Tool to decrypt/encrypt with XOR automatically. XOR Cipher is a cryptographic method developped with computers. Is consists in encrypting a binary message with a repeated key using a XOr multiplication.

Encryption uses the XOR operator (Exclusive Or, symbol : ⊕) with the plain text and the key as operand (that should be binary encoded).

Let the plain message be 1001 and the key 10

One take the first bit (0 or 1) of the plain text and the first bit of the key and the one multiply with XOR to get the ciphered bit.

1 ⊕ 1 = 0

The operation is epeated with the second bit of the plaintext and the second bit of the key. If we get to the end of the key, one takes bak the first bit.

0 ⊕ 0 = 0, puis 0 ⊕ 1 = 1 puis 1 ⊕ 0 = 1. The ciphered message is 0011.

Decryption is identical to encryption because the XOR operation is symmetrical.

1001 ⊕ 1010 = 0011 and 0011 ⊕ 1010 = 1001

A | B | A xor B |
---|---|---|

0 | 0 | 0 |

0 | 1 | 1 |

1 | 0 | 1 |

1 | 1 | 0 |

A XOR ciphered message has no particularities, this makes it hard to detect. It can be presented under binary form but also as ascii text.

It is possible to find all or a part of the key by knowing a part of the plain text.

Else, there are no practical methods other than trying all the keys.

One can imagine to apply XOR with the principe of an Autoclave ciphering.
