Issecret = 1 o'clock to proceed.Encrypted reading is to prevent others from sniffing the key on the bus, and here I borrow a picture from the official document Atmel-8981This flowchart is really clear, the main steps are as follows:1, first send nonce command command

This article is an example of the development of the PHP micro-trust to obtain information about the surrounding hotel methods. Share to everyone for your reference. The specific analysis is as follows: Attention to micro-letter public after sending a response to geographical information, you can reply to the surrounding hotel information list, I would like to give you an introduction to the use of PHP how to achieve this function, I hope all the children to help. The code is as follows:

the HttpHandler. 1) Verifying signatures If this is the first request, you need to verify the signature. is equivalent to an HTTP handshake. Previously in the previous chapter, set the server URL and the token value, this function is to verify that the link is successful. This request is a GET request. The following specific description (official): Business logic: Encryption/validation Process: But the official only provides the PHP code example, many things in C # are not literal t

On the subject, Sina Weibo recently updated the SSO login method, and the encryption algorithm changed to RSA to obtain nonce, servertime, and pubkey. RSA encryption is involved here, generally, RSA encryption in Java is performed by reading the public ke
