RE: GPG Decryption fails for files > 1MB

[david.vazquez_landa]

Hello Werner, 

The files sent to us are already encoded using --armor. Funnily enough, only 
files larger than 1MB fail. Anything smaller can be decrypted without problems. 

Anyway, thanks for the hint.

Best Regards,

This might indicate a problem in your file transfer - make sure data is
not modified; i.e. the channel is 8 bit clean).  As a quick test you may
add the option --armor to the encryption command - this makes the
message larger but it will be plain ASCII.

I don't know whether you use a version of GPG build for Cygwin - I
suggest to use a native Windows version of GnuPG - and well; update to
a more recent version

I doubt that.  If you need support, you may want to checkout the service
directory at gnupg.org.



Salam-Shalom,

GPG Decryption fails for files > 1MB

[david.vazquez_landa]

Hello list,

 

We have an issue with one of our users. When he sends encrypted messages larger 
than ~1 MB, we get these errors:

 

8218 - PGP decryption error - gpg: encrypted with RSA key, ID CD5AA2E4

gpg: encrypted with 2048-bit RSA key, ID B44D925D, created 2006-03-29

  "Mehdi Rahman "

gpg: encrypted with 2048-bit RSA key, ID 4E9BF326, created 2010-03-16

  "Mehdi Rahman "

gpg: encrypted with 2048-bit ELG-E key, ID 044C8E09, created 2008-04-04

  "EXDI_STC (EXDI PGP key for STC) "

gpg: [don't know]: invalid packet (ctb=27)

gpg: [don't know]: invalid packet (ctb=0d)

gpg: mdc_packet with invalid encoding

gpg: decryption failed: invalid packet

gpg: [don't know]: invalid packet (ctb=0a)

gpg: block_filter: pending bytes!

gpg: no valid OpenPGP data found.

 

This is the output of gpg.exe –version:

 

$ /cygdrive/d/GNU/GnuPG/gpg.exe --version

gpg (GnuPG) 1.4.8
