WebSHA256 uses a block size of 512 Bit = 64 byte and resulting digest is 256 Bit = 32 byte long. You can also use your own block size and outcome size but for a realistic approach we stick to the original sha256 standard. Now we need to implement the init, update, final and copy functions for our own sha256 implementation. Web你是在要求这些文件之间的差异，还是这些文件与阶段之间的差异？@folkol我在寻找这些文件与阶段之间的差异查看我的答案，并在那里询问是否有不清楚的地方。
