Very simple implementation of a DGB hash function, written in C. Accepts one contiguous string, provided as a command line argument, as input. For example: #./dgb_hash plaintext

dgb_hash.c

#include <stdio.h>
#include <string.h>

int main(int argc, char* argv[])
{
    if (argc != 2)
    {
        printf("\nCorrect usage is: gdb_script plaintext\n");
        return 1;
    }
    
    char* plainText = argv[1];
    int length = strlen(plainText);
    int hash = 5381;
    printf("\nThis is your plaintext: %s\n", plainText);
    printf("\nThis is your hash value:\n");
    for (int i = 0; i < length; i++)
    {
        hash = (((hash << 5) + hash) + plainText[i]) - 'a'; 
        if (i == (length - 1)) printf(" %d\n", hash);
        else printf(" %d", hash);
    }
   
    return 0;  
}
