Commonly manage certificates in both Venafi and CredHub.
CredHub-Venafi is a CLI tool (cv) that helps manage certificates located in Venafi TPP and Pivotal Cloud Foundry CredHub.
- login
- create
- list
- delete
- Logs into CredHub only.
- TPP authentication happens with each command.
CV logs in the User Account and Authentication (UAA) Server by first contacting the CredHub Server. It retrieves the UAA path. Then, it contacts the UAA server with the credentials to get an access token. That token is subsequently used to access the CredHub server.
The config file is read from the .cv.conf in the $HOME directory.
vcert_username: tppadmin
vcert_password: topsecret
vcert_zone: \Certificates
vcert_base_url: https://yourvenafiinstall.com/vedsdk/
connector_type: tpp
credhub_username: credhub
credhub_password: topsecret
credhub_endpoint: https://127.0.0.1:9000
skip_tls_validation: true
log_level: status
./cv login \
-url "https://127.0.0.1:9000" \
-u "credhub" \
-p "password" \
-skip-tls-validation
After logging in to CredHub there will be a file at $HOME/.cv/json.config that contains the token and CredHub login settings.

Create a certificate on the Venafi side and upload to CredHub
./cv create -cn "atestcert3" -name "mycertfromvenafi26"
Create a certificate on the Credhub and upload to Venafi
./cv create \
-credhub \
-name mycredname28 \
-cn mycredname28 \
-key-usage data_encipherment \
-ext-key-usage client_auth \
-ca "/aname"
Uses -credhub flag.
Adding the -h flag to command reveals the help associated with that command.
i.e.
Usage of cv:
-bycommonname
Compare by certificate common name from Venafi and file basename on the CredHub side.
-bypath
Compare by path
-bythumbprint
Compare by thumbprint. Note this will be slower due to the need to download each cert from CredHub.
-cprefix string
Credhub prefix to strip from returned values
-croot string
Subpath to search in CredHub
-vlimit int
(Default 100) Limits the number of Venafi results returned (default 100)
-vprefix string
Venafi prefix to strip from returned values
-vroot string
Subpath to search in Venafi
The policy folder is configured with the vcert_zone key.
vcert_zone: \Certificates
Compare by thumbprint
cv list -bythumbprint \
-vroot "\\VED\\Policy\\Certificates\\Division 3\\"
Compare by CommonName
cv list -bycommonname \
-vroot "\\VED\\Policy\\Certificates\\Division 3\\"</pre>
Compare by path
cv list -bypath \
-vroot "\\VED\\Policy\\Certificates\\Division 3\\"</pre>
Compare by thumbprint
cv list -bythumbprint \
-vroot "\\VED\\Policy\\Certificates\\Division 3\\"</pre>
This mode takes the provided thumbprint on the Venafi side and on the CredHub side it lists and then pulls and computes the thumbprint for each credential because CredHub does not provide the thumbprint.
Compare by CommonName
cv list -bycommonname \
-vroot "\\VED\\Policy\\Certificates\\Division 3\\"</pre>
Compares CommonName from the Venafi side with basename on the CredHub side. (i.e the last segment of path "/credhubpath/thebasename")
Compare by path basename
Compares path from Venafi side with path from the CredHub side. There are command line options for removing portions of the prefix on each side.
Deletes a certificate on both systems by first looking it up from the CredHub side by name, calculating the thumbprint and deleting from the Venafi side.
CredHub-Venafi is maintained and funded by New Context, which provides "security first" automation to mission critical infrastructure. We were doing DevSecOps before it became a buzzword, you can hire us to improve your time-to-market, reduce risk, and boost your security/compliance posture.
