We have an app which uses crypto++ 5.0 to
encrypt/decrypt text files across 3 platforms - W2K,
Solaris 9 and AIX.
I am now trying to add Linux (Red Hat) to this list,
but find I cannot decrypt anything encrypted on the
other platforms. These other platforms cannot decrypt
the files I can successfully encrypt/decrypt on Linux.
I am using GNU tools.
The calls to crypto++ look like this (we are using the
default encryption - the point being the app code and
calls do not change between platforms):
********code frag starts********
void EsCrypt::EsEncryptFile(const char *in, const char
*out, const char *passPhrase)
{
//cout << "inside EncryptFile" << endl;
FileSource f(in, true, new
DefaultEncryptorWithMAC(passPhrase, new
FileSink(out)));
}
void EsCrypt::EsDecryptFile(const char *in, const char
*out, const char *passPhrase)
{
FileSource f(in, true, new
DefaultDecryptorWithMAC(passPhrase, new
FileSink(out)));
}
*********code frag ends*******
I am building the Linux version with g++ v 3.2.2 (on
Solaris I use g++ 3.2.3).
The Linux kernel release is 2.4.20-8
The same file encrypted under Linux and Solaris is
exactly the same size. However, when opened in an
editor the contents are different.
I've tried to defining __INTEL__ (mentioned in
congig.h) but this doesn't seem to make any
difference.
Perhaps there is some other setting? Has anyone else
come across this problem?
Thanks
