Susa iphasiwedi eyaziwayo kufayela le-PDF ku-Ubuntu

Isebenzisa i-Qpdf

I-Qpdf iyi- Isoftware yokuguqula ifayela le-PDF isetshenziselwe i- ngemfihlo futhi ubethele amafayela e-PDF. Kuyasisiza futhi ukuguqula amafayela e-PDF uwahambise kwamanye amafayela alinganayo e-PDF. I-Qpdf iyatholakala kumakhosombe wokuzenzakalelayo wokusabalalisa okuningi kwe-Gnu / Linux, ukuze ukwazi ukuyifaka usebenzisa umphathi wephakheji ozenzakalelayo. Ku-Debian, Ubuntu ne-Linux Mint singayifaka ngokuthayipha ku-terminal (Ctrl + Alt + T):

sudo apt-get install qpdf

Ngalesi sibonelo nginefayela le-PDF elivikelwe ngephasiwedi elibizwa ngokuthi 'isibonelo.pdf'. Njalo lapho ngiyivula, ifayili licela ukufaka iphasiwedi ukubonisa okuqukethwe kwayo.

Ngiyayazi iphasiwedi yefayela le-pdf. Noma kunjalo, angifuni ukwabelana ngephasiwedi nanoma ngubani. Engizokwenza ngizokwenza nje susa iphasiwedi kufayela le-PDF ngosizo lwe-Qpdf, ngokulandelayo:

qpdf --password='123456' --decrypt ejemplo.pdf salida.pdf
