πŸ” Base62 Working Principle

  • Character Set: 62 symbols 0-9, A-Z, a-z (total of 62 different characters)
  • Encoding Process: Interpret input bytes as large integers, convert to Base62 through repeated division
  • Decoding Process: Accumulate Base62 digits back to Base256 bytes (reverse process)
  • Variants: Some implementations rearrange the character set, ensure both parties use the same character set
  • Purpose: Base62 is a text representation for compact IDs/short links, not encryption
