Disable Trash / KGPG Default Setting / Context Menu

[Rog131]

Re: Disable Trash / KGPG Default Setting / Context Menu

Hmm - myencryptfolder.desktop is alpha ( )version. It is works only with small folders. If there is larger folder, gpg starts before ark (zip) is finished.

myencryptfolder.desktop (versio 0.00002) :

[Desktop Entry]
ServiceTypes=inode/directory
Actions=MYencrypt

[Desktop Action MYencrypt]
Name=Archive & Encrypt Folder (GPG)
Icon=gpg
Exec=myfolderencrypter %U

myfolderencrypter script:

#!/bin/sh

# killing ark prosesses
kill `ps -e | awk '/ark/ { print $1 }'`

# packing folder
ark --add-to $1 $1.zip

# waiting ark to shut down
while [ `ps -e | grep ark | wc -l` -gt 0 ]
do
  sleep 1
done

# encrypting zip package
gpg -c $1.zip

# removing zip package
rm -f $1.zip

Note
- Make script file
- Make it executable.
- Drop it in the /usr/bin/
- It is clumsy way (first in the mind) to do this


Example, decrypting and extracting

mydecrypt.desktop:

[Desktop Entry]
ServiceTypes=all/allfiles
ExcludeServiceTypes=kdedevice/*
Actions=MYdecrypt

[Desktop Action MYdecrypt]
Name=Decrypt & Unzip (GPG)
Icon=gpg
Exec=decrypter %U

decrypter script:

#!/bin/sh

# Where is the new subfolder
WHERE=`kdialog --getexistingdirectory ~/`

# removing .gpg extension
PACKAGE=`echo $1 | sed s/".gpg"//g`

# decrypting package
gpg -d $1 > $PACKAGE

# unpacking to the new subfolder
unzip $PACKAGE -d $WHERE

Note #1
This service menu, script-file pair will ask where to decrypt/unpack. It is using KDE dialogs:

Note #2
These seem to work . Testing needed !

Re: Disable Trash / KGPG Default Setting / Context Menu



Cool, that works pretty good!

It has only a problem with spaces in the file/folder name (please see attachment). I guess the name is cut somehow, but I don't understand why. "ark --add-to $1 $1.zip" from where does $1 come? I guess there is the mistake..?

I added this to my /usr/share/apps/d3lphin/servicemenus/ folder
myencryptfile.desktop

[Desktop Entry]
ServiceTypes=all/allfiles
Actions=MYencrypt

[Desktop Action MYencrypt]
Name=Archive & Encrypt File (GPG)
Icon=gpg
Exec=myfolderencrypter %U

I guess the same argument for big folders are true for big files.

Is it possible to show the "decrypt"-servicemenu entry only by an GPG extension? Right now it will shown by every extension.

Those scripts should be standard in KDE at least in Kubuntu. I think this would encourage more ppl to use encryption. I will make a proposal (when I found the place to do this ).

Great work Rog131!!

"ark --add-to $1 $1.zip" from where does $1 come?

$1 (and $2, $3...) =>

but i can't find what is working with gpg's (tried encrypted/gpg, application/gpg...)

Where that error came ?

[squirrel]

Re: Disable Trash / KGPG Default Setting / Context Menu

The error comes straight after you try to use the "archive & encrypt" service with a file or folder name which contains a space...

Is it because "kill `ps -e | awk '/ark/ { print $1 }'`" prints no spaces (that's a general problem with Linux, right?)?

Yes and no .

That line is for killing ark prosesses. It is working. The problem is:
Example - trying to pack and encrypt folder A 012:

myfolderencrypter /media/sda6/tmp/A 012

-> myfolderencrypter is trying to process folder /media/sda6/tmp/A

fix:

myfolderencrypter "/media/sda6/tmp/A 012"

Same thing with "$1" and "$U"

So:
myencryptfile.desktop needs:

Exec=myfolderencrypter "%U"

and in the myfolderencrypter:

ark --add-to "$1" "$1.zip"

while I have quotes in my example, they are not always necessary. where you need quotes is when your variable names include spaces. For example,

X=hello world # error
X="hello world" # OK

Re: Disable Trash / KGPG Default Setting / Context Menu



Now the compressing part works, but not the encrypting part. I'll have a look later into this, I'm short in time right now.

Update
====
Got it:

You have to add this to the "myfolderencrypter" located in "/usr/bin"

# encrypting zip package
gpg -c "$1.zip"

# removing zip package
rm -f "$1.zip"

The only thing that is missing is to show the decrypt menu entry only to encrypted files and the encrypt entry only to files who are actually not encrypted. I'll try to figure that out later.

Thanks Rog131! You helped me here a lot and I really appreciate that. Kubuntu is indeed way better than Ubuntu

Re: Disable Trash / KGPG Default Setting / Context Menu

I've updated the scripts from Rog131 a little bit.

/usr/bin/decrypter

#!/bin/sh

# Where is the new subfolder
WHERE=`kdialog --getexistingdirectory ~/`

# removing .gpg extension
PACKAGE=`echo $1 | sed s/".gpg"//g`

# decrypting package
gpg -d "$1" > "$PACKAGE"

# unpacking to the new subfolder
unzip "$PACKAGE" -d "$WHERE"

while [ `ps -e | grep unzip | wc -l` -gt 0 ]
do
  sleep 1
done

# removing zip package
rm -f "$PACKAGE"

/usr/bin/myfolderencrypter

#!/bin/sh

# killing ark prosesses
kill `ps -e | awk '/ark/ { print $1 }'`

# packing folder
ark --add-to "$1" "$1.zip"

# waiting ark to shut down
while [ `ps -e | grep ark | wc -l` -gt 0 ]
do
  sleep 1
done

# encrypting zip package
gpg -c "$1.zip"

# removing zip package
rm -f "$1.zip"

Open Issues
------------------
* I wasn't able to find a solution to show the encrypt/decrypt servicemenu entry only to uncrypted/encrypted files. There is the "application/x-kgpg" as a MIME-type, but that does somehow not work
* I would like to have a check if the file/folder already exists while decrypting/encrypting

[Rog131]

Re: Disable Trash / KGPG Default Setting / Context Menu

Here is example with a check if the file/folder exists.

Encrypting:




Decrypting:




cryptic.desktop:

[Desktop Entry]
ServiceTypes=all/allfiles,inode/directory
Actions=Encrypt;Decrypt;
Encoding=UTF-8
X-KDE-Submenu=Encrypt and Decrypt

[Desktop Action Encrypt]
Type=Application
Name=Pack and Encrypt (GPG)
Icon=forward
Exec=encrypter "%U"

[Desktop Action Decrypt]
Type=Application
Name=Decrypt and Unpack (GPG)
Icon=back
Exec=decrypter "%U"

Note #1
You need to edit edcrypter and decrypter scripts. There is:

# temporary workdirectory
WORKDIR="/home/YOURNAMEHERE/temp"

Note #2
It seems to work


encrypter and decrypter scripts:

Re: Disable Trash / KGPG Default Setting / Context Menu

Hi Rog131

Thank you for this! I just changed the temporary directory to "/tmp/".

Right now I've not enough time to look into this, but it seems to me the decrypt function does not work. None of the options are working and the question is always coming up, even if there is no file/folder with the same name.

I'll test it further tomorrow and maybe I'll find even the bug...

[Rog131]

Re: Disable Trash / KGPG Default Setting / Context Menu

Thank you for this! I just changed the temporary directory to "/tmp/".

You can use /tmp but not /tmp/ !. Scripts are making temporary folders: /path/something#. # is timestamp (date +%s -> now it is 1202066658)

DATE(1) User Commands DATE(1)

NAME
date - print or set the system date and time

SYNOPSIS
date [OPTION]... [+FORMAT]
date [-u|--utc|--universal] [MMDDhhmm[[CC]YY][.ss]]

DESCRIPTION
Display the current time in the given FORMAT, or set the system date.

%s seconds since 1970-01-01 00:00:00 UTC

Note
Scripts last step is to REMOVE tempory folder !

[squirrel]

Re: Disable Trash / KGPG Default Setting / Context Menu

Ok. I changed it to "/home/user/temp"

Now the decryption works almost perfectly. I've two issues so far. One is the overwriting does not work properly and I get an old timestamp (2005-09-10 04:25) by the unpacked files and even if I create new files...

Gotta go now. Sorry.
