corresponding key when reinstalling the system, the encrypted file may never open. This is not difficult to understand, because each time the operating system is installed, the operating system will generate a SID number, of course, if the user's character is good enough, still can generate the same Sid number (joking). For backup administrator accounts and passwords, you can use the Forgotten Password Wizard built in Windows2000 and later to help you back up your passwords. I hope we can give

Is there a risk of a leak if the site saves MD5 or other methods of encrypting the password? The original password only the user knows, the website also does not know. And this encryption algorithm plus the site's own password string, so even if the database is compromised, the password is actually useless, neither can be used to log in, nor can be used for multiple sites of the general, even if the user each site used to be the same user name and p

First, the file encryption compression and decompression with the tar commandcompression:tar-zcf-filename |openssl des3-salt-k Password | DD Of=filename.des3This command compresses the filename file to generate a FILENAME.DES3 encrypted compressed file, password the encrypted password.decompression:DD if=filename.des3 |openssl des3-d-k password | Tar zxf-Note that the "-" at the back of the command will release all files, and K password can not, and will prompt for a password when decompressed.I

But shell scripts are readable and writable, and are likely to reveal sensitive information, such as user name, password, path, IP, and so on. Similarly, sensitive information is leaked when the shell script is run. SHC is a tool for encrypting shell scripts. Its role is to convert the shell script into an executable binary file. This is a good solution to the above problems. SHC Installation Yum-y Install SHC If Yum can not be installed, please

(Pubic Key Infrastructure) Asymmetric encryption algorithm, the public key certificate is used for encrypting, and the private key certificate can be opened when decrypting. If the document is compromised, it also represents the user's private key certificate being compromised. In order to facilitate the safekeeping of use, there are also users to the private key certificate into the U-key, the use of the need to insert U-key. Both encry

Click to enter, showing the "Protect Workbook" and "Protect Worksheet" two major options, if you do not want someone to open or modify your workbook, then select "Protect Workbook", enter the password and save, Others will not see the table work thin.

What is SSD? A Solid State Disk (Solid State Disk or Solid State Drive), also known as an electronic hard Disk or Solid State electronic Disk, is a hard Disk consisting of a control unit and a Solid State storage unit (DRAM or FLASH chip. The interface specifications, functions, and usage of SSD are the same as those of common hard disks, and the product shape and size are also the same as those of common h

Can traditional RAID be built on SSD? When asked whether traditional RAID can be built on SSD, the first response should be "yes, but Trim command support is required ". On the Internet, we can also see that many people use SSD to create RAID, but basically it is configured as RAID 0 or RAID 1. Few people will build RAID5. Why? The answer is very simple. If you c

Years later, the use of their spare time and intermittent will caffe SSD source read, although the middle due to work for a period of time, but finally completed successfully, SSD source reading is also this year's annual plan of the more important one of the content, completed or very fulfilling. after reading the code, one of the biggest experience is that before the paper a lot of confused my details now

PCIe SSD introduction and application (I), pciessd introduction and application SSD with SATA/SAS interfaces has been available for more than a decade and has been widely used in the personal consumption field. However, its performance still cannot fully meet the high throughput and low latency requirements of enterprise users, A few years ago, the world's first PCIe interface

Focus on SSDs has been around for some time, the previous few years SSD capacity is small, more importantly, its limited life and expensive prices so that SSD can only be used as a storage area of the accelerated media exist, if anyone who want to use SSD as a disk array, the system is a bit too crazy. As a result, in previous years, both academia and industry ha

OSX: it may not be a good idea to enable the ssd trim function. A long time ago, since people started loading SSD to Mac machines and OSX began to support TRIM, people began to pay attention to enabling the TRIM function of OSX to optimize SSD performance, this is the slowest operation for SSD, especially when there ar

The use case is simple, I want to use both SSD disks and SATA disks within the same machine and ultimately create pools pointing to SSD or SATA disks. in order to achieve our goal, we need to modify the crush map. my example has 2 SATA disks and 2 SSD disks on each host and I have 3 hosts in total.

From: http://yblog.org/archive/index.php/11734 The biggest difference between an SSD and a general traditional hard drive is that its memory-to-life ratio is limited, and the fast Memory (flash memory) in the same data area) SSD memory uses a special algorithm built in the control chip to evenly distribute data to the fast-moving memory chip in different regions. For Ubuntu Linux, my Acer 3750g laptop is Ub

If this backup is lost, a backup of the recovery key can be performed in the Control Panel-the corresponding drive in the system and secure-bitlocker Drive encryption. After you have backed up the key, you can begin encrypting the drive. The process tak
