Differing File Sizes & GPG Symmetric Decryption Failure After ~4G

[Packard, Matthew]

Werner,

    Thanks for your quick response - I compiled 1.2.2 (BTW had a weird 
issue with make and the ./tools/Makefile - complained about libcipher.a 
- I did a make clean and reran configure and it went OK). I'm in the 
process of decrypting the ~8G file right now (1.2.2 seems to decrypt a 
lot faster and with less CPU consumption - nice work), and I'll let you 
know how things turn out.

    But my new question is this - I searched through the man pages, the 
FAQ, Google, etc. and did not find any switches relating to the partial 
length headers option you mention. So, does that mean that GPG performs 
this under the hood, or do I need to supply a switch on 
encryption/decryption that will enable this? Also, is my current ~8G 
file no good after ~4G, since it doesn't look like I used partial length 
headers for the original encryption (not a big deal if the file is 
unusable, but it'd be nice to recover it)?

Thanks in advance,
Matthew Packard
