RE: Rsyncrypto using wrong gzip ?

[Jan A. <jan...@do...>]

Shachar,

Thanks for helping me.

I am using the MSI from sourceforge, the gzip is in the same directory as
rsyncrypto.

Here are the other answers:

A cannot decrypt files encrypted on B.
B can decrypt files encrypted on A.

The output is still the same, even with using the --gzip option on the
encrypt and decrypt command.

===== BEGIN COMMAND AND OUTPUT ======
"D:\test\RsynCrypto\RsynCrypto.exe" --gzip="D:\test\RsynCrypto\gzip.exe"
 "D:\Test\ClearFiles\testfile.pdf" "D:\Test\EncryptedFiles\testfile.pdf"
"D:\Test\keys\testfile.pdf" "D:\Test\Certificate\Cert.crt"

"D:\test\RsynCrypto\RsynCrypto.exe" -d --gzip="D:\test\RsynCrypto\gzip.exe"
"D:\Test\EncryptedFiles\testfile.pdf" "D:\Test\ClearFiles\testfile.pdf"
"D:\Test\keys\testfile.pdf" "D:\Test\Certificate\Cert.key"
Error in encrypted stream:

gzip: stdin: unexpected end of file
===== END COMMAND AND OUTPUT ======

Regards,

Jan

I'm missing the gzip file. Is this compiled from source or an 
installation from the MSI on sourceforge?

Doesn't seem likely.

Lets call the machine on which everything is working "A", and the other 
machine "B".

Can A decrypt files created on B? My guess would be "no"
Can B decrypt files created on A? My guess would be "yes"

Please try the same procedure on B again, but this time using the 
"--gzip" option to direct rsyncrypto to the specific gzip that came with 
the installation. Please let me know whether this makes any difference.
