Common usage of Base64

  • Encode binary data so it can be included in data: URL. Like embedded images in HTML, CSS or attachments in emails.
  • Output binary data as XML or JSON in API responses
  • Preserve raw bytes of cryptographic functions
  • Save binary files to database when BLOB is unavailable
  • Hide plain secrets from being seen (bad practice) like for Basic HTTP Authentication
