MQTT publish plain hex

Is it possible to publish to a channel field with raw data?. Say for example after my sensors data are proccessed with aes encryption, Published data looks like:
0x23,0x10,0x01,0xef,0xfa,0x34,0x67,0x04,0x89,0xe3,0xa7,0xcc,0x20,0x07,0xdd,0xef

Hi,
The write() function expects a string as input, so it is not possible to directly pass the raw data as a binary string. In such cases, it becomes necessary to convert the raw data into a string representation before publishing it to the channel field.
