DISABLE_REQUEST_SIGNATURE_CHECK_SYSTEM_PROPERTY

public static final java.lang.String DISABLE_REQUEST_SIGNATURE_CHECK_SYSTEM_PROPERTY

The name of the system property that can be used to disable request signature verification. This feature verifies the certificate authenticity using the configured TrustStore and the signature of the skill request, and will throw a SecurityException if the signature does not pass verification. This feature should only be disabled in testing scenarios and never in a production environment.

Constant Field Values

TIMESTAMP_TOLERANCE_SYSTEM_PROPERTY

public static final java.lang.String TIMESTAMP_TOLERANCE_SYSTEM_PROPERTY

The name of the system property that can be used to configure the timestamp tolerance (in millis) of the SkillRequestTimestampVerifier. Requests with timestamps outside of this inclusive tolerance range, either in the past or future, are rejected. If this property is not provided the default value, 30000L, will be used.

Constant Field Values

DEFAULT_TOLERANCE_MILLIS

public static final long DEFAULT_TOLERANCE_MILLIS

Default timestamp offset tolerance value in millis, used if a custom value is not provided through the "com.amazon.speech.speechlet.servlet.timestampTolerance" system property.
