056 /**
057 * This class defines an API that must be implemented by extensions which
058 * provide access to trust managers which are used to determine whether to trust
059 * a certificate that has been presented to the server. Trust managers are
060 * generally used when performing cryptographic operations, including SSL and
061 * StartTLS communication, in which a certificate is presented to the server.
062 * In such cases, the secure communication will only be allowed if the trust
063 * managers determine that the presented certificate chain is trustworthy.
064 * <BR>
065 * <H2>Configuring Trust Manager Providers</H2>
066 * In order to configure a trust manager provider created using this API, use a
067 * command like:
068 * <PRE>
069 * dsconfig create-trust-manager-provider \
070 * --provider-name "<I>{provider-name}</I>" \
071 * --type third-party \
072 * --set enabled:true \
073 * --set "extension-class:<I>{class-name}</I>" \
074 * --set "extension-argument:<I>{name=value}</I>"
075 * </PRE>
076 * where "<I>{provider-name}</I>" is the name to use for the trust manager
077 * provider instance, "<I>{class-name}</I>" is the fully-qualified name of the
078 * Java class that extends
079 * {@code com.unboundid.directory.sdk.common.api.TrustManagerProvider}, and
080 * "<I>{name=value}</I>" represents name-value pairs for any arguments to
081 * provide to the trust manager provider. If multiple arguments should be
082 * provided to the trust manager provider, then the
083 * "<CODE>--set extension-argument:<I>{name=value}</I></CODE>" option should be
084 * provided multiple times.
