Signature Algorithms

Expert(s)

Unassigned

Reference

[RFC9162]

Note

This is a subset of the "TLS SignatureScheme" registry, limited to
those algorithms that are appropriate for CT.  A major advantage
of this is leveraging the expertise of the TLS Working Group and
its designated expert(s).
    

Note

The value 0x0403 appears twice.  While this may be confusing, it
is okay because the verification process is the same for both
algorithms, and the choice of which to use when generating a
signature is purely internal to the log server.

Note

The range 0x0000-0x00FF is reserved so that v1 SCTs are
distinguishable from v2 SCTs and other TransItem structures.

Log IDs

First Come First Served

Reference

[RFC9162]

Note

All OIDs in the range from 1.3.101.8192 to 1.3.101.16383 have been
set aside for Log IDs.  This is a limited resource of 8,192 OIDs,
each of which has an encoded length of 4 octets.
    

Note

The 1.3.101.80 arc has also been set aside for Log IDs.  This is an
unlimited resource, but only the 128 OIDs from 1.3.101.80.0 to
1.3.101.80.127 have an encoded length of only 4 octets.
