通过对OpenSSL对称密码算法函数的调用，实现常用的对称加密。这个工具主要的功能已经实现，而且还可以对大文件进行加密，可能效率上还需进一步完善，因为对大文件加密时，太差劲的电脑会感觉有点卡！另外，它还可以对电影加密，不妨一试。-Symmetric cryptographic algorithm through OpenSSL function calls to achieve common symmetric encryption. The main function of this tool has been achieved, but also can encrypt large files, you may need to further improve efficiency, because the large file encryption, too bad the computer will be felt Dianka! In addition, it can encrypt the film, worth a try.
