Ubuntu Security :: Small Portable Encrypt/decrypt Programme ?
Mar 31, 2011
I was wondering if any free, small, portable, cross platform programme exists for encrypting/decrpyitng simple txt files?
I know a couple of small ones for windows systems (nosee, dscrypt) but i wonder if there is any i could use on both linux and windows OS. the idea is to be able to carry it on USB key and the programme (or probably there will have to be 2 versions of it) would run either on windows or linux os and i could decrypt and encrypt the file if i needed to. no matter on what system i plug the USB key to.
I'm trying to setup vi to automatically encrypt/decrypt .pgp and .asc files. The encryption part works. If I "vi testfile.gpg" it will auto encrypt it on save.
However when I try and vi the encrypted file it does not prompt me for my pass phrase. I just get this:

Here's what I have in my ~/.vimrc file.

This is on gentoo linux if it makes any difference.
I want to be able to encrypt files on my netbook with Ubuntu 9.04 UNR and on my MacBook (Mac OS 10.6.2) and be able to exchange them and decrypt them on the other platform.The Ubuntu command Edit>Encrypt is so easy to use but works only on the netbook. I haven't, thus far, found a program to open them on the Mac or to create an encrypted file on the Mac that I can open on the netbook.
I need to be able to decrypt data, like simple text files, that have been encrypted and base64 encoded with my public key.I need to use openssl so i do:
and i get exactly the same data as before the command was run. Am i right in thinking that i need to decode before decrypting? I tried decrypting, before i realized that i had to decode first,using this command:
lets say I install Ubuntu 10.10 on my laptop. I check the box that says encrypt my home directory, and my password is a randomly generated 10 character password using uppercase and lowercase letters and numbers. The next day my laptop gets stolen or something. How hard would it be for someone to decrypt the home directory if that were the goal?
Is there a way for my home folder to not be automatically mounted when i log in? And for that matter a way to change the password from my log in password to something else?
1. I understand you can protect your files or directories in your website by setting file/directory permissions. The meaning of r w x is clear to me, but I'm not sure how to proceed... Starting with the index.html file, if I wanted to make it so that anyone in the world can read it but can't modify it, do I set its permissions to rwxr-xr-x? If I set it to rwxr--r--, would that mean the file couldn't be served? I mean, what does the x setting do on a .html file, how can a .html file be executable?
2. If file permissions work on the lines of owner-group-others, in the context of a website, who is 'group'? As far as I can tell, there's only the owner, which is me, and others, which is the world accessing the site. Am I correct in thinking that by default, say when creating a website on a shared hosting server, there is no group unless I specifically set one up?
3. My ISP allows the DynDNS.org service, meaning that I could serve a website from my home. It's too early to go that route just yet, but for future reference, I would like to ask about the server software called Hiawatha. It is said to be secure, but having read some evaluations of it, it doesn't seem to offer anything that couldn't be accomplished with Apache or Cherokee, it's just that its security settings are simpler and easier to configure. Am I right about this? Or does Hiawatha truly offer something that the other major server packages don't?
Does "Portable Ubuntu" run separate from Windows? Point being, would I be vulnerable to Windows based trojans if I ran Firefox from Portable Ubuntu on Windows?
I'm currently writing a simple script which uses luckyBackup to backup my /home directory to /tmp. I then want to tar it, encrypt it with gpg and move it onto a usb stick. My question is that suppose my hard disk died and I needed to restore from this USB backup, would I still be able to decrypt the file given that I would have lost gpg keys etc when the disk died? (I would still know the passphrase though). Should I be backing up gpg files separately?
I have a ext hdd..seagate go. And my 14 yr old son likes to get into it without asking me; of course i dont care when he asks but i don't really want him to get in there and erase anything. I am about to leave for training for 18 weeks with the military. Is there a way i can "secure" the drive for the amount of time that I can't take it with me?
I loaded Ubuntu desktop onto my flash drive with the USB Installer For Ubuntu from [url]
I'll be placing sensitive data on the drive & need to figure out how to encrypt it. From what i've read so far, the easiest way will be to encrypt the swap, /home, tmp, temp files. Not quite sure how to do this. I'd prefer to encrypt the whole drive, but this seems quite complicated.
I already have Ubuntu 9.10 on my system and don't want to have to reinstall all my programs after a clean install. I want to encrypt my hard drive so it will boot and ask for a password. Does anyone know if this is possible?
I'm using lucid desktop edition, and I need to encrypt my home folder, but I didn't mark that option in the fresh instalation of lucid. I'd like the login screen to ask for the password and then decrypt my files.Is it possible to do without erasing my user?
I'm looking for software to encrypt my entire S.O. It's something like nobody can erase the hard drive or can't trying to hack. I'm using Ubuntu Server x64.
I know Pidgin store chat log in plain text or HTML format.Is there any plugin for pidgin to encrypt the chat log while logging it?Similar to Windows version of MSN Messenger free application called MSNPlus! that contains this feature to encrypt chat log.
I just found a neat way to encrypt a file in Ubuntu 10.04.
I right click on a file and select the Encrypt option. The program prompts me to "Choose Recipient" so I choose myself on the list. Then it prompts me to enter my passphrase.
Once all that's done I hit enter and it adds .pgp to the end of whatever file just encrypted. The same basic method is used to Sign the file.
Does it sound as though what I said is correct and that the file I wanted to encrypt was indeed encrypted?
Can anyone crack my files without the passphrase? I'm sure it depends on the complexity and length of the passphrase.
We have some script files on our linux servers. For security purpose our requirement is to keep these files encrypted . I mean when we open the files it will looks like as for example i am showing you one encripted file of iur server. how can i do this.
I have just installed Ubuntu Jaunty (I do not like Karmic, please don't try to make me upgrade) and after installing all my programs I realized I did not encrypt my home directory.
I know it's very simple to do this during the installation but I can't seem to find an option to do it after it.
I recently installed Ubuntu Linux and did not encrypt the home directory during the install. Now I want to encrypt my home directory, or even better the whole hard drive.
Folks:What can I use to encrypt all data on my USB flash drive? If possible, could I use something that has a public Key, so I do not have to type in a password to access the information when I plug the drive into my machie, but will not open or display contant if the drive is plugged into anyone else's machine, unless they have the public key?
I recently upgraded to Ubuntu 10.04. I love the passwords and keys application, but was somewhat surprised at the lack of a context menu in gnome to encrypt a file.
In general, I cannot find how to encrypt files using the keys I generate. Maybe I'm missing something? Probably, I just thought since Ubuntu comes with OOB key generation it would have OOB encryption capabilities.
I've read about seahorse and other ways to ADD encryption, I'm just wondering if ubuntu does it natively. It'd be a good idea to add to brainstorms, right click and encrypt.
So what I want to do is encrypt my entire hard drive, but heres the thing.
I dual boot Ubuntu and windows 7, but I am afraid that if I use truecrypt to do the encrypting that it will wipe GRUB and not allow me to boot into any OS, is that a possibility and is there a way around it?
How would You encrypt Passwords [emails,forums,accounts] onto USB Flash the most Secure way? (It should be command line so I can use any Linux distribution on it.) Is gpg -c <filename> secure enough ? And what FAST distro would you install on it? I'm learning on old USB flash and found SliTaz pretty damn cool,I use it as a LiveUSB. Also I've tried Kubuntu but it's bit slow. Going to try Lubuntu soon too. Any other idea?
And I'd like to install some FAST distro onto new 8GB mini USB flash drive,maybe Kubuntu as well. How would you partition its Flash drive? Probably separate partition for stored encrypted files?
