onde o rpm instala chaves gpg personalizadas?

Onde o CentOS / RHEL 6 armazena chaves gpg personalizadas? Eu pensei em / etc / pki / rpm-gpg, mas instalei a chave do nginx, mas não consegui encontrá-la. Vejo que foi importado corretamente, mas onde está?

wget http://nginx.org/keys/nginx_signing.key
rpm --import nginx_signing.key

-----END PGP PUBLIC KEY BLOCK-----

Eles são armazenados no banco de dados RPM, que está em / var / lib / rpm . Da página de manual

Digital signatures cannot be verified without a public key.  An ASCII armored public  key  can  be added  to  the rpm database using --import. An imported public key is carried in a header, and keyring management is performed exactly like package management. For example, all currently  imported public keys can be displayed by:

rpm -qa gpg-pubkey*

Details about a specific public key, when imported, can be displayed by querying.  Here’s information about the Red Hat GPG/DSA key:

rpm -qi gpg-pubkey-db42a60e

Finally, public keys can be erased after importing just like packages. Here’s how  to  remove  the Red Hat GPG/DSA key

rpm -e gpg-pubkey-db42a60e

/ etc / pki / rpm-gpg é o local padrão para pacotes com configuração de repositório (como epel-release ) para colocar as chaves que eles querem que sejam importados. A configuração do yum no pacote terá o caminho para a chave na diretiva gpgkey . Na primeira vez que você tenta instalar um pacote a partir de um repositório, o yum solicita que você importe a chave.
