2024-12-05 00:00:00 Crypto Encrypt and Decrypt refer to the processes of converting data into a secure format to protect it from unauthorized access (encryption) and reversing it back to its original form when needed (decryption). Encryption transforms plaintext data into ciphertext using an algorithm and a key, making it unreadable without the correct key. Decryption uses a key to convert the ciphertext back to its original plaintext. These processes are essential in data security for safeguarding sensitive information in communication, storage, and online transactions.
