接，对nizk-test进行操作。

nizk-test.c内容为：

#pragma oncestruct Input {    int a;};struct NIZKInput {    int b1;    int b2;    int b3;    int b4;};struct Output {    int c1;    int c2;    int c3;};void outsource(struct Input *input, struct NIZKInput *nizkinput, struct Output *output);#if 17void outsource(struct Input *input, struct NIZKInput *nizkinput, struct Output *output){    	output->c1 = input->a + nizkinput->b1;    	output->c3 = input->a + nizkinput->b3;}#elsevoid outsource(struct Input *input, struct Output *output){    	output->c1 = input->a;    	output->c3 = input->a + 3;}#endif

一、生成nizk-test.c对应的circuit

python ../src/vercomp.py nizk-test.c --arith nizk-test.arith --ignore-overflow False --progress True

生成的nizk-test.arith内容为：

total 13input 0                                  # inputinput 1                                  # one-inputnizkinput 2                              # inputnizkinput 3                              # input (unused)nizkinput 4                              # inputnizkinput 5                              # input (unused)const-mul-0 in 1 <1> out 1 <6>           # zeroadd in 2 <0 2> out 1 <7>                 # ArithBusReq.AddReq(DFG.Input,DFG.NIZKInput)const-mul-0 in 1 <1> out 1 <8>           # constant 0add in 2 <0 4> out 1 <9>                 # ArithBusReq.AddReq(DFG.Input,DFG.NIZKInput)mul in 2 <1 7> out 1 <10>                # output-castoutput 10                                # mul in 2 <1 8> out 1 <11>                # output-castoutput 11                                # mul in 2 <1 9> out 1 <12>                # output-castoutput 12                                #

配置相应的input文件nizk-test.in：

0 51 12 13 24 35 4

二、生成相应的公私钥

pinocchio-v0.5.3.exe --qap --pv --nizk --file circuit/nizk-test.arith --mem 4 --input circuit/nizk-test.in --output circuit/nizk-test.out --keys test-nizk-key --genkeys

对应的输出为：

三、生成proof文件

pinocchio-v0.5.3.exe --qap --pv --nizk --file circuit/nizk-test.arith --mem 4 --input circuit/nizk-test.in --output circuit/nizk-test.out --keys test-nizk-key --dowork

输出内容为：

10 000000000000000000000000000000000000000000000000000000000000000611 000000000000000000000000000000000000000000000000000000000000000012 0000000000000000000000000000000000000000000000000000000000000008

四、Verify

pinocchio-v0.5.3.exe --qap --pv --nizk --file circuit/nizk-test.arith --mem 4 --input circuit/nizk-test.in --output circuit/nizk-test.out --keys test-nizk-key --verify

对应的输出为Verification passed通过。
