Explanation: Decryption is the process of converting encrypted data (ciphertext) back into its original readable form (plaintext) using a cryptographic key or algorithm. This process allows authorized users to access secure information. Decryption plays a critical role in secure communications, as it ensures that sensitive data transmitted over networks can be safely retrieved and understood…
Explanation: Cryptography is the science of securing information by transforming it into an unreadable format using mathematical algorithms. This ensures that only authorized individuals can access and understand the information. The primary goals of cryptography are confidentiality, integrity, authentication, and non-repudiation. Cryptographic techniques are commonly used in secure communications, online transactions, and data storage. Modern…
