Transferring files from a computer to the Internet or from a computer to another one is a common task. However, ensuring security and safety is of a great issue. Encryption And Decryption is an application to decrypt and encrypt sensitive messages, documents and files. Symmetric Encryption or private key encryption enables to encrypt and decrypt information. For that, the software uses a secret key can be a number, a word, or just a string of random letters aiming at changing the content in a particular way. This process requires the sender and the receiver to know the secret key to be able to encrypt and decrypt all information.
Selected by NIST as a Federal Information Processing Standard in November 2001 (FIPS-197), it's AES 256-bit key encryption offers complete protection to your data. A hash (SHA 256) is used to protect the encryption key. If Encryption and Decryption detects a wrong password, it will be impossible to get the encryption key. Users can use a Public Key Encryption so that anyone can encrypt a message. Nevertheless, the decryption key remains private so as to let the receiver decrypt the message.
