Moshou ====================================== Method 1 ======================== ============ When someone double-click an MP3 file (or JPG file) with the mouse, it will automatically call software such as Winamp to play the song (or call the Image Browsing software to open the picture). Everything looks normal, no one will think of your confidential files in it. If you want to see the secret, you can change *. MP3 (or *. JPG) to *. rarfile, and click

By compressing files and setting passwords, it is still possible to crack them by running software. Therefore, we have introduced 6 free file encryption tools, encryption of confidential files is a common practice to protect confidential data. The most common method is to compress files and set a set of unzipping passwords, only those who know the password of the restricted file have the permission to read

the opposite.The confidentiality of DES only depends on the confidentiality of the key, and the algorithm is public. The complex structure of DES is the root cause why there is no way to crack shortcuts. DES can now be implemented by software and hardware. ATT first uses an LSI chip to implement all DES working modes. This product is called DEP, a Data Encryption processor.　3. public key cryptography　The public key password system emerged in 1976. Its primary feature is that different keys are

. ● Do not write the server code when hiding a control with a button. You can use JavaScript and dom on the client. For example, if you want to operate the database, it is obviously not possible on the browser side. At this time, you need to write the server code. Operations such as checking the user name and password can be put on the browser side (the user name and password are written to death), technically, but the security is too poor, so they must be put on the server side. 9.4 Principle 3

services or we can use "exception notifier" plugin. 6. Ensure adding entries for cron/scheduled jobs Most of the applications have some Functionality/jobs that need to be run periodically, for example generating invoices, sending newsletters etc. in most cases these jobs are done by a rake task. we shoshould make sure that we have added such jobs to cron or similar program. 7. Monitoring important processes To ensure that our site is up 24 × 7 we need to ensure that all processes that our appli

How to Ensure database security by defining views and access control? Use the SQL language as an example. The view can provide security protection for

Common encryption methods in the project base64, AES, MD5, sha-1, base64sha-1Today, I reorganized several encryption methods that were frequently used in previous projects, we found that we didn't really understand these encryption methods in the past. First of all, from the nature of encryption, it is to output some data with an indefinite length according to certain encoding rules as a data string of a certain length. This is what I understand. Different encryption methods adopt different enco

/identity. pub The user's default RSA1 authentication Public Key (SSH-1 ). This file does not need to be kept confidential. The content of this file should be added to the ~ Of All RSA1 target hosts ~ /. Ssh/authorized_keys file. ~ /. Ssh/id_dsa The user's default DSA Identity Authentication private key (SSH-2 ). The permission for this file should be limited to at least "600 ". When generating a key, you can specify a secret to encrypt the private ke

scaled, in addition, do not use negative margin to prevent style deformation; Do not put confidential information in the Code. As we all know, Silverlight is a client technology. When users are using it, they will download the xap file to their local computer, which is very easy to decompile. Therefore, do not put sensitive confidential data in the Code; Do not use image as the button control; there
