Read a file in chunks in Python This article is just to demonstrate how to read a file in chunks rather than all at once. This is useful for a number of cases, such as chunked uploading or encryption purposes, or perhaps where the file you want to interact with is larger than your ma...
AES:Advanced Encryption Standard,支持的秘钥长度包括 128bits,192bits,258bits,384bits,512bits。 需要说明的是,秘钥长度越长,数据加密与解密的时间就越久。 特点: 加密与解密使用的密钥相同。 但是由于算法一般都是公开的,因此机密性几乎完全依赖于密钥。
