Instanciating rsaKey with key from openssl lib

I want to instanciate an rsa key from a string like the following
"
048dd230b9c480fa1aeaa3dd3ca74cb902ce6ddc5140eb9ab35a16d6d2eec917fde00e616f499
e6ee40545346296f4ac … 86540094c9d55a60446066d97c43f1b61c64b7fed41586cb8d27054c8379e71
"
But there is no comma in the string, and I got an assertion because of that. The format seems different, maybe it’s my lack of experience, but does someone know about this issue?

Thank you
