The RC4 extender is used to encrypt or decrypt a line of text using RC4 encryption.

When RC4 scrambles a string the result may contain binary values.
These values cannot be saved in a WinBatch string variable.
To allow WinBatch to do encryption, the scrambled value is returned as a string
of hexadecimal numbers.
(Since each byte of a string requires two hexadecimal digits,
the output will be twice as long as the plain text.)
The decryption expects its input to be in this same hexadecimal notation.

Another option is to encrypt and decrypt in a binary buffer.
Since a binary buffer can contain any data there is no need to
"hexadecimalize" the encrypted text.
However, you can only manipulate the data in the buffer,
you cannot copy it to a string variable.
