About this tool
Atbash replaces the first letter with the last, the second with the second-last and so on. The same operation encodes and decodes because the mapping is symmetrical.
Choose the Latin or Polish alphabet. Case, spaces, numbers and punctuation remain unchanged. This is a puzzle and education tool, not secure encryption.
