Apr 10 '21 at 8:23 comment added AndiCover @poncho Ah you mean if I do not store the seed in the LMOTS keys I could decrease the size by about 1GB? I will consider that in my implementation.
Apr 9 '21 at 12:55 comment added poncho Well, when you say that LMS_SHA256_M32_H25 & LMOTS_SHA256_N32_W1 requires a 1.9GB private key, well, it can be implemented with a considerably shorter private key than that...
Apr 9 '21 at 5:09 comment added AndiCover @poncho That's what I wanted to say or did I understand you wrong?
Apr 8 '21 at 21:45 comment added poncho For the LMS private key, we can use the same RNG trick to use a single n byte seed to determine all the private OTS values; appendix A of the RFC gives one suggested way.
