Consequently, it stops illegal access to information.
The prefix "crypt" in the word "cryptography" means "hidden," while the suffix "graphy" means "writing."
The methods used in cryptography to protect data are derived from mathematical ideas and a set of rule-based calculations known as algorithms to transform communications in ways that make them difficult to decode."
"These algorithms are used to create cryptographic keys, perform digital signature and verification, safeguard private data, safeguard web browsing on the internet, and safeguard private transactions like credit card and debit card use.
