Python Setup

Create a virtual environment and install required modules into it

1. python3 -m venv cli_env
2. source cli_env/bin/activate
3. pip install -r requirements.txt

Invoke the tool

python cse_cmd.py -h

Sample steps to upload keys/certs for CSE

1. Create a directory for storing all wrapped private keys.
   Ex: $root/wrapped_keys
   

• The wrapped private key file for each user should have basename as email-id and a '.wrap' extension.
  Ex: $root/wrapped_keys/user1@example.com.wrap
• The wrapped private key file should have a json object with two required fields:
  

  { 
    'kacls_url': 'url of kacls configured in CSE Admin Console', 
    'wrapped_private_key': 'wrapped private key bytes' 
  } 
  

2. Create a directory for storing all certificates in p7 pem format.
   Ex: $root/p7pem_certs
   

• The certificate file should contain the full chain to root CA and should have basename as email-id and a '.p7pem' extension. Ex: $root/p7pem_certs/user1@example.com.p7pem
• If you have p7b file, you can use the following openssl command to convert it to a p7 pem format:
  openssl pkcs7 -inform DER -in {old_name.p7b} -outform PEM -out {new_name.p7pem}

3. Note that all commands require the following argument
   --creds: a json file contains credentials to the service account created in you GCP project. After creating a service account, you can download the credentials to that account to a json file, which you will use here.
   Ex: stored at $root/svc_acct_creds.json
   

4. Easiest is to run the 'insert' command to insert key pairs and identities. Ex:
   

      python cse_cmd.py insert
      --creds $root/svc_acct_creds.json 
      --inkeydir $root/wrapped_keys 
      --incertdir $root/p7pem_certs 

• alternatively, you could run insert_keypair, note down the keypair id and then run insert_identity using that keypair id. You can also get the keypair id by running list_keypair command.

5. You can check if user has a valid cse keypair or identity by running
   list_keypair and/or list_identity
