distinguishing gnupg and pgp messages encrypted to rsa v4 keys

[vedaal at hush.com]

]if someone uses compression algo 1,
]and encrypts a message to an rsa v4 key,
]using a 256 bit algorithm,

]{and leaves out the version line ;-) }

]is it possible to determine that the message was encrypted using gnupg
]and not pgp 8?

sorry, my mistake ;-((

i was working with rsav4 keys in ckt,
and assumed that it would be the same as in pgp 8  ;-(


it is trivial to tell the difference just from the ascii armor :
ascii armored encrypted messages in pgp 8, begin with 
Q...
in gnupg (and ckt) they begin with
H...

in gpg list packets,
all ascii armored pgp encryptions (of text messages)have
"literal data packet:
	mode t "
while gnupg encryptions have 'mode b'

when encrypting (a text message) to a rsa v3 key using idea,
gnupg also uses 'mode t'

i can't find any 'list packet' differences between gnupg and pgp encryptions
of text to a v3 key using idea

are there any?

tia,

vedaal
