Use this decoder when the input is known to use the named encoding or classical cipher and you need to recover its bytes, symbols, numbers, or text deterministically.

taps

Groups of two digits 1-5, words separated by spaces (e.g. "11 34 15").

Decode digit-pair tap groups into text. 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]

text

Decoded uppercase text.

bad

Indices of malformed or out-of-range groups.

• Decoding cannot reliably identify an unknown format or repair arbitrary corruption. Alphabet variants, padding, whitespace, character encodings, byte order, framing, cipher keys, and malformed-input policies must match the producer.
• 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.

Confirm the format from metadata or a specification, preserve the original input, and validate decoded length or checksums where available. Treat decoded untrusted content as data rather than executable markup or code.

• Bacon Cipher Decoder

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

• Base122 Decoder

  Decode Base122 artifact text into UTF-8.

• Base32 Decoder

  Decode canonical RFC 4648 base32 text back into UTF-8, rejecting misplaced padding and non-canonical bits.
