5.3 Compression and Encryption

Standard ZIP compression is used to generate the ‘RTA’ files. As these files may be sent/received by e-mail, they are always encrypted so that any Antivirus/Antispam system can modify its contents. The unique ‘arte’ password is used to encrypt the files.

• Manually creating/modifying an RTA file

  To create an ‘RTAv2’ file with the files test.conf, test.tcl, version, description.xml, foo.txt and foo2.txt, the following command may be used:

  $> zip -e test1.rta test.conf \ test.tcl \ version \ description.xml \ foo.txt \ foo2.txt

  ... and type ‘arte’ when it requests a password.

  To extract any ‘RTA’ file manually, you may use:

  $> unzip -P arte test1.rta

• Using the suite sandbox to create/modify an RTA file

  You may also use the -x and -k arguments of the arte command to work with the contents of an existing RTA in the suite sandbox (see Execution arguments).

• Using the arte_rta.sh helper

  The ARTE distribution also provides a helper script to work with multiple RTA files, named arte_rta.sh. You can run this script in the directory where the RTA files for a given suite are stored:

  Run the following to decompress al RTA files and create .rta.dir directories:

  $> ./arte_rta.sh unzip

  Run the following to compress the .rta.dir directories again back into correct RTA files:

  $> ./arte_rta.sh zip
