Loading Saved ciphertext and decrypting it

Library Questions
1

Hello,

I am using Pyfhel to encrypt an integer and then saving it to a file. When I load the file in the same execution context, I am able to decrypt and get the expected result. But when I use a previously stored file to load the PyCtxt, the decryption result is random. Could you help me understand what could be going wrong?

Below are samples post decryption.

Thanks
Priyanka

Result with a temp file saved in the same execution context
#. Decrypting result:
int1: decrypt(ctxt1) = [98 0 0 … 0 0 0]

Result with previously saved ciphertext file
#. Decrypting result:
int1: decrypt(ctxt1) = [ 28041 17905 21111 … -2426 6702 -23364]

You might have better luck reaching out to the Pyfhel team. It could be because of a variety of reasons - if you can recreate the issue directly in OpenFHE then we will be better equipped to help.

Thanks @iquah.

Raised an issue on Pyfhel Github. Hopefully I will hear back soon. I might leave this post open for now, in case anyone else is aware of anything. Also in the meantime, I will see if I can replicate the issue in openFHE.
