Generate Self-Signed Certificate

Create a RSA private key for your CA (will be Triple-DES encrypted and PEM formatted)

openssl genrsa -des3 -out server.key 2048

You can see the details of this RSA private key via the command:

openssl rsa -noout -text -in ca.key

Create a Certificate Signing Request (CSR) with the server RSA private key (output will be PEM formatted):

openssl req -new -key server.key -out server.csr

You can see the details of this CSR via the command

openssl req -noout -text -in server.csr 

You can create a decrypted PEM version (not recommended) of this private key via:

openssl rsa -in ca.key -out ca.key.unsecure

If you want to run apache without a password rename it correctly:

mv server.unsecure server.key

Generate apache mod_ssl certificate:

openssl x509 -req -days 730 -in server.csr -signkey server.key -out server.crt

Verify contents of certificate:

openssl x509 -noout -text -in server.crt

Example

mv ssl.key/server.key ssl.key/server.key.bk
openssl genrsa -des3 -out ssl.key/server.key 2048
openssl rsa -noout -text -in ssl.key/server.key
openssl rsa -in ssl.key/server.key -out ssl.key/server.key.unsecure
mv ssl.key/server.key ssl.key/server.key.bk
mv ssl.key/server.key.unsecure ssl.key/server.key
openssl req -new -key ssl.key/server.key -out ssl.csr/server.csr
openssl req -noout -text -in ssl.csr/server.csr
openssl x509 -req -days 730 -in ssl.csr/server.csr -signkey ssl.key/server.key -out ssl.crt/server.crt
openssl x509 -noout -text -in ssl.crt/server.crt
