#define SPH_SIZE_md5 128 |
Output size (in bits) for MD4.
void sph_md5_init | ( | void * | cc | ) |
Initialize a MD5 context. This process performs no memory allocation.
cc | the MD5 context (pointer to a sph_md5_context ) |
void sph_md5 | ( | 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 MD5 context | |
data | the input data | |
len | the input data length (in bytes) |
void sph_md5_close | ( | void * | cc, | |
void * | dst | |||
) |
Terminate the current MD5 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 MD5 context | |
dst | the destination buffer |
void sph_md5_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 (16 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.
cc | the MD5 context | |
ub | the extra bits | |
n | the number of extra bits (0 to 7) | |
dst | the destination buffer |
Apply the MD5 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 |
