Secure_Address_Book (with AES, Base64, MySQL)

• Data Structure: Linked List
• CRUD (Insert Update Delete Select)
• AES Encrpytion (AES-256, MODE= CBC, Padding= PKCS7)
• When program terminated, data in the linked-list is stored as a file.
• When program started, data in the file is loaded.
• Distinguish each person by ID
• Not normal text, save to Binary Data
• Makefile
• Shared Library

addr_book_db

• private data(phone number) : Base64 Encoded
• Add a menu to view the private data when authenticated by DB password
• Plain Text -> (AES-256/CBC) Encryption -> Binary Data -> (Base64) Encoding
• (Base64) Encoded Text -> Decoding (Base64) -> Binary Data -> Decryption (AES-256/CBC) -> Plain Text

$ make clean  
$ make  
$ ./addr_book
