.TH LIBRECRYPT_DECOMPOSE_CHAIN1 3 LIBRECRYPT
.SH NAME
librecrypt_decompose_chain1 - Replace algorithm link delimiters with null bytes
.SH SYNOPSIS
.nf
#include <librecrypt.h>
size_t \fBlibrecrypt_decompose_chain1\fP(char *\fIhash\fP);
.fi
.PP
Link with
.IR -lrecrypt .
.SH DESCRIPTION
The
.BR librecrypt_decompose_chain1 ()
function replaces each
.I LIBRECRYPT_ALGORITHM_LINK_DELIMITER
(which is
.BR \(aq>\(aq )
in
.I hash
with a null byte. This effectively decomposes
the string into one string per hash algorithm.
.PP
Unless already stripped out before input, the
last resulting string ends with the resulting
hash, if it was present in the input.
.PP
.I hash
must not be
.IR NULL .
.SH RETURN VALUES
The
.BR librecrypt_decompose_chain1 ()
function returns the number of chained hashes
(the same value as returned by
.BR librecrypt_chain_length (3)).
.SH ERRORS
The
.BR librecrypt_decompose_chain1 ()
function cannot fail.
.SH ATTRIBUTES
For an explanation of the terms used in this section, see
