+.TH LIBKECCAK_BEHEX_LOWER 3 LIBKECCAK-%VERSION%
+.SH NAME
+libkeccak_behex_lower - Converts a binary hashsum to lowercase hexadecimal
+.SH SYNOPSIS
+.LP
+.nf
+#include <libkeccak.h>
+.P
+void libkeccak_behex_lower(char *restrict \fIoutput\fP,
+ const char *restrict \fIhashsum\fP,
+ size_t \fIn\fP);
+.fi
+.P
+Link with \fI-lkeccak\fP.
+.SH DESCRIPTION
+The
+.BR libkeccak_behex_lower ()
+function
+converts a binary hashsum, stored in \fIhashsum\fP,
+to lowercase hexadecimal, and stores the
+hexadecimal representation in \fIoutput\fP.
+.PP
+\fIoutput\fP will be terminated by a NUL-character.
+.PP
+The \fIn\fP parameter specifies the number of bytes
+the binary hashsum is comprised. \fIoutput\fP needs
+an allocation size of (2 * \fIn\fP + 1).
+.SH RETURN VALUES
+The
+.BR libkeccak_behex_lower ()
+function does return any value.
+.SH ERRORS
+The
+.BR libkeccak_behex_lower ()
+function cannot fail.

+.TH LIBKECCAK_UNHEX 3 LIBKECCAK-%VERSION%
+.SH NAME
+libkeccak_unhex - Converts a hexadecimal hashsum to binary
+.SH SYNOPSIS
+.LP
+.nf
+#include <libkeccak.h>
+.P
+void libkeccak_unhex(char *restrict \fIoutput\fP,
+ const char *restrict \fIhashsum\fP);
+.fi
+.P
+Link with \fI-lkeccak\fP.
+.SH DESCRIPTION
+The
+.BR libkeccak_unhex ()
+function
+converts a hexadecimal hashsum, stored in \fIhashsum\fP,
+to binary, and stores the binary representation in
+\fIoutput\fP.
+.PP
+\fIhashsum\fP must be terminated by a NUL-character.
+It may be in either lowercase or uppercase, or a mixture
+thereof. \fIoutput\fP will not be terminated.
+.PP
+(\fBstrlen\fP(\fIhashsum\fP) / 2) bytes will be written to
+the beginning of \fIoutput\fP. It should therefore have
+an allocation of at least that number of bytes.
+.SH RETURN VALUES
+The
+.BR libkeccak_unhex ()
+function does return any value.
+.SH ERRORS
+The
+.BR libkeccak_unhex ()
+function cannot fail.
+.SH NOTES
+\fIhashsum\fP must have an even number of digits
+(characters excluding the terminating NUL-character.)
