Hi there, RSASHA I wanted to add DS records for reverse lookup here. I signed the zone files and copied the dsset stuff into the appropriate text box. When importing the DS record, the following error message is shown: RSA/SHA-256 does not support algorithm SHA-1 At first I thought that the zonesigner tool used SHA-1 to create the key, but after issuing zonesingner with the option "-algorithm RSASHA256", the same error message keeps showing up... Any ideas what could be wrong? (Sorry for not providing more detailed information, but I don't currently know what could be of interest. If there's anything needed to better answer my question, please just let me know.) Best, Thomas
