Como todos devem saber o programa para trabalhar com certificados no Linux é o OpenSSL, então segue os exemplos abaixo:

###Gerando certificado auto assinado
  1. openssl req -new -newkey rsa:2048 -sha256 -nodes > new.cert.req
    Country Name (2 letter code) [AU]: País com duas letras;
    State or Province Name (full name) [Some-State]: Estado por extenso
    Locality Name (eg, city) []:cidade
    Organization Name (eg, company) [Internet Widgits Pty Ltd]: Sempre ICP-Brasil
    Organizational Unit Name (eg, section) []:Nome da empresa ex:Corporação Incolume
    Common Name (e.g. server FQDN or YOUR name) []:FQDN ex:www.incolume.com.br
    Email Address []: email do administrador ex:postmaster@incolume.com.br
    Generating a 2048 bit RSA private key
    ..........................+++
    ..................................................+++
    writing new private key to 'privkey.pem'
    -----
    You are about to be asked to enter information that will be incorporated
    into your certificate request.
    What you are about to enter is what is called a Distinguished Name or a DN.
    There are quite a few fields but you can leave some blank
    For some fields there will be a default value,
    If you enter '.', the field will be left blank.
    -----
    Country Name (2 letter code) [AU]:BR
    State or Province Name (full name) [Some-State]:Distrito Federal
    Locality Name (eg, city) []:BSB
    Organization Name (eg, company) [Internet Widgits Pty Ltd]:ICP-Brasil
    Organizational Unit Name (eg, section) []:Corporação Incolume
    Common Name (e.g. server FQDN or YOUR name) []:www.incolume.com.br
    Email Address []:postmaster@incolume.com.br
    
    Please enter the following 'extra' attributes
    to be sent with your certificate request
    A challenge password []:
    An optional company name []:
    
  2. openssl rsa -in privkey.pem -out new.cert.key
  3. openssl x509 -in new.cert.req -out new.cert.cer -req -signkey new.cert.key -days 365
Exemplo:
  1. openssl req -newkey rsa:2048 -sha256 -nodes -keyout incolume`date +%s`.pem -out incolume`date +%s`.req -subj '/C=BR/ST=Distrito Federal/L=BSB/O=Non ICP-Brasil/OU=incolume.com.br/CN=email.incolume.com.br/emailAddress=postmaster@incolume.br'
  2. openssl rsa -in incolume1429107131.pem -out incolume1429107131.key
  3. openssl x509 -in incolume1429107131.req -out incolume1429107131.cer -req -signkey incolume1429107131.key -days 730
#Somente a chave e a requisição
#openssl req -newkey rsa:2048 -sha256 -nodes -keyout x.key -out x.req -subj '/C=BR/ST=Distrito Federal/L=BSB/O=ICP-Brasil/OU=incolume.com.br/CN=www.incolume.com.br/emailAddress=postmaster@incolume.com.br'
Ou
#openssl req -new -newkey rsa:2048 -sha256 -nodes -subj '/C=BR/ST=Distrito Federal/L=BSB/O=ICP-Brasil/OU=Incolume.com.br/CN=www.incolume.com.br/emailAddress=postmaster@incolume.com.br' -keyout www4-`date +%F`.key -out www4-`date +%F`.req
Ou
SITE=incolume #openssl req -new -newkey rsa:2048 -sha256 -nodes -subj "/C=BR/ST=Distrito Federal/L=BSB/O=ICP-Brasil/OU=Incolume/CN=*.${SITE}.com.br/emailAddress=postmaster@incolume.com.br" -keyout ${SITE}-`date +%F`.key -out ${SITE}-`date +%F`.req
