Encryption is a crucial process in the field of information security, involving the conversion of data into a coded format that is unreadable to unauthorized individuals. This process ensures that sensitive information, such as personal data, financial details, or confidential communications, remains protected from unauthorized access or cyber threats. Encryption employs complex algorithms and cryptographic keys to transform plaintext, or readable data, into ciphertext, which appears as a random string of characters. Only those with the correct decryption key can convert the ciphertext back into its original, readable form. This technology is widely used in various applications, including secure online transactions, data storage, and communication systems, to maintain privacy and data integrity.
