GENKEY(1) Cryptography Utilities GENKEY(1)NAMEgenkey - generate SSL certificates and certificate requests
SYNOPSISgenkey [--test] [--days count] [[--genreq] | [--makeca] | [--nss] |
[--renew] | [--cacert]] {hostname}
DESCRIPTIONgenkey is an interactive command-line tool which can be used to
generate SSL certificates or Certificate Signing Requests (CSR).
Generated certificates are stored in the directory /etc/pki/tls/certs/,
and the corresponding private key in /etc/pki/tls/private/.
When using mod_nss the private key is stored in the nss database.
Consult the nss.conf file in /etc/httpd/conf.d/ for the location of the
database.
genkey will prompt for the size of key desired; whether or not to
generate a CSR; whether or not an encrypted private key is desired; the
certificate subject DN details.
genkey generates random data for the private key using the truerand
library and also by prompting the user for entry of random text.
nss indicates that mod_nss database should be used to store keys and
certificates.
OPTIONS--makeca
Generate a Certificate Authority keypair and certificate.
--genreq
Generate a Certificate Signing Request for an existing private key,
which can be submitted to a CA (for example, for renewal).
--renew
Used with --genreq to indicate a renewal, the existing keypair will
be used. Certs and keys must reside in the nss database, therefore
--nss is also required. Pem file based cert renewal is not
currently supported.
--cacert
The certificate renewal is for a CA, needed for openssl certs only.
--days count
When generating a self-signed certificate, specify that the number
of days for which the certificate is valid be count rather than the
default value of 30.
--test
For test purposes only; omit the slow process of generating random
data.
EXAMPLES
The following example will create a self-signed certificate and private
key for the hostname www.example.com:
# genkey--days 120 www.example.com
The following example will create a self-signed certificate and private
key for the hostname www.nssexample.com which will be stored in cert
and key in the nss database. If no nickname is given the tool will
extract it from mod_nss's nss configuration file.
# genkey--days --nss 120 www.nssexample.com
The following example will generate a certificate signing request for a
new mod_nss style cert specified by its nickname, Server-Cert:
# genkey--genreq --nss --days 120 Server-Cert
The following example will generate a certificate signing request for
the renewal of an existing mod_nss cert specified by its nickname,
Server-Cert:
# genkey--genreq --renew --nss --days 120 Server-Cert
