# Description
I need a command that will transform hex string into bytes and into
other direction.
I've implemented `decode hex` command and `encode hex` command. (Based
on `encode base64` and `decode base64` commands
# User-Facing Changes
```
> '010203' | decode hex
0x[01 02 03]
```
and
```
> 0x[01 02 0a] | encode hex
'01020A'
```
