Specifies if the payload will be signed with the V4 signature. This provides added security but MCP needs to read the entire payload, so it will impact the performance. This only applies if the V4 signature is enabled through the parameter [msml].record.amazonsignatureversion. When set to 'true', MCP will calculate the Hash SHA256 of the Amazon POST payloads, and use the result to create the signature. When set to 'false', MCP won't calculate the payload hash.
