Cryptography is the practice of securing information by converting it into an unreadable format using mathematical algorithms.
The basics of cryptography include understanding encryption, decryption, keys (symmetric and asymmetric), hash functions, and digital signatures.
Cryptography ensures confidentiality, integrity, authentication, and non-repudiation in data communication.
It is widely used in network security, online banking, SSL/TLS, and secure messaging to protect sensitive information from unauthorized access and cyberattacks.
Basics of Cryptography
1: Encryption/Decryption.
2: Hashing.
3: Encoding/Decoding.
4: Symmetric and Asymmetric.
5: Public key infrastructure.
6: Block ciphers and stream ciphers.
7: Public key and private key.
8: Vulnerable ciphers/algorithms.
