Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versionconfiguring-certificate-authority-with-opensslExecute the skills CLI command in your project's root directory to begin installation:
Fetches configuring-certificate-authority-with-openssl from mukul975/Anthropic-Cybersecurity-Skills and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate configuring-certificate-authority-with-openssl. Access via /configuring-certificate-authority-with-openssl in your agent's command palette.
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

A Certificate Authority (CA) is the trust anchor in a PKI hierarchy, responsible for issuing, signing, and revoking digital certificates. This skill covers building a two-tier CA hierarchy (Root CA + Intermediate CA) using OpenSSL and the Python cryptography library, including CRL distribution, OCSP responder configuration, and certificate policy management.
Root CA (offline, air-gapped)
|
+-- Intermediate CA (online, operational)
|
+-- Server Certificates
+-- Client Certificates
+-- Code Signing Certificates
| Extension | Purpose | Critical |
|---|---|---|
| basicConstraints | CA:TRUE/FALSE, pathLenConstraint | Yes |
| keyUsage | keyCertSign, cRLSign, digitalSignature | Yes |
| extendedKeyUsage | serverAuth, clientAuth, codeSigning | No |
