.Sh LIBRARY

.Ft void
.Fn cryb_md2_init "cryb_md2_ctx *context"

.Ft void
.Fn cryb_md2_complete "const void *data" "size_t len" "uint8_t *digest"
.Sh DESCRIPTION
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
.Va context .
It is the caller's responsibility to allocate this structure.
.Pp
The
.Fn cryb_md2_update
function hashes the next
.Va len
bytes of data pointed to by the
.Va data
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
buffer.
.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.
