#define SPH_SIZE_md4 128 |
Output size (in bits) for MD4.
void sph_md4_init | ( | void * | cc | ) |
Initialize a MD4 context. This process performs no memory allocation.
cc | the MD4 context (pointer to a sph_md4_context ) |
void sph_md4 | ( | 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).
cc | the MD4 context | |
data | the input data | |
len | the input data length (in bytes) |
void sph_md4_close | ( | void * | cc, | |
void * | dst | |||
) |
Terminate the current MD4 computation and output the result into the provided buffer. The destination buffer must be wide enough to accomodate the result (16 bytes). The context is automatically reinitialized.
cc | the MD4 context | |
dst | the destination buffer |
Apply the MD4 compression function on the provided data. The msg
parameter contains the 16 32-bit input blocks, as numerical values (hence after the little-endian decoding). The val
parameter contains the 4 32-bit input blocks for the compression function; the output is written in place in this array.
msg | the message block (16 values) | |
val | the function 128-bit input and output |
