SSL was developed by Netscape in 1995 for internet security. SSL/TLS encrypts data, performs authentication, and ensures data integrity. SSL was updated to TLS in 1999 by the IETF. SSL 3.0 (1996) is considered deprecated and no longer supported
TLS is mandatory for transport layer and optional for REST layer. Certificates can be in PEM format or JKS/PKCS12/PFX format. Node certificates are required for cluster communication. Super admin certificates needed for security plugin configuration
Secure storage for API keys, passwords, certificates and sensitive data. Cloud IAM roles enable least privilege principle for secret management. First-class versioning with pinning and automatic rotation. Built-in Cloud Audit Logs for compliance monitoring. Data encrypted with TLS in transit and AES-256-bit at rest
Apple Developer Program membership required for certificate requests. Xcode preferred for most certificate requests. Distribution certificates available only to Account Holders and Admins
Windows uses unique volume references like \Device\HarddiskVolume3 for data organization. Volume references help Windows identify and access volume contents. Volume references are used in error messages when fixing file access issues
Cross Certificates create alternate trust paths for certificates. Useful for legacy devices with older, more ubiquitous roots. Code Signing Cross Certificates chain to Microsoft Trust Store
