XOR Encryption is an encryption method used to encrypt data and is hard to crack by brute-force method, i.e generating random encryption keys to match with the correct one. ... To decrypt the encrypted characters we have to perform XOR operation again with the defined key. Here we are encrypting the entire String.

Why XOR is used for encryption?

The XOR property (a xor b) xor b = a comes in handy for stream ciphers: to encrypt a n bit wide data, a pseudo-random sequence of n bits is generated using the crypto key and crypto algorithm. XOR is more subtle you can't know for sure the value of any bit of the result, whatever the mask you choose.

What type of encryption is XOR encryption?

The XOR encryption algorithm is an example of symmetric encryption where the same key is used to both encrypt and decrypt a message. Symmetric Encryption: The same cryptographic key is used both to encrypt and decrypt messages.
