Answers to Questions

How to encrypt using XOR cipher?

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

Example: The plain message is 1001 and the key is 10

Take the first bit (0 or 1) of the plain text and the first bit of the key and multiply then using XOR operation to get the ciphered bit.

Example: 1 ⊕ 1 = 0

The operation is repeated with the second bit of the plaintext and the second bit of the key. At the end of the key, loop back to the first bit.

Example:

Plain message
1001
Key (repeated)
1010
Encrypted message
0011

How to decrypt XOR cipher?

XOR Decryption is identical to encryption because the XOR operation is symmetrical (reverse XOR = XOR).

Example: 1001 ⊕ 1010 = 0011 and 0011 ⊕ 1010 = 1001

How to convert a text in binary?

dCode uses the ASCII table encoding which associates with characters (including the letters of the alphabet) a number between 0 and 128, which is then converted to base 2 (binary). It is possible to use other methods to get binary encoded text.

What is the truth table for XOR?

The truth table of the 2-parameter XOR logic function is:

ABA xor B
000
011
101
110

How to recognize XOR ciphertext?

A xored messaged (XOR encrypted message) has no particularities, this makes it hard to detect.

It can be presented under binary form but also as ascii text.

Data in the form of a stream is well suited to XOR encoding.

How to decipher XOR without key?

Xor decryption without key is hard. 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?

XOR is compatible with the principle of an Autoclave ciphering.
