对加密算法进行增强或减弱,从而满足不同场景的应用需要。The file content is read and converted into a string,and then some or all characters in the string are extracted according to certain policy rules,and the characters's codes encrypted using the logical operation relationship between the original text and the keyt,which can realize the encryption of the disk file.Adjust the encryption strategy according to the actual needs.By balancing the security and efficiency,the encryption algorithm can be enhanced or weakened to meet the application needs of different scenarios.
