Base64 Encode Decode Tool

Introduction

When writing code, I often need to encode and decode data from interfaces using Base64, so I wrote this tool. Other use cases include: when posting on forums and leaving an email address, it is common to also process it with Base64 encoding to avoid being crawled by bots. When transmitting data in URLs, Base64 encoding can ensure that special characters are handled correctly to avoid data corruption. The size of the data after Base64 encoding will be about 33% larger than the original data, and since there is no encryption during transmission, it does not provide security or privacy protection for the data.
