ImpraStorage provided a private imap access to store large files.
Each file stored on the server is split in severals random parts.
Each part also contains random noise data (lenght depends on a crypt key)
to ensure privacy and exclude easy merge without the corresponding key.
An index of files stored is encrypt (with the symmetric-key algorithm
Kirmah) and regularly updated. Once decrypt, it permit to perform search
on the server and download each part.
transfert process is transparent. Just vizualize locally the index of
stored files and simply select files to download or upload.
ImpraStorage automatically launch the parts to download, then merge parts
in the appropriate way to rebuild the original file. Inversely, a file
to upload is split (in several parts with addition of noise data), and
ImpraStorage randomly upload each parts then update the index.

conf command Examples:
Initialize program and set config on default profile with keys generation :
imprastorage conf -K -H imap.gmail.com -P 993 -U login -X password
Set config on a new profile with same keys from previous active profile:
imprastorage conf -H myimapserver.net -P 993 -U login -X password -B boxname -A profile1
Load config from a profile (wich become active) :
imprastorage conf -DA profile2
List config from profile :
imprastorage conf -LA profile1
data command Examples:
List index
imprastorage data -l
Add file
imprastorage data -a /path/tofile 'my video'
Add file with category (category is also a directory structure recreate
when downloading files)
imprastorage data -a /path/tofile '2009 - en la playa' -c videos/perso/2009
Get file by id
imprastorage data -g 22
Remove from server a file by id
imprastorage data -g 22
Search files matching pattern :
imprastorage data -s 'holydays'
Search files upload by a particular user on a category :
imprastorage data -s * -c films -u myfriend
