Kulo Inqaku langaphambili besikuxelele ngeCryptmount oko ikukuthi Isixhobo Sinayo kwiLinux Isinika ithuba lokwenza iinkqubo zokubethela ifayile, eluncedo kakhulu xa ufuna ukukhusela ulwazi lwethu kubantu abangagunyaziswanga.
Kulungile ke kweli nqaku litsha Siza kubona ukubanakho kokubamba iifayile kumfanekiso ofihliweyo Ngoncedo lwezi zinto ziluncedo, koku siza kusebenzisa izixhobo ezongezelelweyo esele sinazo ngaphakathi kweLinux.
Inyathelo lokuqala into esiza kuyenza yile yenza ikhonteyina yethu apho iifayile eziza kubethelwa ziya kugcinelwa oku siza kusebenzisa isixhobo se-dd esiya kusixhasa ukwenza umfanekiso ongenanto apho singabamba khona iifayile zethu kwaye sizikhusele kuyo.
Kule nto siza kwenza ifayile ngokobungakanani bolwazi oluza kubanjwa nangona singakunika indawo ethe kratya yohlelo oluzayo, oku kukwimfuno zakho, singathatha i-100 MB njengesiseko somzekelo nje.
Ngale nto siza kuvula i-terminal kwaye siza kwenza lo myalelo ulandelayo:
dd if = /dev/zero of = el-nombre-que-tu-quieras.img bs = 1M count = 100
Kusetyenziswe i-cryptmount ukubethela iifayile
Ukuba isixhobo sifakwe kwikhompyuter yethu, vSiza kuhlelela itemplate ekule ndlela ilandelayo:
/ njl / cryptmount / cmtab
Kubalulekile ukukhumbula oko Ushicilelo loku kufuneka lwenziwe ngemvume ephezulu yomsebenzisi. Banokukwenza kunye nomhleli abazikhethele bona. Kule fayile siya kufumana oku kulandelayo kwaye sinokuyihlela:
TARGET_NAME {
dev=DEVICE
flags=FLAG,FLAG,...
startsector=STARTSECTOR
numsectors=NUMSECTORS
loop=LOOPDEV
dir=MOUNT_POINT
fstype=TYPE
fsoptions=OPT,OPT,...
cipher=CIPHER
ivoffset=IVOFFSET
keyformat=KEYFORMAT
keyfile=KEYFILE
keyhash=KEYHASH
keycipher=KEYCIPHER
keymaxlen=KEYMAXLEN
passwdretries=NUMATTEMPTS
}
Kwaye isekwe koku kulandelayo kwaye Ukuba ukhetha, unokukopa kwaye uncamathisele, hlela kuphela iindlela:
# /etc/cryptmount/cmtab
# example file - please modify before use
contenedor {
dev=/ruta/a/la/imagen/creada
fstype=ext4
mountoptions=defaults
cipher=aes # filesystem encryption
keyfile=/ruta/a/la/clave/de/tu/imagen.key
keyformat=builtin
}
Ungalitshintsha igama "lesikhongozeli" kuyo nayiphi na into oyifunayo, ungongeza ezinye iiparameter, ukuba ufuna ukwazi ngakumbi ngazo ndikushiya eweikhonkco elilandelayo.
Ngoku Siza kuqhubeka nokumisela isikhongozeli seefayile zethu, inyathelo lokuqala kukwenza igama eligqithisiweyo encryption ekufuneka ihambelane ngokupheleleyo nenkqubo yokubethela ukuba sikhetha, oku kuthintela iimpazamo ezinokubakho.
Ngale nto siza kusebenzisa isitshixo sokubhala ngokufihlakeleyo, sivula i-terminal kwaye siphumeze:
sudo cryptmount --generate-key 32 contenedor
Xa usenza lo myalelo, kwangoko Siya kucelwa ukuba siseke iphasiwedi ekufuneka siyikhumbule okanye ugcine kwindawo ekhuselekileyo ngokupheleleyo.
Uyenzile ngoku Siza kwenza lo myalelo ulandelayo ukulungiselela isikhongozeli sethu:
sudo cryptmount --prepare contenedor
Oku kudala ifayile yefayile, '/ dev / mapper / container', esivumela ukuba senze inkqubo yefayile.
Ngoku siza kuqhubeka nokwenza inkqubo ngeemate2fs:
sudo mke2fs /dev/mapper/contenedor
Kwaye senza:
sudo cryptmount --release contenedor
Ungazibamba njani iifayile kumfanekiso ofihliweyo?
Ukuze uqalise ukusingatha iifayile esifuna ukuzikhusela kumfanekiso ofihliweyo, Kuqala kufuneka senze indlela apho iyakonyuswa khona kwaye yehlisiwe kwaye iyakuba yindlela esinokuthi sisebenze kuyo.
Unokwenza ifolda kwindlela oyikhethayo, umzekelo kwifolda yakho, kwenye i-hard drive, njl.
Umzekelo, ngoncedo lwesiphelo unokwenza lo myalelo ulandelayo:
mkdir carpetaprueba
Kwaye incwadi eneenkcukacha ebizwa ngokuba yifolda yovavanyo iya kwenziwa ngaphakathi kulawulo lwasekhaya.
Ukuba bafuna ukwenza incwadi eneenkcukacha ngaphakathi kwifolda zenkqubo baya kufuna ingcambu kunye ngoku senza lo myalelo ulandelayo:
cryptmount -m contenedor
Y ngoku sinokuhambisa ubunini bomsebenzisi ngalo myalelo ulandelayo:
sudo chown tunombredeusuario /tu/ruta/a/la/carpetaprueba
Ngale nto siya kuba nomfanekiso onyusiweyo ukuqala ukwenza ukuhanjiswa kweefayile kuye, ngokungathi yenye ifolda apho sinokutshintsha khona, senze okanye sicime iifayile eziqulathwe apho.
Ekugqibeleni, ekupheleni komsebenzi kunye nomfanekiso siyaqhubeka nokuwuqhawula kunye nomyalelo olandelayo:
cryptmount -u contenedor
