Intai voi crea un director

[root@testpup ~]# mkdir director_de_test
[root@testpup ~]# file director_de_test/
director_de_test/: directory

Apoi il voi cripta:
[root@testpup ~]# openssl aes-256-cbc -salt -in director_de_test/ -out director_de_test_criptat
enter aes-256-cbc encryption password:
Verifying – enter aes-256-cbc encryption password:
3078342380:error:0200B015:system library:fread:Is a directory:bss_file.c:245:
3078342380:error:20082002:BIO routines:FILE_READ:system lib:bss_file.c:246:
[root@testpup ~]# file director_de_test
[root@testpup ~]# file director_de_test_criptat
director_de_test_criptat: data

Se observa ca sistemul vede directorul director_de_test_criptat ca fiind de tip:data(cryptat)

Acelasi lucru putem sa il facem si pentru un fisier,de exemplu aici am folosit un fisier text.

[root@testpup ~]# touch fisier_de_cryptat
[root@testpup ~]# file fisier_de_cryptat
fisier_de_cryptat: empty
[root@testpup ~]# vim fisier_de_cryptat
[root@testpup ~]# file fisier_de_cryptat
fisier_de_cryptat: ASCII text
[root@testpup ~]# openssl aes-256-cbc -salt -in fisier_de_cryptat -out fisier_cryptat
enter aes-256-cbc encryption password:
Verifying – enter aes-256-cbc encryption password:
[root@testpup ~]# file fisier_
fisier_cryptat fisier_de_cryptat
[root@testpup ~]# file fisier_cryptat
fisier_cryptat: data
[root@testpup ~]# cat fisier_cryptat
Salted__▒▒ ▒▒▒▒▒▒qPeZ▒yl[▒▒▒S▒묚M▒▒#i?▒+fC▒[root@testpup ~]#

Aici se vede mult mai bine cum arata textul criptat(in fisierul txt original era introdus textul “Test de criptare”)
