Calculator encrypts entered text by using Vigenère cipher. Non-alphabetic symbols (digits, whitespaces, etc.) are not transformed.
This calculator uses Hill cipher to encrypt/decrypt a block of text.
A1Z26 is very simple direct substitution cypher, where each alphabet letter is replaced by its number in the alphabet.
|Standard Galactic Alphabet decoder
This online calculator can decode message written with standard galactic alphabet symbols
|Substitution cipher tool
A tool to encrypt/decrypt messages with a simple substitution cipher given as the key. It is also useful for manual cryptanalysis of a substitution cipher - when you have a message written in the English alphabet partially decrypted with an automatic tool and want to tweak the key.
|Automated Vigenère cipher decoder
This online calculator provides aid in finding Vigenère cipher key if you can guess part of the encrypted text. It just automates some routine calculations, which you would perform manually otherwise.
This online calculator allows users to encode and decode messages using the A2Z52 cipher.
