# WhitelistTrustManagerProvider

`object WhitelistTrustManagerProvider : Provider`

Custom Security Provider that forces the TrustManagerFactory to be our custom one. Also holds the identity of the original TrustManager algorithm so that we can delegate most of the checking to the proper Java code. We simply add some more checks.

The whitelist automatically includes the local server DNS name and IP address

### Properties

originalTrustProviderAlgorithm | `val originalTrustProviderAlgorithm: String`
whitelist | `val whitelist: Set<String>`

### Functions

addWhitelistEntries | `fun addWhitelistEntries(serverNames: List<String>): Unit` Adds a list of servers to the whitelist and also adds their fully resolved name/ip address after DNS lookup If the server name is not an actual DNS name this is silently ignored. The DNS request may block the calling thread.
addWhitelistEntry | `fun addWhitelistEntry(serverName: String): Unit` Adds an extra name to the whitelist if not already present If this is a new entry it will internally request a DNS lookup which may block the calling thread.
