The role of encryption in securing communications is to protect sensitive information from unauthorized access by converting data into a coded format that can only be deciphered with a specific key. This ensures confidentiality and integrity during transmission, as even if data is intercepted, it remains unreadable. Encryption is vital for securing online transactions, email communications, and personal data storage. It is a fundamental component of modern cybersecurity strategies, safeguarding against eavesdropping and data breaches. Consequently, implementing strong encryption protocols is essential for maintaining trust in digital communications.
