Detailed Description

PANAMA interface.

PANAMA has been published in: J. Daemen and C. Clapp, "Fast Hashing and Stream Encryption with PANAMA", Fast Software Encryption - FSE'98, LNCS 1372, Springer (1998), pp. 60--74.

PANAMA is not fully defined with regards to endianness and related topics. This implementation follows strict little-endian conventions:

With these conventions, PANAMA is sometimes known as "PANAMA-LE". The PANAMA reference implementation uses our conventions for input, but prescribes no convention for output.

Define Documentation

#define SPH_SIZE_panama   256

Output size (in bits) for PANAMA.


Function Documentation

void sph_panama_init ( void *  cc  ) 

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

Parameters:
cc the PANAMA context (pointer to a sph_panama_context)
void sph_panama ( 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).

Parameters:
cc the PANAMA context
data the input data
len the input data length (in bytes)
void sph_panama_close ( void *  cc,
void *  dst 
)

Terminate the current PANAMA computation and output the result into the provided buffer. The destination buffer must be wide enough to accomodate the result (32 bytes). The context is automatically reinitialized.

Parameters:
cc the PANAMA context
dst the destination buffer
