Module certstore 

The OS store of trusted root certificates (Windows), for TLS clients. The operating system’s trusted root certificates, for TLS clients.

• Windows: the ROOT system store of the current user (which includes the machine roots), read with CertOpenSystemStoreW and CertEnumCertificatesInStore from crypt32.
• Elsewhere: nothing here; Unix systems keep their roots in PEM bundles (/etc/ssl/..., SSL_CERT_FILE), which simoom-tls reads itself. macOS ships /etc/ssl/cert.pem with the system roots, so the bundle path covers it too.

Functions

system_roots

DER-encoded root certificates from the OS store (empty where the OS has no such store or it cannot be opened).
