Backpack password time limit:1000msmemory limit:65536kb64-bit integer IO format:%lldJava class Name:MainSubmitstatus pid:29141The Backpack cipher system is a very classic public-key cryptography system, and the cryptography process is as follows: Select an n-length positive integer super-increment sequence a[i] to meet A[1] Select positive integers m>2*a[n],w and M coprime, V is the inverse of W-modulus m, i.e. (v*w)%m=1. B[i]= (W*a[i])%m. In the case of encryption, a binary str

Many people on the internet are asking how to implement Web System URL transfer (form submission) parameter encryption. For example: To do a user account editing, to pass the user's id,url as follows: http://localhost/mysystem/editAccounts.aspx?ID=2 But do not want to let others know that the user ID is 2, malicious users may also change 2 to another user ID. The parameter values passed by encryption can solve the problem. The following is the base class of DEC encryption and decryption that you

When configuring Hibernate, I met the use of Druid to decrypt the database, leaving a text for the next reference. 1. Encryption and decryption is performed in the SSH framework, respectively: Pom.xml (Data encryption) Config.properties (Configure decryption secret key) So how did these two secret keys come into being? First we have to download a Druid-1.0.16.jar package (download address: Druid-1.0.16.jar) Second, type the command JAVA-CP Druid-1.0

Des is a standard data encryption algorithm, the detailed introduction of this algorithm can refer to Wiki and Baidu Encyclopedia: Wiki Encyclopedia Baidu Encyclopedia PHP has an extension to support DES encryption algorithm, is:extension=php_mcrypt.dll Opening this extension in a configuration file cannot be used in a Windows environment You need to copy the Libmcrypt.dll under the PHP folder to the System32 directory of the system, which is phpinfo to see mcrypt that the module can be test

Kangsheng's Authcode function can be said to make a significant contribution to China's PHP industry. Including Kangsheng's own products, and most Chinese companies using PHP use this function for encryption, Authcode is encrypted and decrypted using XOR. 　　The principle is as follows, if: Encryption Clear text: 1010 1001 Secret key: 1110 0011 Redaction: 0100 1010 To get the ciphertext 0100 1010, the need to decrypt and the key is different or u

to iterate through the number of columns, each time a string that takes a number of columns from the plaintext is saved in the Traverse R, where the end subscript of the last column is processed beyond the string length. The column string is then sequentially added to the corresponding positions of the columns in the square grid.The decryption process is a bit more complicated, because the order of the key pairs is scrambled, the order of the scrambled rows needs to be resumed, the previous pha

The official website specifically states that the message does not need to be encrypted. However, on the Callback Server, that is, on the server of

G RID])The basic method is to iterate through the number of columns, each time a string from the clear text is stored in the traversal R, which is required to handle the end of the last column if the subscript exceeds the string length.The column string is then incremented sequentially to the corresponding positions of the columns in the square grid.The decryption process is a bit more complicated due to the disruption of the key pair sequence. The order of the scrambled rows needs to be resume
