|
The

|
.Fn cryb_sha224_init
|

|
function initializes the context structure pointed to by
|

.Va context .
|

It is the caller's responsibility to allocate this structure.
|

|
.Pp
|

The

.Fn cryb_sha224_update

|
.Pp
|

|
The

.Fn cryb_sha224_final

|
function finalizes the computation and writes the resulting message
|

|
digest to the caller-provided buffer pointed to by

which must be at least

It is the caller's responsibility to dispose of the context structure

after calling

.Pp
|

|
The
