#cw

Morse code conversion as an API, computed locally and deterministically. The encode endpoint turns text into International Morse code, mapping A–Z, the digits 0–9 and common punctuation to dots and dashes, separating letters with a space and words with a slash, and listing any unsupported characters it skipped. The decode endpoint turns Morse code back into text, accepting word separators written as a slash, a pipe or a wide gap, and marking unrecognised symbols. The timing endpoint computes the PARIS-standard timing from a words-per-minute speed — the dot duration is 1200/WPM milliseconds, a dash is three dots, and the gaps are one, three and seven dot units for intra-character, inter-character and word spacing — and, given a Morse message, the total number of units and the transmission time. The word PARIS is exactly 50 units, which defines the WPM scale. Everything is computed locally and deterministically, so it is instant and private. Ideal for amateur-radio, aviation, education, accessibility, puzzle and game app developers, signalling and CW-training tools, and learning Morse. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is Morse code; for Base64 and JWT use an encoding API and for Caesar and substitution ciphers a cipher API.
