Answers to Questions

How to encrypt using XOR cipher?

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 repeated 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 back the first bit.

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

How to decrypt XOR cipher?

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

1001 ⊕ 1010 = 0011 and 0011 ⊕ 1010 = 1001

How to convert a text in binary?

dCode uses the ASCIIhref table that associates to latin alphabet letters a number between 0 and 128, which is then converted in base 2href (binary). It is possible to use other methods to get binary encoded text.

What is the truth table for XOR?

ABA xor B
000
011
101
110

How to recognize XOR ciphered text?

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

How to decipher XOR without key?

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.

What are the variants of the XOR cipher?

One can imagine to apply XOR with the principle of an Autoclavehref ciphering.
