FILE DECRYPTION TOOL ARCHIVE

The very famous open source 7-zip archiver written in C++ and able to compress and uncompress most of the known archive file format. $ openssl enc -aes-256-cbc -d -in ~/Desktop/Tecmint/tecmint.dat > ~/Desktop/Tecmint/tecmint1.txt

FILE DECRYPTION TOOL FULL

-out : full path where it will be decrypted.ĭecrypt a file using openssl.

-in : full path of file to be encrypted.

-aes-256-cbc : the algorithm to be used.

$ openssl enc -aes-256-cbc -in ~/Desktop/Tecmint/tecmint.txt -out ~/Desktop/Tecmint/tecmint.datĮxplanation of each option used in the above command. $ sudo apt-get install opensslĮncrypt a file using openssl encryption. You may like to install openssl, if it is not already installed. Openssl is a command line cryptographic toolkit which can be used to encrypt message as well as files. You need to provide the same password you provided at encryption. A archive is created with the name tecmint.zip with zipped files tecmint.txt, tecmint1.txt and tecmint2.txt.ĭecrypt the password protected zipped file using unzip. Here mypassword is the password used to encrypt it. $ zip -password mypassword tecmint.zip tecmint.txt tecmint1.1txt tecmint2.txt $ sudo apt-get install zipĬreate a encrypted zip file (several files grouped together) using zip.

$ bcrypt ~/Desktop/Tecmint/tecmint.txtĪs soon as you fire the above command, a new file name is created and original file tecmint.txt gets replaced.ĭecrypt the file using bcrypt. $ sudo apt-get install bcryptĮncrypt the file using bcrypt. If you have not installed bcrypt, you may apt or yum the required package.

Note: Enter Paraphrase twice to encrypt the given file. You may list the content of the directory to verify. As soon as you run the gpc command with option -c (encryption only with symmetric cipher) it will create a file. We have a text file ( tecmint.txt) located at ~/Desktop/Tecmint/, which will be used in the examples that follows this article.īefore moving further, check the content of the text file. In most of the today’s Linux distributions, the gnupg package comes by default, if in-case it’s not installed you may apt or yum it from repository.
