Base64란?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It converts binary data into a set of 64 printable characters (A-Z, a-z, 0-9, +, and /), with = used for padding.

어떻게 작동하나요?

Base64 encoding works by taking groups of three bytes (24 bits) of binary data and splitting them into four groups of six bits each. Each 6-bit group is then mapped to one of 64 printable ASCII characters.

왜 Base64인가요?

Base64 encoding is essential in many areas of software development. It is used to embed images in HTML/CSS, transmit binary data over text-based protocols like email (MIME) and HTTP, store data in JSON/XML formats, and encode authentication credentials.

일반적인 용도

  • Embedding images in HTML/CSS using data URIs
  • Sending email attachments via MIME encoding
  • Encoding binary data in JSON and XML payloads
  • HTTP Basic Authentication credentials
  • Storing binary data in text-based databases
  • Data transfer between different systems and platforms
