Encryption is the process of converting readable data into an unreadable format, known as ciphertext. This process involves four key entities: a file, an encryption algorithm, a cryptographic key, and an output file. An encryption algorithm, such as AES-256 or RSA, determines the rules for transforming the input file into ciphertext. The cryptographic key is a string of characters that specifies the specific encryption rules used by the algorithm. The resulting output file contains the encrypted data, which can only be decrypted with the correct key and decryption algorithm.
