0 Today we will focus on front-end encryption. Some projects involve more sensitive data, and developers will require the front end to encrypt the data before transmitting it to the back end for decryption processing. Although https has actually played a great role in protecting data transmission, for users who do not use https, front-end encryption still has a certain significance.
This article involves:
The front end uses CryptoJS to encrypt and decrypt DES or AES data;
The backend uses PHP openssl to decrypt and encrypt the data.
