Cryptography provides a way to distribute files in secret code or cipher, so they can only be read by intended recipients. Cryptography ensures data integrity and secure communication in your Windows-CE based application.
2. What is encryption/decryption?
Encryption is the process of encoding data into cipher, a form unreadable without a decoding key. Decryption is the reverse process of converting encoded data to its original plain text form. When a user encodes a file, another user cannot decode and read the file without the decryption key. Adding a digital signature, a form of personal authentication, ensures the integrity of the original message.
3. What is Symmetric Key Encryption?
Symmetric Key Encryption is the most common type of encryption and uses the same key for encrypting and decrypting data. This key is known as session key.
