Cryptography is not a reason to use when posting photos on a public social media website.
Cryptography is the use of certain techniques that help protect important and personal information from being accessed by other parties. This technological practice or method allows a person to send sensitive or personal information over the internet without risking any "leak" of information.
Cryptography literally means "hidden writing", which is what the method is all about.
It presents a safe and secure way of sending or passing information, even personal or sensitive ones.
This technological method enables businesses and other companies as well as individuals to procure and send information without fearing for any loss of their information.
Cryptography is mainly used in the military, secret operations, businesses, or even in maintaining one's passwords while using social media platforms or submitting a password on a website.
One reason to not use it is when posting photos on social media websites as the website is to be used by the web world and may/can be accessed by everyone around the world.
Cryptography not only allows a person to maintain certain privacy and security but also help the smooth functioning of businesses and other national security works. Thus, cryptography is the "security" of individuals in the 'internet world'.
A useful advantage of Asymmetric encryption over symmetric
encryption is that there is no secret channel necessary for the
exchange of the public key, unlike in the symmetric encryption which requires a
secret channel to send the secret key.
Another
advantage of Asymmetric encryption is that is has increased security. Asymmetric
uses two different keys (Public and private) for both encryption and decryption
of data while symmetric uses one.
