Caesar cipher Calculator encrypts entered text by using Caesar cipher. Non-alphabetic symbols (digits, whitespaces, etc.) are not transformed. |

Vigenère cipher Calculator encrypts entered text by using Vigenère cipher. Non-alphabetic symbols (digits, whitespaces, etc.) are not transformed. |

Hill cipher This calculator uses Hill cipher to encrypt/decrypt a block of text. |

Atbash cipher This calculator allows you to encrypt and decrypt text with Atbash method |

A1Z26 cipher 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 |

Pangram checker This online calculator can check if a phrase is a pangram. |

Rail fence cipher This article contains two calculators, first can be used to encode message with the rail fence cipher, second can be used to crack message encoded with the rail fence cipher by brute force. Decoded simply outputs decoded message for different number of "rails". |

Isogram checker This online calculator can check if a word/phrase is an isogram. |

PATHFINDER cipher checker This online calculator decrypts digits encrypted by PATHFINDER type of cipher. |

Playfair cipher This online calculator encrypts and decrypts a message given Playfair cipher keyword. Non-alphabetic symbols (digits, whitespaces, etc.) are ignored. |

Gravity Falls Bill's symbol substitution cipher decoder This online calculator can decode messages written with Bill's symbol substitution cipher |

Gravity Falls Author's symbol substitution cipher decoder This online calculator can decode messages written in the Author's symbol substitution cipher |

Pigpen cipher decoder This online calculator can decode messages written in the pigpen cipher |

Index of Coincidence This online calculator calculates index of coincidence (IC, IOC) for the given text |

Vigenère cipher breaker This online calculator tries to decode Vigenère cipher without knowing the key. It uses the index of coincidence technique. |

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. |

Substitution cipher decoder This online calculator tries to decode substitution cipher without knowing the key. It uses genetic algorithm over text fitness function to break the encoded text. Note that you may need to run it several times to find completely accurate solution. The calculator logic is explained below the calculator. |

Kasiski test This online calculator performs Kasiski examination of an entered text using trigrams in attempt to discover a key length |

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. |
