CRYPTOGRAPHY
CRYPTOGRAPHY Cryptography: Safeguarding Information in the Digital Age Cryptography is the art and science of securing information by transforming it into an unreadable format, known as ciphertext, using mathematical algorithms. It plays a crucial role in ensuring the confidentiality, integrity, and authenticity of data in the digital age. Cryptographic techniques are employed in various areas, including online transactions, secure communication, data protection, and information security. Key Concepts in Cryptography: 1. Encryption: Encryption is the process of converting plaintext (readable data) into ciphertext (encrypted data) using an encryption algorithm and a cryptographic key. This ensures that even if unauthorized individuals gain access to the ciphertext, they cannot understand the original message without the corresponding decryption key. 2. Decryption: Decryption is the reverse process of encryption,...
