What is Base64 Encoding?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's used to transmit data safely over channels that might not support all binary characters.

How Base64 Works

  • It converts binary data into a sequence of 6-bit blocks.
  • Each 6-bit block is then mapped to a corresponding character from the Base64 alphabet, including A-Z, a-z, 0-9, +, and /.
  • The = character is used for padding when the input is not a multiple of 3 bytes.

Common Uses of Base64

  • Data URLs: Embedding images or other resources directly into HTML or CSS files.
  • Email Attachments: Encoding binary files as text for transmission via email.
  • API Requests: Passing binary data as part of a text-based API request (e.g., in JSON or XML).

Base64 vs. Other Encoding Schemes

Unlike encryption, Base64 is simply an encoding scheme, not a security measure. It's designed to represent data in a text format, not to protect it from unauthorized access. To secure data, use encryption algorithms like AES Encrypt or DES Encrypt.
