OctoLintSha1CertificatesCheck

OctoLintSha1CertificatesCheck returns a warning if any deployment targets, workers or the Octopus Server itself is using a certificate with an older, SHA-1 certificate which is now considered to be insecure.

Recommendation

Change the certificates used by deployment targets, workers, or the Octopus Server itself to use a SHA-256 certificate algorithm.

See this article for more details.

Remediation

• Ensure all Deployment targets or workers are updated to use SHA-256. To configure a Tentacle to use a new certificate, ensure your Tentacle version is on the latest version and follow the instructions in our docs.
• For the Octopus Server certificate, follow the instructions in our docs.
