What is encryption?
- The process of compressing data for storage
- The process of converting plaintext into ciphertext using algorithms
- The process of indexing data for faster retrieval
- The process of validating data integrity
Encryption is the process of converting plaintext (ordinary, readable data) into ciphertext (encoded, unreadable data) using cryptographic algorithms. It ensures that unauthorized users cannot access or understand the information without the appropriate decryption key, thereby maintaining data confidentiality and security. Encryption is crucial for safeguarding sensitive information during transmission and storage.
