Calculate a hash using an algorithm proposed by Donald E Knuth in The Art Of Computer Programming Volume 3, under the topic of sorting and search in Chapter 6.4.
- Parameters
-
| data | A pointer to the data. |
| length | The length of the data. |
- Returns
- A 32-bit hash of the data.
◆ DJBHash()

Calculate a hash using an algorithm produced by Professor Daniel J Bernstein and shown first to the world on the USENET newsgroup comp.lang.c.
It is one of the most efficient hash functions ever published.
- Parameters
-
| data | A pointer to the data. |
| length | The length of the data. |
- Returns
- A 32-bit hash of the data.
◆ ELFHash()

Calculate a hash using an algorithm that is based on work by Peter J Weinberger of AT&T Bell Labs, but is optimized for 32-bit processors.
It's the hash function widely used on most UNIX systems.
- Parameters
-
| data | A pointer to the data. |
| length | The length of the data. |
- Returns
- A 32-bit hash of the data.
◆ SDBMHash()
| uint32_t SDBMHash |
( |
const byte_t * |
data, |
|
|
size_t |
length |
|
) |
| |
|
static |
Calculate a hash using an algorithm that is used in the open source SDBM project.
- Parameters
-
| data | A pointer to the data. |
| length | The length of the data. |
- Returns
- A 32-bit hash of the data.
