Family is clicked on and can pop up prompting when sharing user is allowed to be confirmed whether file being encrypted, if user be not required to encryption can directly by
Picture is shared away according to normal flow, if user needs to encrypt, file can be encrypted by algorithm, while from
Dynamic generation key, so-called key is exactly to be prompted to user in the form of letter, number or additional character, at this point, picture file
Become encryption file.
Secondly, by encryption sharing files to other users, other users can not be checked normally after receiving this document, be used
Family also needs key being individually sent to recipient.
Finally, recipient, which clicks on encryption file, can prompt input key, can normally be checked after the key received is inputted
Picture file.
Such as：User A sends the picture to user B, and A selection pictures are shared by short message, can prompt to use when click is shared
Whether family, which needs, is encrypted, and user's selection is to generate key, and then picture becomes ciphertext, then is connect by short message sending to B, B
After being subject to picture, checking can prompt to need to decrypt during file, and the key that A is given inputs, then can be converted in plain text, then B
It can normally check picture.

Make, be exactly by bit exclusive or by round key with (state) in plain text.Round key is obtained by cipher key spreading, just know key with initially it is bright
Wen Jun is that user oneself is set.In simple terms, key add operation is exactly byte-by-byte addition, i.e. exclusive or.
Cipher key spreading is that initial key values are iterated computing according to a kind of algorithm, is obtained required close during often wheel encryption
Key.
AES encryption algorithm is based on arrangement and in-place computation.AES encryption process is related to 4 kinds of operations：Byte replaces
(SubBytes), row displacement (ShiftRows), row obscure (MixColumns) and InvAddRoundKey (AddRoundKey), AES solutions
Close process is the inverse operation of ciphering process, such as Fig. 3.
The inverse operation of each step difference respective operations of decrypting process.
The order of all operations of encryption and decryption is exactly opposite.Formally due to this two promise, decryption can be correctly extensive
Recover lost eyesight text.The key often taken turns in encryption and decryption is obtained respectively by cipher key spreading of meeting accident.The plaintext of 16 bytes, ciphertext and wheel are close in algorithm
Key is all represented with the matrix of one 4 × 4.
AES is an iteration, the password of symmetric key grouping, it can use 128,192 and 256 keys, and
With 128 (16 byte) block encryptions and ciphertext data.With public key cryptography using key to difference, symmetric key cipher makes

It is close, other users are then shared with, after picture is sent to other users, other side is also required to key and carrys out the browsable figure of decryption side
Piece, makes the other users of no key can not check picture, so as to achieve the purpose that maintain secrecy to picture, effectively improves and shares figure
Security during piece；
2nd, individual privacy can more easily be protected, it is ensured that file data is not stolen in transmission process, even if stolen
Other side is taken not have key that can not also check original；In addition, recipient needs secret key decryption that can just inquire about after receiving file, may be used also
It is arbitrarily checked to avoid other people；
3rd, in transmission process, if attacker intercepted and captured send information, it is seen that simply ciphertext, do not take decryption hand
Section can not obtain clear content；Recipient similarly has no idea to obtain after the ciphertext that sender sends is had received
In plain text, key must be sent to recipient by sender by special approach, safer.
