I got the following messages when I tried to decrypt a file.gpg with
the size 4,920,412,393 bytes using gpg version 1.4.2, official Windows version:
>gpg -vv -o file --decrypt file.gpg
:symkey enc packet: version 4, cipher 9, s2k 3, hash 2
salt 5088796db832388a, count 96
gpg: AES256 encrypted data
:encrypted data packet:
gpg: encrypted with 1 passphrase
:compressed packet: algo=1
:literal data packet:
mode b (62), created 1126887210, name="file",
raw data: 614055611 bytes
gpg: original file name='file'
gpg: [don't know]: invalid packet (ctb=7e)
gpg: [don't know]: invalid packet (ctb=32)
gpg: WARNING: encrypted message has been manipulated!
:unknown packet: type 59, length 35

gpg: [don't know]: invalid packet (ctb=2c)
GPG failed when the output file has a size of 614,055,611 bytes. I
noticed this is exactly the number of bytes shown by "raw data:" in
the above messages. Is this a flaw in GPG? It's hard to believe GPG
would have a serious flaw like this, because there was absolutely no
error message when I encrypted the file, and now GPG is unable to
decrypt the file to its ooriginal size?
Can anyone please help me recover my data! Thanks.
