WHIRLPOOL interface.
WHIRLPOOL knows three variants, dubbed "WHIRLPOOL-0" (original version, published in 2000, studied by NESSIE), "WHIRLPOOL-1" (first revision, 2001, with a new S-box) and "WHIRLPOOL" (current version, 2003, with a new diffusion matrix, also described as "plain WHIRLPOOL"). All three variants are implemented here.
The original WHIRLPOOL (i.e. WHIRLPOOL-0) was published in: P. S. L. M. Barreto, V. Rijmen, "The Whirlpool Hashing Function", First open NESSIE Workshop, Leuven, Belgium, November 13--14, 2000.
The current WHIRLPOOL specification and a reference implementation can be found on the WHIRLPOOL web page: http://paginas.terra.com.br/informatica/paulobarreto/WhirlpoolPage.html

#define SPH_SIZE_whirlpool 512 |
Output size (in bits) for WHIRLPOOL.
#define SPH_SIZE_whirlpool0 512 |
Output size (in bits) for WHIRLPOOL-0.
#define SPH_SIZE_whirlpool1 512 |
Output size (in bits) for WHIRLPOOL-1.
WHIRLPOOL-0 uses the same structure than plain WHIRLPOOL.
WHIRLPOOL-1 uses the same structure than plain WHIRLPOOL.
void sph_whirlpool_init | ( | void * | cc | ) |
Initialize a WHIRLPOOL context. This process performs no memory allocation.
cc | the WHIRLPOOL context (pointer to a sph_whirlpool_context ) |
void sph_whirlpool | ( | void * | cc, | |
const void * | data, | |||
size_t | len | |||
) |
Process some data bytes. It is acceptable that len
is zero (in which case this function does nothing). This function applies the plain WHIRLPOOL algorithm.
cc | the WHIRLPOOL context | |
data | the input data | |
len | the input data length (in bytes) |
void sph_whirlpool_close | ( | void * | cc, | |
void * | dst | |||
) |
Terminate the current WHIRLPOOL computation and output the result into the provided buffer. The destination buffer must be wide enough to accomodate the result (64 bytes). The context is automatically reinitialized.
cc | the WHIRLPOOL context | |
dst | the destination buffer |
void sph_whirlpool0_init | ( | void * | cc | ) |
Initialize a WHIRLPOOL-0 context. This function is identical to sph_whirlpool_init()
.
cc | the WHIRLPOOL context (pointer to a sph_whirlpool0_context ) |
void sph_whirlpool0 | ( | void * | cc, | |
const void * | data, | |||
size_t | len | |||
) |
Process some data bytes. It is acceptable that len
is zero (in which case this function does nothing). This function applies the WHIRLPOOL-0 algorithm.
cc | the WHIRLPOOL context | |
data | the input data | |
len | the input data length (in bytes) |
void sph_whirlpool0_close | ( | void * | cc, | |
void * | dst | |||
) |
Terminate the current WHIRLPOOL-0 computation and output the result into the provided buffer. The destination buffer must be wide enough to accomodate the result (64 bytes). The context is automatically reinitialized.
cc | the WHIRLPOOL-0 context | |
dst | the destination buffer |
void sph_whirlpool1_init | ( | void * | cc | ) |
Initialize a WHIRLPOOL-1 context. This function is identical to sph_whirlpool_init()
.
cc | the WHIRLPOOL context (pointer to a sph_whirlpool1_context ) |
void sph_whirlpool1 | ( | void * | cc, | |
const void * | data, | |||
size_t | len | |||
) |
Process some data bytes. It is acceptable that len
is zero (in which case this function does nothing). This function applies the WHIRLPOOL-1 algorithm.
cc | the WHIRLPOOL context | |
data | the input data | |
len | the input data length (in bytes) |
void sph_whirlpool1_close | ( | void * | cc, | |
void * | dst | |||
) |
Terminate the current WHIRLPOOL-1 computation and output the result into the provided buffer. The destination buffer must be wide enough to accomodate the result (64 bytes). The context is automatically reinitialized.
cc | the WHIRLPOOL-1 context | |
dst | the destination buffer |
