Today, when using Laravel to write something, you need to interact with the front end, look at the JWT (JSON Web token), and then t

PHP RSA Encrypted Transport code sample When it comes to transmission of sensitive data, it is best for both parties to use cryptographic decryption. RSA Asymmetric encryption is a promising one. The server can keep its private key and send it to the client's corresponding public key. So that we can decrypt each other.

1. The first step in encrypting decryption is to generate a public key, a private key pair, and a private key to encrypt the contents through the public key (can be reversed) Download the open source RSA key generation tool OpenSSL (usually the Linux system comes with the program), unzip to a separate folder, enter the Bin directory, and execute the following command: The code is as follows: OpenSSL genrsa

1. There's a tricky problem today, where you write down blogs that remind yourself and help people who are going to be in trouble. In the Shiro framework, you can login directly in your code with a username password. First looked up on the internet, found this way: Subject CurrentUser = Securityutils.getsubject (); Usernamepasswordtoken token = new Usernamepasswordtoken (Username,password, false,reques

=128byte;If the encrypted PADDING Fill method chooses Openssl_pkcs1_padding (which takes 11 bytes), the clear text length can only be 128-11=117 bytes. If exceeded, then these OpenSSL decryption functions will return false.At this point, the solution is to separate the source strings that need to be encrypted into groups of less than 117 lengths, divided into groups of 172 bytes at the time of decryption.Where the "less than 117" (as long as not more than 117) and "172" two numbers is how to com
