Detailed Description

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 Documentation

#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.


Typedef Documentation

WHIRLPOOL-0 uses the same structure than plain WHIRLPOOL.

WHIRLPOOL-1 uses the same structure than plain WHIRLPOOL.


Function Documentation

void sph_whirlpool_init ( void *  cc  ) 

Initialize a WHIRLPOOL context. This process performs no memory allocation.

Parameters:
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.

Parameters:
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.

Parameters:
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().

Parameters:
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.

Parameters:
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.

Parameters:
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().

Parameters:
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.

Parameters:
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.

Parameters:
cc the WHIRLPOOL-1 context
dst the destination buffer
