PHP string encryption and decryption implementation process sharing

In our previous courseSeveral methods of php encryption and decryption, I believe everyone has a certain understanding and understanding of encryption and decryption, that is, an encrypted string is generated through the encryption algorithm. This encrypted character The string can be decrypted through the decryption algorithm, which facilitates the program to process the decrypted information. Today I will introduce to you the detailed implementation of PHP string encryption and decryption!

First download the PHP string encryption and decryption class library we need to use in this course: //m.sbmmt.com/xiazai/leiku/662

After the download is completed Find the php class file we need, unzip it to our local directory, and create a new php file!

After completion, we need to call this class in the new php file and instantiate the class:

en($str,$key)."
"; echo $cryption->de($str,$key)."
"; ?>

Run this file and get the result as shown below:

The above is the detailed content of PHP string encryption and decryption implementation process sharing. For more information, please follow other related articles on the PHP Chinese website!
