Function Documentation
void sph_bmw224_init |
( |
void * |
cc |
) |
|
Initialize a BMW-224 context. This process performs no memory allocation.
- Parameters:
-
| cc | the BMW-224 context (pointer to a sph_bmw224_context ) |
void sph_bmw224 |
( |
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 BMW-224 context |
| data | the input data |
| len | the input data length (in bytes) |
void sph_bmw224_close |
( |
void * |
cc, |
|
|
void * |
dst | |
|
) |
| | |
Terminate the current BMW-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:
-
| cc | the BMW-224 context |
| dst | the destination buffer |
void sph_bmw224_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:
-
| cc | the BMW-224 context |
| ub | the extra bits |
| n | the number of extra bits (0 to 7) |
| dst | the destination buffer |
void sph_bmw256_init |
( |
void * |
cc |
) |
|
Initialize a BMW-256 context. This process performs no memory allocation.
- Parameters:
-
| cc | the BMW-256 context (pointer to a sph_bmw256_context ) |
void sph_bmw256 |
( |
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 BMW-256 context |
| data | the input data |
| len | the input data length (in bytes) |
void sph_bmw256_close |
( |
void * |
cc, |
|
|
void * |
dst | |
|
) |
| | |
Terminate the current BMW-256 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 BMW-256 context |
| dst | the destination buffer |
void sph_bmw256_addbits_and_close |
( |
void * |
cc, |

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.
