About jQuery implementing base64 front-end encryption and decryption function
This article mainly introduces jQuery's implementation of base64 front-end encryption and decryption functions. It analyzes the implementation method of jquery.base64.js to implement front-end base64 encryption and decryption functions in the form of examples, and gives a comparison of operation examples of java's implementation of back-end base64 encryption and decryption. To verify the encryption effect, friends who need it can refer to it. I hope it can help everyone.
Regarding encryption, many people think of encodeURI and escape. This is useful for encrypting URLs, especially URLs with Chinese parameters.
If you just want to do encryption and decryption, similar to Java's DES, jQuery on the Internet has jquery.base64.js.
(For md5 encryption of js, you can use jquery.md5.js. If you are interested, you can find it and test it).
The following is the test:
