PRE-CONFIGURATION

Configuration files

serial.csv

serial
test1
test2
test3

config.ini

Create default folder

• May require sudo

• Default folder => $HOME/Documents/CertGenerator/

• copy default csv file to $HOME/Documents/CertGenerator/csv/serial.csv

• copy yaml file to $HOME/Documents/CertGenerator/csr.yaml

$ sudo cert init

To change default folder or default csv:

• May require sudo

$ sudo cert init -cert [path/of/folder] -csv [path/of/csv/file]

or

$ sudo cert config edit -cert [path/of/folder] -csv [path/of/csv/file]

To edit yaml file:

• Enter the desired subject

• Enter “-” to keep empty

• If you want to create multiple csr using serial.csv, don’t use Commmon Name => just enter “-” to keep empty

• Note: You always have old csr.yaml in folder under format csr.yam_[date od modification]

$ cert config edit-yaml

CONFIGURATION

Create csr

Create one csr

• Use -c if you want to use csr.yaml to create csr

• Use -f to overwrite existing csr

• The key and csr files will be created in {folder}/certificate/csr/

• Example: With the command below it will create

  • {folder}/certificate/csr/test/test.csr

  • {folder}/certificate/csr/test/test.key

$ cert create test -c [-f]

Create multiple csr

• Use -c if you want to use csv file and csr.yaml

• Use -f to overwrite existing csr

* cert create-multiple -c [-f]

Create p12

Create one p12

• You need pem file and key file:

• Use -f to overwrite existing p12

$ cert create-p12 test.p12 [-f] --pem [path/of/pem file] --key [path/of/key file] -pass [password(default:3z6F2Xfc)]

Create multiple p12

• for creating multiple p12: pem file, key file and p12 must have the same name

• Use -f to overwrite existing p12

• Example if you create test1.p12 test2.P12 …:

  • In the csv file, you must have test1 test2 …

  • The pem files must be test1.pem test2.pem …

  • The key files must be test1.key test2.key …

  • It will search key files in folder/certificate/csr/

$ cert create-multiple-p12 -c [-f] --pem-folder [path/of/pem folder]

If you want to use an other folder to search key files, add –key-folder:

$ cert create-multiple-p12 -c [-f] --pem-folder [path/of/pem folder] --key-folder [path/of/key folder]
