DCC1, DCC2?

Good day to all of you,

I have (during a pentest) managed to get some dumps out of the firewall, but to my amazement, I had never seen hashes like this. 

Do you think these are realistic hashes :

first one seems normal, such as a DCC hash: (changed a few letters for sec)

PBzXaJrO7QnfB4XjNmVp8uXyJVjjG8IT

but the second one of a different user:

NrHoFGjPO%2BYpWGhvWJNKZNhPkdYtVf3O (notice the %)

Do you have any idea of what that could be?

Thank you
