A list of certificate public keys that should be distrusted by Google Chrome for TLS server authentication. The policy value is a list of base64-encoded X.509 certificates. Any certificate with a matching SPKI (SubjectPublicKeyInfo) will be distrusted. Example value: 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
Registry
Software\Policies\Google\Chrome Software\Policies\Google\Chrome Export Builder
BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
