I encrypted a 420GB tgz-archive under SuSE 10.1 Linux with:
gpg -o /USBDISK/anc.tgz.gpg -c --ciper-algo AES256 abc.tgz
a few days later I try to decrypt the file on the same computer via:
gpg -d <./abc.tgz.gpg >./abc_a.tgz
this decryption faild with errormessage:
:symkey enc packet: version 4, cipher 9, s2k 3, hash 2
salt 43b51101569918f8, count 96
gpg: AES256 encrypted data
:encrypted data packet:
gpg: encrypted with 1 passphrase
:literal data packet:
mode b (62), created 1193559656, name="abc.tgz",
raw data: unknown length
gpg: original file name='abc.tgz'
gpg: packet(14) with unknown version 26
gpg: WARNING: encrypted message has been manipulated!
gpg: packet(6) with unknown version 139
I repeated the decryption with different gpg versions (1.4.2, 2.0.4) on Linux
and Windows but always the same error.
I tryed --ignore-crc-error and --ignore-mdc-error but the decryption always
I found a thread discussing a similar decryption problem in the Gnupg-users
mail-archive from Oct 2005, but this thread focuses on the WinXP problem with
large files an did not help solving my problem.
Is there any possibility to recover my data?
