Look my program read all lines from (plain.txt) and save temporary every read strings line by line into another text called(all.txt), i made the md5sum hash on each line separately of (all.txt) and saving this hashes on calculating.txt... then delete the all.txt and calculating.txt, creating a new copy of calculating (hashes.txt)
I want to do this process one-way only with the command
with array or something without using files.
echo -n (read string line) | openssl md5plain.txt

FILE *read_fp;
FILE *read_tmp;

char hash[1024] = "openssl dgst -md5 all.txt >> calculating.txt";
char buffer[1024];
char line[128];
if ((fp = fopen(Plain, "r")) == NULL){
perror (Plain);
return (EXIT_FAILURE);
}
printf("\tCreating Hash Table. Please wait....\n" );
while(!feof(fp))
{
fscanf(fp,"%s", &line);
read_tmp = fopen("all.txt","w+");
fprintf(read_tmp,"%s", &line);
fclose(read_tmp);
read_fp = popen(hash,"r");
if (read_fp != NULL) {
while ((chars_read = fread(buffer, sizeof(char), 1024 , read_fp)) > 0 ){
}
pclose(read_fp);
}
}
fclose(fp);
system("sed '$d' calculating.txt > hashes.txt");
system("rm all.txt");
system("rm calculating.txt");
printf("Hashes Calculated Successfully... [OK!]\n");
return 0;
