If you have wget, type the following command (replace 0.1/OT-ISAS/VELLO with your proposal):

Decrypt the data

The data are encrypted with GPG (Gnu/PGP; version 1.0.7). To decrypt the data you need to have installed either PGP or GPG software. We recommend you to use the latest version of GPG or PGP ( how to obtain PGP or GPG).

You can just type

> gpg AKARI_FIS_3160042_001.tar.gpg
and you will be asked your PGP-key. Or you can type as follows.
> echo $key | gpg --cipher-algo=3des --passphrase-fd 0 AKARI_FIS_3160042_001.tar.gpg
Please ignore the following message:
gpg: WARNING: message was not integrity protected

If you want to decrypt several files under a directory, you may use our script, gpgp.sh. 'gpgp.sh -h' gives you some instruction. If you want to decrypt all data under a directory, you can just type as follows.

> gpgp.sh -s gpg 'directory-name'
