dsh-caesar

When you need to encrypt or decrypt a short piece of text right inside a conversation, the default instinct is to hit an external API or a cloud function. dsh-caesar offers a different path: it runs the classic Caesar cipher entirely on your local Node runtime, with zero network calls and zero external services, so your plaintext never leaves the machine.

Its scope is deliberately narrow and transparent: once registered as a session tool, you simply invoke it in-chat to perform Caesar encryption or decryption on any string. No server to stand up, no key store to configure, no async callbacks to chase. The pure-Node implementation means no binary dependencies and fully deterministic, offline-reproducible behaviour.

It is well suited for developers who want to quickly obfuscate keywords or short phrases in a chat, instructors who teach classical cryptography in a live session, and security-minded users who prefer not to hand any plaintext to a third-party API. Lightweight, auditable, and MIT-licensed — skim the source for two minutes before you rely on it.
