WinXP techniques for decrypting files by command line

There are many ways to decrypt files, and the WinXP system provides users with a special feature--cipher the file or folder with the command line. Let's take a look at the function below.

Detailed details are as follows:

1. Command format:

cipher [{/e|/d}] [/sir] [/a] [i] [/f] [/q] [/h] [/k] [/u[/n]] [PathName [...]] | [/rathnamewithoutextension] | [/wathname]

2. Parameter setting:

Used without parameters, cipher displays the encryption status of the current folder and the files it contains.

/e encrypts the specified folder. After the folder has been marked, files that are added to the folder later are also encrypted.

/d decrypts the specified folder. After the folder has been marked, files that are added to the folder later are also encrypted.

/s:dir performs the selected operation in the specified folder and all its subfolders.

/A perform file and directory operations.

/I continues to perform the specified operation even if an error occurs.

/F encrypts or decrypts all specified objects. By default, cipher skips encrypted or decrypted files.

/q reports only the most basic information.

/h displays files with hidden or system attributes. By default, these files are not encrypted or decrypted.

/k creates new file encryption for users running cipher. If you use this option, Cipher ignores all other options.

/u updates the user file's encryption key or restores the agent key to the current file in all encrypted files on the local drive (if the key has changed). This option is used only with/N.

/n prevents key updates. Use this option to find all encrypted files on the local drive.

PATHNAME specifies a style, file, or folder.

/rathnamewithoutextension generates a new recovery agent certificate and private key, and then writes them to the file (the name of the file is specified in pathnamewithoutextension).

/wathname deletes data from unused portions on a volume.

/? Display Help at the command prompt.

After learning the command line settings above, friends will know how to add and decrypt files through the command line. May be a bit more parameters, friends may wish to back up to prepare for a rainy.
