CA Introduction




Build the CA server (data encryption transfer for Web services)



CA Server (172.40.55.10)

First step: Configure the CA signing environment

Step two: Generate the private key for the CA server

Step three: Create a root certificate for the CA server

Fourth step: Publish the root certificate file


First step: Configure the CA signing environment

[Email protected] ~]# RPM-QF/ETC/PKI/TLS/OPENSSL.CNF

Openssl-1.0.1e-42.el6.x86_64

[Email protected] ~]#


Vim/etc/pki/tls/openssl.cnf

[Ca_default]

Dir =/etc/pki/ca

Certs = $dir/certs

Certificate? = $dir The title of/MY-CA.CRT root certificate

Private_key? = $dir/private/my-ca.key private key Name


[Req_distinguished_name]

Countryname_default = CN Country

Stateorprovincename_default = Beijing province

Localityname_default = Beijing city

0.organizationname_default = Tarena Unit

: Wq


Build Index.txt, serial files as needed

[Email protected] ~]# CD/ETC/PKI/CA

[email protected] ca]# Touch index.txt

[Email protected] ca]# echo > serial


Step two: Generate the private key for the CA server

cd/etc/pki/ca/private/

OpenSSL genrsa-des3 2048 > My-ca.key (123456 password)

chmod My-ca.key


Step three: Create a root certificate for the CA server

cd/etc/pki/ca/

OpenSSL req-new-x509-key private/my-ca.key-days 365 > my-ca.crt (enter the password for the private key)


[email protected] ca]# OpenSSL req-new-x509-key private/my-ca.key-days 365 > MY-CA.CRT

Enter Pass phrase for Private/my-ca.key:

You is about-to is asked to-enter information that'll be incorporated

into your certificate request.

What's about-to-enter is called a distinguished Name or a DN.

There is quite a few fields but can leave some blank

For some fields there would be a default value,

If you enter '. ', the field would be a left blank.

-----

Country Name (2 letter code) [CN]:

State or province name (full name) [Beijing]:

Locality Name (eg, city) [Beijing]:

Organization Name (eg, company) [Tarena]:

Organizational Unit Name (eg, section) []:mis

Common name (eg, your name or your server ' s hostname) []:ca.tarena.com

Email Address []:[email protected]

[Email protected] ca]#



Fourth step: Publish the root certificate file

cd/etc/pki/ca/

CP my-ca.crt/var/www/html/

Service httpd Restart

3 CA server issues certificates and shares issued certificates

cd/etc/pki/ca/certs/

OpenSSL CA-IN/ROOT/WWW.CSR > Www.crt


[email protected] certs]# OpenSSL CA-IN/ROOT/WWW.CSR > Www.crt

Using Configuration From/etc/pki/tls/openssl.cnf

Enter Pass phrase For/etc/pki/ca/private/my-ca.key:

Check that the request matches the signature

Signature OK
