UtilsPark - Base64 Encode and Decode Tool

Expert in secure and efficient conversion between text and binary data

Base64 is a representation method that uses 64 printable characters to represent binary data. It is commonly used to transmit data in media that only allow ASCII characters, such as the transmission of binary files in email protocols. With Base64 encoding, any binary data can be converted into plain text format, ensuring the integrity and security of data during transmission.

Function Description:

1. Base64 Encoding Principle:
   • Divide the binary data into groups of 3 bytes, totaling 24 bits.
   • Divide these 24 bits into 4 groups, each with 6 bits.
   • Represent each group of 6 bits with the corresponding Base64 character, resulting in 4 Base64 characters.
   • If the length of the original data is not a multiple of 3, use the "=" character for padding.
2. Base64 Decoding Principle:
   • Split the Base64 characters into groups of 4.
   • Convert each group of Base64 characters back to the corresponding 6-bit binary number.
   • Reassemble the obtained 24-bit binary numbers into 3 bytes.
   • Remove the padding character "=" at the end to retrieve the original binary data.
3. Use Cases:
   • Embedding small icons or images within web pages.
   • Transmitting files in email attachments.
   • Transmitting binary data in URLs.
4. Advantages:
   • Ensures the integrity of data during transmission.
   • Avoids transmission errors caused by special characters.
   • Enhances the security of data transmission.
