OTPEncryption

• The internet is an open and public system we all send and receive information over shared wired and connections .We also exchange a lot of private data like credit card numbers, bank information, passwords and emails .
• Data of any kind can be kept secret through a process known as encryption .Which is defined as encrypting or changing of the message to hide the original text.
• Decryption is the process of unscrambling that message to make it readable .
• One of the first well-known methods of encryption was caesar's cipher,named after julius caesar, A roman general who encrypted his military commands to make sure that if a message was intercepted by enemies, they wouldn't be able to read it.
• Each encryption algorithms has a key allows the sender to encrypt the message and the receiver to decrypt the message.
• There are two types of encryption symmetric and asymmetric.
• When the sender and the receiver share the same key to scramble and unscramble a message . it's called symmetric encryption like caesar's cipher.
• When there's public key to encrypt data but the encrypted message can only be decrypted by computer with access to the private key. It's called asymmetric encryption.
• Our project is about one-time pad encryption (OTP) which is symmetric encryption .
• OTP is an encryption technique that cannot be cracked, but it requires the following
  • 1- Random key that is as long as the message.
  • 2- The key is to be used to encrypt and decrypt a single message and then it is discarded.
  • 3- The key must be securely shared between the sending and receiving parties.
