Description

During setup of new NiFi instance on server I decided to encrypt the its configuration. It seemed to work well, at least there were no errors given during encryption:

nifi-toolkit-1.16.1/bin/encrypt-config.sh \
    -n "$nifi_props" \
    -l "$login_identity_providers" \
    -a "$authorizers" \
    -b "$bootstrap_conf" \
    -S "$scheme" \
    -p "$passwd" \
    -w "$props_key" \
    -m

However when I started the NiFi instance I saw following message in the "nifi-bootstrap.log" file:

2022-05-11 11:08:57,700 ERROR [NiFi logging handler] org.apache.nifi.StdErr Failed to start web server: Error creating bean with name 'niFiWebApiConfiguration': BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'metaDataSourceAdvisor': Cannot resolve reference to bean 'methodSecurityMetadataSource' while setting constructor argument; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.security.config.annotation.method.configuration.GlobalMethodSecurityConfiguration': Unsatisfied dependency expressed through method 'setObjectPostProcessor' parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.apache.nifi.web.security.configuration.AuthenticationSecurityConfiguration': Unsatisfied dependency expressed through constructor parameter 2; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'authorizer': FactoryBean threw exception on object creation; nested exception is org.apache.nifi.properties.SensitivePropertyProtectionException: Protection Scheme [aes/gcm/256] not supported
2022-05-11 11:08:57,701 ERROR [NiFi logging handler] org.apache.nifi.StdErr Shutting down...

In the "nifi.properties" I have following:

nifi.sensitive.props.key=...
nifi.sensitive.props.key.protected=aes/gcm/256
nifi.sensitive.props.algorithm=NIFI_PBKDF2_AES_GCM_256
nifi.sensitive.props.additional.keys=

Why is it that the standard AES_GCM encrypted instance fails to starts with message: "Protection Scheme [aes/gcm/256] not supported"?

There's nothing in the documentation that states otherwise.
https://nifi.apache.org/docs/nifi-docs/html/toolkit-guide.html#AES_GCM
The toolkit guide says nothing about this being unsupported.
