Encode Mode

Description:

  • Encoding/decoding is based on UTF-8 text, supports URL-safe (+/= ↔ -_).
  • 76-column wrap is for RFC 2045 compatibility, removing line breaks is convenient for single-line use.
  • Error will be prompted when decoding incorrectly, existing output will not be overwritten; all calculations are done locally.
