+The
+.Nm cryb_md2
+family of functions implements the MD2 message digest algorithm as
+described in RFC 1319.
+.Pp
+The
+.Fn cryb_md2_init
+function initializes the context structure pointed to by

+.Pp
+The

+function hashes the next

+pointer into the given hash context.
+.Pp
+The
+.Fn cryb_md2_final
+function finalizes the computation and writes the resulting message
+digest to the caller-provided buffer pointed to by
+.Va digest ,
+which must be at least
+.Dv MD2_DIGEST_LEN
+bytes long.
+It is the caller's responsibility to dispose of the context structure
+after calling
+.Fn cryb_md2_final .
+.Pp
+The
+.Fn cryb_md2_complete
+function is a shortcut to calling
+.Fn cryb_md2_init ,
+.Fn cryb_md2_update ,
+and
+.Fn cryb_md2_final
+when the entire message is available up front in a single contiguous

+.Sh IMPLEMENTATION NOTES
+The
+.In cryb/md2.h
+header provides macros which allows these functions and the context
+type to be referred to without their
+.Dq Li cryb_
+prefix.
+.Pp
+The MD2 message digest algorithm has been proven to be vulnerable to
+collision attacks and should not be used for cryptographic purposes.
