Hashing is used in many problems associated with the processing of digital data.Hashing operation includes receiving a data block of a fixed volume, based on uncertain data (possibly very large) length.There are many algorithms are hashed with different length of hash, speed and other parameters.Most of these algorithms is used exclusively for cryptography.But hashing is used in everyday life.So, using the hash is easily confirmed data integrity.For example, a program developer can place it on multiple servers sharing files .But it can be done and the attacker, adding to the program of malicious code.However, the site developer can be published distributed hash file.And so, as the hash file can be anyone, it is easy to be convinced of its authenticity by simply comparing hashes.Today there are many programs to easily access the file hashes.
- file manager Total Commander.
Open the directory with the files to hash in one of the panels file manager Total Commander.To do t
his, select the drive on which the files by pressing one of the buttons disks or by using the drop-down list located above the bar.By sequentially selecting the directory, go to the desired directory.
Select the files which you want to calculate the hash.Use the "Up" and "Down" sums mouse over the list to the desired line.Press the Insert key or Space to highlight the file name.
hashed files.From the main application menu, select "File" and then select "Create a file SFV-checksum (CRC) ...".In the dialog that appears, select "MD5".You can also check the box "for each file to create a separate SFV-file".In this case, the hash value of each file will be placed in a separate file.Click "OK".Wait until the process of calculating hashes.Hash result will be placed in a file or files with the extension ".md5".
Get the hash values.Open the file with the extension ".md5" program to display text files or a text editor.It will contain the hash values, one per line with the following names for these files that was created by a hash.
Hashing files can take a long time if the files are quite large.
