Use this encoder when a receiving system, file format, protocol, puzzle, or historical cipher explicitly requires the named representation and its alphabet or key convention is known.

text

Plain text; K is encoded as C.

Encode text into digit-pair tap groups. Classic POW tap-code grid omits K (use C). The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

taps

Space-separated digit pairs per word.

letters

Encoded letter count.

• Encoding changes representation, not trustworthiness or meaning. Alphabet variants, padding, line wrapping, character encoding, byte order, unsupported characters, and malformed Unicode can affect interoperability; classical ciphers and checksums do not provide modern confidentiality or authenticity.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Round-trip representative values through the matching decoder and verify published test vectors where available. Use authenticated encryption for security and a cryptographic hash or MAC when integrity against an adversary is required.

• Base85 Encoder

  Encode UTF-8 text as Ascii85 (base85), using z for zero groups.

• URL Component Encoder

  Percent-encode text for use as one URL component.

• Bacon Cipher Encoder

  Encode letters A–Z into five-symbol Bacon cipher groups.
