File encryption download for centos

To check the status of a mirror, please visit mirror-status. The CentOS project hosts our sources at git. This is documented in greater detail in the CentOS wiki. In order to help ease the workload for our primary mirror network, the source rpms are not kept in the same tree as the binary packages.

If you need the source packages used to build CentOS, you can find them in our vault vault. Legacy versions of CentOS are no longer supported. For historical purposes, CentOS keeps an archive of older versions. The software, which encrypts files with either a passphrase or a key, can be used for the encryption and decryption of data, and also functions as a file manager. Tomb is a simple, user-friendly Command Line encryption tool popular among Linux user-developers.

These tombs can be safely transported and hidden in a filesystem, and can be separated for additional security. For instance, your tomb file can be kept on your hard disk and the key files in a USB stick.

Unfortunately, Tomb does not have a graphical user interface GUI and relies on Command Line input in order to function. Learn how to create tombs and how to hide a tomb key in an image in this Tecmint tutorial. CryFS is an excellent cloud-based tool that lets you encrypt your files and store them anywhere. It is compatible with popular cloud services like Dropbox, iCloud and OneDrive, among many others.

The tool goes way beyond just encrypting your files- it also encrypts your file sizes, metadata and directory structure. The base directory contains a configuration file that is encrypted twice - once with aesgcm and once with a password that you choose. This password is also used to conduct integrity checks. Learn how to use CryFS in this tutorial.

The official name of 7-zip for Linux is p7zip. The "p" here is short for POSIX an open standard designed to make applications compatible across different platforms , to indicate that p7zip is a POSIX compliant implementation of 7-zip.

You can download the latest version of 7-zip, 7-zip Learn how to encrypt files on Linux using 7-zip in this TechRepublic tutorial. Tails is a specialized secure Linux distro created for a privacy-oriented user experience.

With a simple mount and unmount command, plus the configuration of bind-hooks , your home can change in a snap to include your secrets in the right position for your application paths, like that secret door behind the library you always dreamed of.

When transporting delicate information the risk of interception is high: even using encryption, if the courier is captured then the key can be found on him or her and the password can be obtained using torture. The solution we propose is that of separating keys from storage, so that a courier alone cannot be the single point of failure.

Never keep your keys where your tomb is! Steganography helps here. Tomb offers the possibility to bury and exhume keys from jpeg images: if steghide is installed on a system then Tomb will offer this commands in its command-line help.

This feature lets you keep in mind a certain picture rather than a position in a filesystem, much easy to remember. It also helps in hiding well the key and eventually communicating it without being suspicious, as it is very difficult to detect the presence of a key inside an image without knowing the password you used to seal it.

Another possibility to keep track of keys is to backup them in a physical form: for that we have the command engrave which will make a QRCode out of a key which can then be printed, but still must be kept secret, like between the pages of your favourite book or so. To recover an engraved key one can simply scan it with any QR decoder mobile application, save the resulting plain text file and use it as a key in Tomb.

Security can be improved by eliminating the single point of failure, especially if a network connection is available. A tomb can be stored and used on a machine while its keys are far away: they get copied and immediately deleted every time, but never stored on the same machine.

Ssh is used for the key transport, which can happen also without passwords by using ssh public keys. A neat setup is that of keeping the tomb on your laptop and the key on your mobile phone, being fairly sure that they are never kept in the same place, pocket or bag. A simple script to make that happen follows, substitute the ESSID with that of your device:. Keeping tombs on remote server shells can be a good deterrent to avoid physical break-ins when travelling, not having to carry anything related to your data.

To a certain degree, using Tomb also makes it difficult to steal the data from servers, even for providers that have physical access to them. For server based usage one has to take care of some things: creating a tomb key is usually very slow on a remote server or VPS, the best is to create the key forge locally on your desktop and then upload it.

Last but not least, it is also possible to mount tombs locally in a way that the remote server will never have anything to do with the clear data contained into them. This is achieved using sshfs :. You may list the content of the directory to verify.

Note : Enter Paraphrase twice to encrypt the given file. The above encryption was done with CAST5 encryption algorithm automatically. You may specify a different algorithm optionally. Now, if you want to decrypt the above encrypted file, you may use the following command, but before we start decrypting we will first remove the original file i.

Note : You need to provide the same password you gave at encryption to decrypt when prompted. Blowfish cipher is not recommended since the time it was figured that the cipher algorithm can be attacked. If you have not installed bcrypt , you may apt or yum the required package.

As soon as you fire the above command, a new file name texmint. Designed as a replacement of UNIX crypt, ccrypt is an utility for files and streams encryption and decryption. It uses Rijndael cypher. Encrypt a file using ccrypt.

It uses ccencrypt to encrypt and ccdecrypt to decrypt. It is important to notice that at encryption, the original file tecmint. You may like to use ls command to check this. It is one of the most famous archive format and it is so much famous that we generally call archive files as zip files in day-to-day communication.

It uses pkzip stream cipher algorithm.
