How to use Base32 / 58 / 85
- 1. Paste text. Or drop a small text file.
- 2. Pick an alphabet. Base32, Base58, or Ascii85.
- 3. Encode or decode. Decode expects the matching alphabet.
- 4. Copy. Local only.
About this tool
Base64 is not the only wire alphabet. TOTP secrets are Base32. Bitcoin addresses are Base58. PDFs used Ascii85. This tool covers those three without a server.
Base58 vs Base64
Base58 drops 0/O/I/l so humans misread less. It is not RFC 4648.
Padding
Base32 uses = padding. Ascii85 uses <~ ~> delimiters on encode.
