GnuPG Kurulumu<\/h4>\n

GnuPG, \u00e7o\u011fu i\u015fletim sisteminde kolayca kurulabilir.<\/p>\n

* Linux (Debian\/Ubuntu tabanl\u0131):<\/strong><\/p>\n

sudo apt update\n    sudo apt install gnupg<\/code><\/pre>\n
*   Linux (Fedora\/CentOS tabanl\u0131):<\/strong><\/p>\n
sudo dnf install gnupg<\/code><\/pre>\n
*   macOS:<\/strong><\/p>\n
brew install gnupg<\/code><\/pre>\n
*   Windows:<\/strong>
\n    GnuPG’nin resmi web sitesinden (gnupg.org) Windows y\u00fckleyicisini indirip kurabilirsiniz.<\/p>\n
Kurulumdan sonra, terminalinizde gpg --version<\/code> komutunu \u00e7al\u0131\u015ft\u0131rarak GnuPG’nin do\u011fru \u015fekilde kurulup kurulmad\u0131\u011f\u0131n\u0131 kontrol edebilirsiniz.<\/p>\n

S\u0131k\u00e7a Sorulan Sorular (SSS)<\/h4>\n
1. GnuPG anahtarlar\u0131m\u0131 nas\u0131l yedeklerim?<\/strong>
\n\u00d6zel anahtarlar\u0131n\u0131z\u0131 yedeklemek hayati \u00f6neme sahiptir. \u00d6zel anahtar\u0131n\u0131z\u0131 kaybetmeniz durumunda, onunla \u015fifrelenmi\u015f verilere veya imzalanm\u0131\u015f dosyalara eri\u015fiminizi kaybedersiniz. \u00d6zel anahtar\u0131n\u0131z\u0131 d\u0131\u015fa aktarmak i\u00e7in:<\/p>\n
gpg --armor --export-secret-keys  > ozel_anahtarim.asc<\/code><\/pre>\n
Bu dosyay\u0131 g\u00fcvenli bir yerde saklay\u0131n (\u00f6rne\u011fin, \u015fifreli bir USB s\u00fcr\u00fcc\u00fcde veya g\u00fcvenli bulut depolama alan\u0131nda). Genel anahtar\u0131n\u0131z\u0131 d\u0131\u015fa aktarmak i\u00e7in ise:<\/p>\n
gpg --armor --export  > genel_anahtarim.asc<\/code><\/pre>\n
2. GnuPG \u00f6zel anahtar\u0131m\u0131n parolas\u0131n\u0131 unutursam ne olur?<\/strong>
\nMaalesef, \u00f6zel anahtar\u0131n\u0131z\u0131n parolas\u0131n\u0131 unutman\u0131z durumunda, anahtar\u0131n\u0131z\u0131 kullanman\u0131z m\u00fcmk\u00fcn olmaz. GnuPG’de parolay\u0131 kurtarman\u0131n bir yolu yoktur. Bu nedenle, anahtar\u0131n\u0131z\u0131 olu\u015ftururken se\u00e7ti\u011finiz parolay\u0131 g\u00fcvenli bir \u015fekilde saklaman\u0131z ve unutmaman\u0131z \u00e7ok \u00f6nemlidir. Parolay\u0131 unuttuysan\u0131z, yeni bir anahtar \u00e7ifti olu\u015fturman\u0131z gerekecektir.<\/p>\n
3. Genel anahtar\u0131m\u0131 anahtar sunucusuna nas\u0131l y\u00fcklerim?<\/strong>
\nGenel anahtar\u0131n\u0131z\u0131 bir anahtar sunucusuna y\u00fcklemek, di\u011fer ki\u015filerin anahtar\u0131n\u0131z\u0131 kolayca bulup sizinle \u015fifreli ileti\u015fim kurmas\u0131n\u0131 veya imzalar\u0131n\u0131z\u0131 do\u011frulamas\u0131n\u0131 sa\u011flar.<\/p>\n
gpg --send-keys <\/code><\/pre>\n
Bu komut, anahtar\u0131n\u0131z\u0131 varsay\u0131lan OpenPGP anahtar sunucusuna y\u00fckler.<\/p>\n
4. python-gnupg<\/code> yerine ba\u015fka Python GPG k\u00fct\u00fcphaneleri var m\u0131?<\/strong>
\nEvet, python-gnupg<\/code> en yayg\u0131n ve olgun k\u00fct\u00fcphanelerden biridir. Ancak, daha d\u00fc\u015f\u00fck seviyeli kriptografik i\u015flemleri veya farkl\u0131 OpenPGP k\u00fct\u00fcphanelerini kullanan ba\u015fka alternatifler de olabilir. Ancak, GnuPG’nin g\u00fcvenilirli\u011fi ve geni\u015f kullan\u0131m\u0131 g\u00f6z \u00f6n\u00fcne al\u0131nd\u0131\u011f\u0131nda, python-gnupg<\/code> \u00e7o\u011fu kullan\u0131m durumu i\u00e7in m\u00fckemmel bir se\u00e7imdir.<\/p>\n
5. GnuPG ile simetrik \u015fifreleme yapabilir miyim?<\/strong>
\nEvet, GnuPG asimetrik \u015fifrelemenin yan\u0131 s\u0131ra simetrik \u015fifrelemeyi de destekler. Simetrik \u015fifrelemede, hem \u015fifreleme hem de \u015fifre \u00e7\u00f6zme i\u00e7in tek bir anahtar (veya parola) kullan\u0131l\u0131r. python-gnupg<\/code> ile do\u011frudan simetrik \u015fifreleme yapmak i\u00e7in gpg.encrypt<\/code> metodunu recipients<\/code> parametresi olmadan ve passphrase<\/code> parametresiyle kullanabilirsiniz. Ancak genellikle GnuPG, anahtar y\u00f6netimi ve g\u00fcven modeli nedeniyle asimetrik \u015fifreleme i\u00e7in tercih edilirken, simetrik \u015fifreleme daha \u00e7ok yerel dosya \u015fifrelemesi gibi durumlar i\u00e7in kullan\u0131l\u0131r.<\/p>\n
