An issue with the configuration COM API has been resolved where OATH-HOTP configurations with Yubikey 2.2 caused unexpected HOTPs to be generated. No problems with pre-2.2 keys.<br /><br />From firmware version 2.2, the moving factor seed value can be set to an arbitrary value. The previous version of the configuration tool seeded this value with garbage/uninitialized data and as this field was not used prior to version 2.2, this issue was not noticed.<br /><br />An updated version of the COM API has been uploaded to our web at <!-- m --><a class="postlink" href="http://www.yubico.com/personalization-tool">http://www.yubico.com/personalization-tool</a><!-- m --><br /><br /><br />We were also asked to provide a test vector for OATH HOTP.
