After three days of exploration, we finally succeeded in using known byte [] data to generate a bitmap (256-color grayscale BMP Bitmap ). Many problems are encountered: How to operate bitmap in C # (GDI +) to obtain various bitmap data, just like in C ++ | How to modify the bitmap palette How to solve the bitmap display dislocation problem, that is, the bitmap 4-byte alignment problem How to use data to generate bitmap To sum up, we hope to help our f

using OpenSSL to generate SHA-256 self-signed certificates that are available for IIS Well, 2017 iOS will start to force ATS, so all the sites, APIs, Web pages, resource paths and so on need to use TLS1.2 above standards.Self-signed certificates have not been able to meet the requirements. Therefore, in the formal environment to apply for the purchase of OA certificate. So you don't have to spend money on a test environment to buy a certificate, so y

Micro framework provides the ability to access the Internet. In terms of data security, micro framework only supports RSA and xtea algorithms. Due to the communication needs of heterogeneous systems, I have compiled an Encryption Class Library, which currently only implements SHA-1, SHA-256 algorithm, and will be improved later. See http://www.microframework.cn/post/2009/03/16/SHA-Algorithms-On-Micro-Framework.aspx The code can be downloaded here: s
