Tomb. Tomb is a free and open source tool for easily encrypting and backing up files on GNU/Linux …
EFS works by letting you apply encryption to already-existing files or folders in your file system. You can still edit or modify these files or folders following the encryption process. That zip file will contain the encrypted (and executable if it is a script) version of your file. This allows you to " easily " and " conveniently " encrypt a file/script without having to satisfy any package or module requirement on every system you intend to use the script on or run several complex and confusing incantations of openssl commands. May 31, 2017 · Another encryption option for your consideration is an encrypted archive, which is a secure file that contains other files which you want to protect. The easiest example of this would be an encrypted zip file, but there are better options in my opinion. Contents encryption¶ For file contents, each filesystem block is encrypted independently. Starting from Linux kernel 5.5, encryption of filesystems with block size less than system’s page size is supported. Each block’s IV is set to the logical block number within the file as a little endian number, except that: Hi all, I'm looking for secure file encryption tools that use MAC address as encryption key. FYI, I'm using Red Hat Enterprise Linux OS. For example: when A wants to send file to B A will encrypt the file with B's computer MAC/IP address as an encryption key This file can only be decrypted (2 Replies)
1) need the same key (meaning you could use symmetric or assymetric encryption) 2) use seperate keys with copies of the files encrypted for each user - NB see also Thomas' answer - seems to suggest that GPG supports multiple target encryption, although I'm not familiar with that. 3) use the same key but with three copies using different passphrases

Jun 23, 2015 · Or would they like Linux to take care of the encryption itself at the file system level? In the case of Linux taking care of it, LibreOffice would have to do nothing other than read and write the files as it currently does. Linux would encrypt the file before actually writing it to the disk, and decrypt it after reading it back.
Mar 16, 2018 · Figure 4: Selecting your recipients for encryption. If you receive an encrypted file from a user who has your public key (or you have a file you’ve encrypted yourself), open up Dolphin, navigate to the file in question, double-click the file, give the file a new name, type the encryption passphrase, and click OK. Red Hat Enterprise Linux 6 provides a technology preview of eCryptfs, a "pseudo-file system" which provides data and filename encryption on a per-file basis.The term "pseudo-file system" refers to the fact that eCryptfs does not have an on-disk format; rather, it is a file system layer that resides on top of an actual file system. 1) need the same key (meaning you could use symmetric or assymetric encryption) 2) use seperate keys with copies of the files encrypted for each user - NB see also Thomas' answer - seems to suggest that GPG supports multiple target encryption, although I'm not familiar with that. 3) use the same key but with three copies using different passphrases Aug 21, 2018 · When storing encrypted output to a file you can also omit -a option as you no longer need the output to be ASCII text based: $ echo "OpenSSL" | openssl enc -aes-256-cbc > openssl.dat enter aes-256-cbc encryption password: Verifying - enter aes-256-cbc encryption password: $ file openssl.dat openssl.dat: data Jan 05, 2017 · It is a command line encryption and signing tool to secure files. We can easily encrypt the important and confidential files and documents using GPG and send/receive them over Internet. There are, of course, plethora of methods, applications, tools, and utilities are available to encrypt and decrypt files in Linux.
