The other replies give you the method using binary and this
works. I use a shortcut that involves a nibble table by
observing that 0x1 translates to 0x8 etc.:
        0x1 <-> 0x8 0x6 <-> 0x6
        0x2 <-> 0x4 0x9 <-> 0x9
        0x3 <-> 0xc 0xf <-> 0xf
        0x5 <-> 0xa 0x0 <-> 0x0
        0x7 <-> 0xe
        0xb <-> 0xd

Using one of the examples: 00-d0-97-85-88-00
Substitute the table value: 00-b0-e9-1a-11-00
Swap the nibbles: 00-0b-9e-a1-11-00

This works canonical to non-canonical or vice-versa.
And can be used by those who are hex impaired.

HTH, Fred.
