CRYPTOGRAPHY

Explore the fascinating world of secure communication, encryption and data protection.

01

What is Cryptography?

Cryptography is the science of protecting information by transforming it into a secure form so that only authorized users can access it.

It plays an important role in secure communication, online transactions, authentication and data protection.

Secure Information

Protecting data from unauthorized access, modification and misuse.

02

Why is Cryptography Important?

Confidentiality

Keeps sensitive information accessible only to authorized users.

Integrity

Helps ensure that information is not altered without authorization.

Authentication

Helps verify the identity of communicating parties.

Non-Repudiation

Helps prevent denial of legitimate actions or transactions.

03

Key Concepts

01

Encryption

Converting readable data into an encoded form.

02

Decryption

Converting encrypted data back into its original form.

03

Authentication

Verifying the identity of a user or system.

04

Digital Signature

Used to verify authenticity and integrity of digital information.

04

Types of Cryptography

01

Symmetric Cryptography

Uses the same key for both encryption and decryption.

Example: AES
02

Asymmetric Cryptography

Uses a public key and a private key for secure communication.

Example: RSA
03

Hash Functions

Converts data into a fixed-length hash value.

Example: SHA-256
