About This Tool
The Bacon cipher is a classical substitution cipher that encodes letters into five-symbol sequences using A/B or 0/1. This tool supports the classic 24-letter variant (I/J, U/V merged) and the full 26-letter variant, with symbol format switching, case rules, grouping output, and a mapping table. Decryption can auto-detect input format, and all processing stays local in your browser.
