Problems with file upload using HTTPS post

I have a script that connects to a server and posts a file using multipart form data. When I post to the server using HTTP the post works correctly. When I post using HTTPS, the file is reporting the wrong size when it reaches the server. The file contains raw binary data.

File size using HTTP is 800032 sent and 800032 received.

File size using HTTPS is 800032 sent and 800045 received.

The only difference is using HTTPS versus HTTP.

Any ideas?

Thank you,
