BinaryEqualsIfExists

BinaryEqualsIfExists compares a binary value in a request to a list of base64-encoded string representations in your policy. There are no known binary context keys, but this is put here for completeness.

To match a request, the context key can be absent, but if present it must match at least one of the base64-encoded string representations in your policy.

You can NOT use policy variables in the value of this operator.
