    Hi Clyde,
    
    Since no concerns have been raised, should we be expecting an updated syslog draft shortly?

    Hi,
    
    As part of the last few steps before again calling for last call for draft-ietf-netmod-syslog-model-14, we are adding certificate support to the signing-options container. RFC 5848: Signed Syslog Messages is the RFC that governs this section.
    
    The signing-options container resides within the remote action destination list section of the model. This means signing-options will be configurable for each remote destination.
    
    RFC 5848 supports four signature groups as defined in section 4.2.3 Signature Group and Signature Priority of the RFC:
    https://tools.ietf.org/html/rfc5848#section-4.2.3
    
    We are proposing to limit our support to Signature Group 0 which covers the case for administrators who want all messages of a syslog stream to be signed and Signature Blocks to be sent to a single destination.  We believe this case covers all deployment scenarios that are commonly encountered.  
    
    Support for Signature Groups 1 (each PRI value is associated with its own Signature Group), 2 (each Signature Group contains a range of PRI values), and 3 (Signature Groups are negotiated through a private arrangement) could be added to the model later through augmentation.
    
    Please let us know if you have any concerns about this.
    
    Thanks,
    
    Clyde
