Abstract—
The process of converting the initial text communication
into an ambiguous form, as well as in reverse, is known
as cryptography. It is the process of concealing data and
transmitting it in an appropriate format so that only
authorized individuals may access and use it. Data
security for consumers is mostly achieved through the use
of cryptographic processes, which protect data against
theft or transformation. This paper defends the use of
