I'm in the process right now of updating Visibroker, a widely-used commercial product, to support certificates with SHA-256 signatures. (I don't believe that's proprietary information, and anyone with a copy of Visibroker can easily discover it by trying to use such a certificate.) My guess is it's not the only one. That said, I think it makes sense to use SHA-256 in the tutorial. Anyone using it who runs into software that can't handle such certificates will get a useful bit of education in certificate signature algorithms. -- Michael Wojcik Technology Specialist, Micro Focus This message has been scanned for malware by Websense. www.websense.com :��I"Ϯ��r�m���� (����Z+�K�+����1���x��h����[�z�(����Z+���f�y�������f���h��)z{,���
