19-May-2023Cryptography is the practice and study of techniques for secure communication in the presence of third parties or the public. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages. Cryptography is a branch of mathematics that deals with the study of secret codes and ciphers.
Cryptography is used in a wide variety of applications, including:
Cryptography is an important tool for protecting data from unauthorized access. By using cryptography, you can help to keep your data safe from hackers and other criminals.
There are two main types of cryptography: symmetric encryption and asymmetric encryption.
There are many different cryptographic algorithms, but some of the most common include:
Cryptography is a complex and ever-evolving field. As new threats emerge, new cryptographic algorithms are developed to protect against them. Cryptography is an essential tool for protecting data in the digital age.

Cryptography is a technique of converting information in such a format that it is not accessible by unauthorized user without anyone decoding it back into a readable format,thus compromising the data.
This is made by Crytology: Cryptography + Cryptoanalysis .
Vision of crypto: classic and Modern Cryptography.
Modern cryptography is the cornerstone of computer and communications security. The goal of modern cryptography is to ensure the preservation of information properties through mathematically perform. Cryptography involves the process of encryption and decryption.
Objectives of cryptography:-
1- Confidentiality
2- Integrity
3- Authentication
4- Non-repudiation
Cryptography primitives:-
-Encryption
-Hash functions
-Message authentication
-Digital signatures.
Cryptocurrency :
The Cryptocurrency in which encryption techniques are used to perform the generation of units of currency and verify the transfer of funds,operating independently of any bank.
