VCert Python is a Python library and SDK designed to simplify key generation and enrollment of machine identities (also known as SSL/TLS certificates and keys) that comply with enterprise security policy by using the Venafi Trust Protection Platform or Venafi as a Service.
This implementation is based on the original Go library, https://github.com/Venafi/vcert.
VCert supports Python 3, and Python 2.7 (when the future module is installed). VCert releases are tested using the latest version of Trust Protection Platform. The latest VCert release should be compatible with Trust Protection Platform 17.3 or higher based on the subset of API methods it consumes.
Get the library using pip:
pip install vcert
You also can install latest version from github:
pip install https://github.com/Venafi/vcert-python/archive/master.zip
If installation fails collecting dependancies, make sure your python setuptools is up to date. Run the following command to upgrade to the latest version of setuptools.
pip install setuptools -U
For code samples of programmatic use, please review the files in /examples.
- For Trust Protection Platform, the
zoneformat is the DN of a policy with or without the “\VED\Policy” prefix (e.g. “\VED\Policy\Certificates\VCert” or simply “Certificates\VCert”)
- For Venafi as a Service, the
zoneformat is the name of an OutagePREDICT Application and the API Alias of an Issuing Template assigned to it delimited by a single backslash character (e.g. “My Application\My CIT”)
Prerequisites for using with Trust Protection Platform
- A user account that has an authentication token with “certificate:manage,revoke” scope (i.e. access to the “Venafi VCert SDK” API Application as of 20.1) or has been granted WebSDK Access
- A folder (zone) where the user has been granted the following permissions: View, Read, Write, Create, Revoke (for the revoke action), and Private Key Read (for the pickup action when CSR is service generated)
- Policy applied to the folder which specifies:
- CA Template that Trust Protection Platform will use to enroll certificate requests submitted by VCert
- Subject DN values for Organizational Unit (OU), Organization (O), City (L), State (ST) and Country (C)
- Management Type not locked or locked to ‘Enrollment’
- Certificate Signing Request (CSR) Generation not locked or locked to ‘Service Generated CSR’
- Generate Key/CSR on Application not locked or locked to ‘No’
- (Recommended) Disable Automatic Renewal set to ‘Yes’
- (Recommended) Key Bit Strength set to 2048 or higher
- (Recommended) Domain Whitelisting policy appropriately assigned
The requirement for the CA Template to be assigned by policy follows a long standing Venafi best practice which also met our design objective to keep the certificate request process simple for VCert users. If you require the ability to specify the CA Template with the request you can use the TPP REST APIs but please be advised this goes against Venafi recommendations.
Prerequisites for using with Venafi as a Service
- The Venafi as a Service REST API is accessible at https://api.venafi.cloud from the system where VCert will be executed.
- You have successfully registered for a Venafi as a Service account, have been granted at least the “Resource Owner” role, and know your API key.
- A CA Account and Issuing Template exist and have been configured with:
- Recommended Settings values for:
- Organizational Unit (OU)
- Organization (O)
- City/Locality (L)
- State/Province (ST)
- Country (C)
- Issuing Rules that:
- (Recommended) Limits Common Name and Subject Alternative Name to domains that are allowed by your organization
- (Recommended) Restricts the Key Length to 2048 or higher
- (Recommended) Does not allow Private Key Reuse
- Recommended Settings values for:
- An Application exists where you are among the owners, and you know the Application Name.
- An Issuing Template is assigned to the Application, and you know its API Alias.
