Encryption Techniques

Cryptography is the practice of using techniques to ensure secure communication in the presence of adversarial behavior. Encryption is a cryptographic technique that converts data into an unintelligible format, known as ciphertext. Decryption is the reverse process, where ciphertext is converted back into its original, readable format, known as plaintext.

Why Learn Encryption Techniques?

Encryption techniques are essential for protecting sensitive information in various domains, including:

• Data security: Encrypting data at rest or in transit ensures its confidentiality and integrity.
• Privacy: Encryption safeguards personal and sensitive information from unauthorized access and disclosure.
• Cybersecurity: Encryption is a fundamental defense mechanism against cyber threats such as data breaches and malware attacks.
• Digital communication: Encryption enables secure communication over networks, protecting emails, messages, and other forms of digital exchange.
• Financial transactions: Encryption protects financial data, such as credit card numbers and banking information, during online transactions.
