.Sh DESCRIPTION
The
.Fn krb5_digest_alloc
function allocatates the
.Fa digest
structure.  The structure should be freed with
.Fn krb5_digest_free
when it is no longer being used.
.Pp
.Fn krb5_digest_alloc
returns 0 to indicate success.
Otherwise an kerberos code is returned and the pointer that
.Fa digest
points to is set to
.Dv NULL .
.Pp
.Fn krb5_digest_free
free the structure
.Fa digest .
