self-signed apache certificate
Generate private key:
openssl genrsa -des3 -out server.key 1024
Generate csr (Certificate Signing Request)
openssl req -new -key server.key -out server.csr
Remove passphrase from key
cp server.key server.key.org
openssl rsa -in server.key.org -out server.key
openssl rsa -in server.key.org -out server.key
Generate self-signed chertificate
openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
Install new certificate under gentoo
cp server.crt /etc/apache2/ssl/server.crt
cp server.key /etc/apache2/ssl/server.key
cp server.key /etc/apache2/ssl/server.key
or in newer versions:
cp server.crt /etc/ssl/apache2/server.crt
cp server.key /etc/ssl/apache2/server.key
After restarting apache, it should all be ok.
