Data encryption is a crucial technique used to protect sensitive information from unauthorized access. By converting data into a coded format, encryption ensures that even if intercepted, the information remains unreadable without the proper decryption keys. This process is vital for securing communications, financial transactions, and personal data. Various encryption algorithms exist, such as AES (Advanced Encryption Standard) and RSA, each with different levels of security depending on the context. Implementing strong encryption practices is essential for organizations to comply with data protection regulations and maintain customer trust.
