An example of output is composed of 128 bytes, that means 128x8 bits, so 1024 bits :
"401b09eab3c013c48a54922bb802bec8fd531819211125f201d8b3727429090fb337591abd3e44453b954555b7a0812e1081c39b740293f765eae731f59d3ed1"
You could then copy and paste this generated key into your Token Validation Handler if needed for this purpose...
