    Noa says ...

    Cryptography is a method to exchange information secretely between the sender and the recipient.

    Franck says...

    I think cryptography is very important because if a person doesn't want to expose his or her life. She or he is not obligated.

    Cryptography is something you use if you want to comunicate with someone without somebody else to intercept and so understand the message. It has mainly been used during wars. The ciphered text is the text you get after ciphering a plain text. To get the plain text from the ciphered text, you have to decipher it and to do it you need a key.

    mona says...

    Cryptography is a way to cipher text with a key. It's for communticate with an other person without someone else to understand it. This is important to today's world because there are many wars and secrets between some countries and it's important for them to be the only ones to understand the message.

    Anxhelo says....

    CRYPTOGRAPHY: enable us to store and transmit information while safeguarding it from intruders. CRYPTOGRAPHY achieves this by converting data in to a different form.

    Denis says...

    Cryptography is the technique of hiding and securing data or information during transmission from one person or group to another.
    Cryptography converts information or data into an unreadable format, so it can’t be compromised or read unless you are the person it was meant for.

    Marco says...

    Cryptography is a method for protecting information through the use of codes, in these way only the persons that know how to decrypt the message are able to read it.

    Riccardo M. says...

    -What is cryptography?
    Cryptography is a method of transmitting a secret message to another person, whithout a tird person being able to intercept the message, can understand it.

    -Today encryption is important because protect sensitive information

    Lorenzo

    Cryptography is the practice or study of techniques for secure communication in the presence of third parties. Cryptography is about constructing and analyzing protocols that prevent third parties from reading private messages. Various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation are central to modern cryptography.

    Thomas B

    Encryption is the process through which data is encoded so that it remains hidden from or inaccessible to unauthorized users. It helps protect private information, sensitive data, and can enhance the security of communication between client apps and servers. In essence, when your data is encrypted, even if an unauthorized person or entity gains access to it, they will not be able to read it.

    Nicola Rm. says..

    -What is cryptography?
    Encryption is one of the methods for transmitting, sending a secret message to a person, without another person being able to intercept the message and understand it.
    -Why is cryptography important in today's world?
    Cryptography is important today because it allows you to protect all sensitive information. For example, Cryptography ( end-to-end) protects the calls and messages that we send on WhatsApp.

    Cesare F.

    >What is cryptography?
    Cryptography is the science that studies the methods
    to hide a message to make it incomprehensible to unauthorized people to read it.
    It converts data from a readable format into an encoded format that can only be read after it has been decrypted.

    >Why is cryptography important in today's world?
    Cryptography is a fundamental tool to protect data, stored or in transit, from unauthorized access.

    Conventional writing secret, decipherable only by those who are aware of the code

    Jacopo says

    Encryption is now important in the telecommunications industry and in applications that require high data protection. Encryption also serves to protect transmitted data by preventing them from being altered or stolen by attackers and authenticating a user

    EmanueleC

    1)What is cryptography?

    encryption is a method of protecting messages that we don't want to be read. cryptography was used extensively in the military to exchange information without being discovered by enemies.
    2)Why is cryptography important in today's world?
    With the spread of the network and the exchange of files and messages via e-mail, you are subject to risks, especially these can be intercepted by other users or hackers who can get hold of personal data and files. It therefore becomes important to protect sensitive data from third parties and protect yourself securely, which is why encryption is very important nowadays.
