regarding compution of v5 signatures we have the following lines
in section 5.2.4 of the current draft RFC 4880bis-06:
"a eight-octet big-endian number that is the length of the
hashed data from the Signature packet stopping right before the
0x05, 0xff octets."
I am wondering why a number of eight-octet size is used here. The
biggest field
I don't know about this.
, AFAIS i.e. the hashed subpacket data area, is limited
by the included two-octet hashed subpacket length. So why 64 bit?
Actually, the MPIs can be larger. They take up the remainder of the
packet. In practice, the MPIs are just a few kilobytes today, but
with post-quantum crypto, they could get very large.
