Created March 8, 2019 15:38
Powershell to generate self-signed SQL Server TLS certificate
# Create Self Signed RSA Cert for SQL Server usage
#
# Customize:
# + -Subject should contain hostname (or virtal name for FCI)
# + -FriendlyName is anything which helps you to recognize the key
# + -DnsName should list all variants (FQDN) of hostnames used by clients (VIP+Machines)
# + -NotAfter set expire accoring to your policy
# + (Non)Exportable is more secure but harder to manage
#
# - Using RSASSA-PSS (-AlternateSignatureAlgorithm) does not work with Java 8 clients:
