Truncation bug in the WOTS+C, FORS+C, XMMS and UXMMS implementations #3
Description
In WOTS+C, FORS+C, XMSS, and UXMMS cpp files, there is usage of sha256_add_to_ctx on the truncated message (sha256_add_to_ctx(ctx, message,N)), rather than hashing the whole message, and then truncating it (sha256_add_to_ctx(ctx, message, mlen)).
