Subject: allocating salts
Hi,
Which way of the following ways of handling salts is better / preferred.
Given,
static struct custom_salt {
unsigned char userid[8 + 1];
char unsigned hash[8];
} *salt_struct;
1. #define SALT_SIZE sizeof(*salt_struct) and malloc'ing custom_salt
structure for every salt (involves a single pointer copy but leaks
memory) in get_salt().
2. #define SALT_SIZE sizeof(struct custom_salt) and have a static
custom_salt structure (involves whole buffer copy but doesn't leak
memory)
