Edit existing C++ CUDA code/kernel

Change input from uint64_t to something what accepts bigger value Change output(before!!! hashing) from decimal to base58 The base58 conversion needs to be done in device-code/function.(like the decimal-conversion now is done). The source: [login to view URL] Right now it you can specify two things: Message(suffix of the string to hash), Starting-point(number to start with). The output looks something like this(no real values, just for example): input Message: AAAA Start: 1 Nonce : 6532178305AAAA hash: 00T74d5088db305c99c5820fc7296809f15b9cd57376b68752a9b8eb19b8d907 I need it modified as follows: Start is limited to an number between 1 and 18,446,744,073,709,551,615. This should be unlimited, or much higher. Output nonce is decimal + message; I need it to be base58 + Message For example: input Message: AAAA Start(starting point of incremental search): 651478901478612308976786789016467 output on terminal: 651478901478612308976789374567881 Nonce base58: f4HAE3AAAA hash: 00F84d5088db305c99c5820fc7296809f15b9cd57376b68752a9b8eb19b8d907 651478901478612339017348461283944 Nonce base58: g6ej12MAAAA hash: 00Z829dd9ea3e4bc119a0df92b55efnda737cade234010bc55df200aa924bbce
