Key Concepts in Cryptographic Solutions

Cryptography is the science of encoding and decoding information to protect it from unauthorized access. At its core, cryptographic solutions rely on mathematical algorithms and keys to transform plaintext into ciphertext and vice versa. Key concepts include:

• Encryption and Decryption: Encryption converts plaintext into ciphertext using an algorithm and a key, while decryption reverses the process.
• Symmetric and Asymmetric Cryptography: Symmetric cryptography uses the same key for encryption and decryption, while asymmetric cryptography employs a pair of keys (public and private).
• Hash Functions: These are algorithms that generate a fixed-size output (hash) from input data, ensuring data integrity.
• Digital Signatures: A cryptographic technique that verifies the authenticity and integrity of a message or document.
• Key Management: The process of generating, distributing, storing, and revoking cryptographic keys securely.
