Generating a 1024 bit RSA private key
........................++++++
.............................++++++
writing new private key to 'privkey.pem'
Enter PEM pass phrase:1234567890
Verifying - Enter PEM pass phrase:1234567890
-----

2.openssl rsa -in privkey.pem -out server.key
Enter pass phrase for privkey.pem:1234567890
writing RSA key

3.rm privkey.pem

4.openssl req -x509 -in server.req -text -key server.key -out server.crt

5.chmod og-rwx server.key
