+.SH NAME
+ykchalresp - Perform challenge-response operation with YubiKey
+.SH SYNOPSIS
+.B ykchalresp
+[\fI-1\fR | \fI-2\fR] [\fI-H\fR] [\fI-Y\fR] [\fI-N\fR] [\fI-x\fR] [\fI-v\fR] [\fI-h\fR]
+.\".SH DESCRIPTION
+.\" Add any additional description here
+.SH OPTIONS
+.PP
+Send a challenge to a YubiKey, and read the response.  The YubiKey can be configured
+with two different C/R modes -- the standard one is a 160 bits HMAC-SHA1, and the other
+is a YubiKey OTP mimicing mode, meaning two subsequent calls with the same challenge
+will result in different responses.
+.TP
+\fB\-1\fR
+send the challenge to slot 1.  This is the default.
+.TP
+\fB\-2\fR
+send the challenge to slot 2.
+.TP
+\fB\-H\fR
+send a 64 byte HMAC challenge.  This is the default.
+.TP
+\fB\-Y\fR
+send a 6 byte Yubico OTP challenge.
+.TP
+\fB\-N\fR
+non-blocking mode -- abort if the YubiKey is configured to require a key press before
+sending the response.
+.TP
+\fB\-x\fR
+challenge is hex encoded.
+.TP
+\fB\-v\fR
+enable verbose mode.
+
+.SH EXAMPLE
+The YubiKey challenge-response operation can be demonstrated using the
+\fBNIST PUB 198 A.2\fR test vector.
+.P
+First, program a YubiKey with the test vector :
+.HP
+.nf
+$ \fBykpersonalize -2 -ochal-resp -ochal-hmac -ohmac-lt64 -a 303132333435363738393a3b3c3d3e3f40414243\fR
+ ...
+Commit? (y/n) [n]: y
+$
+.fi
+.HP
+Now, send the NIST test challenge to the YubiKey and verify the result matches the
+expected :
+.HP
+.nf
+$ \fBykchalresp -2 'Sample #2'\fR
+0922d3405faa3d194f82a45830737d5cc6c75d24
