◆ sph_jh224()

void sph_jh224 ( 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
ccthe JH-224 context
datathe input data
lenthe input data length (in bytes)

Definition at line 1011 of file jh.c.

◆ sph_jh224_addbits_and_close()

void sph_jh224_addbits_and_close ( void *  cc,
unsigned  ub,
unsigned  n,
void *  dst 
)

Add a few additional bits (0 to 7) to the current computation, then terminate it and output the result in the provided buffer, which must be wide enough to accomodate the result (28 bytes). If bit number i in ub has value 2^i, then the extra bits are those numbered 7 downto 8-n (this is the big-endian convention at the byte level). The context is automatically reinitialized.

Parameters
ccthe JH-224 context
ubthe extra bits
nthe number of extra bits (0 to 7)
dstthe destination buffer

Definition at line 1025 of file jh.c.

◆ sph_jh224_close()

void sph_jh224_close ( void *  cc,
void *  dst 
)

Terminate the current JH-224 computation and output the result into the provided buffer. The destination buffer must be wide enough to accomodate the result (28 bytes). The context is automatically reinitialized.

Parameters
ccthe JH-224 context
dstthe destination buffer

Definition at line 1018 of file jh.c.

◆ sph_jh224_init()

void sph_jh224_init ( void *  cc)

Initialize a JH-224 context. This process performs no memory allocation.

Parameters

Definition at line 1004 of file jh.c.

◆ sph_jh256()

void sph_jh256 ( void *  cc,
const void *  data,
