enctempfile

enctempfile allows you to transparently encrypt temporary files. These files are buffered in memory and broken down into blocks, and each individual block is written to a temporary file and encrypted using Fernet encryption, with temporary keys unique to each block.

Usage

import enctempfile

with enctempfile.TemporaryFile() as fp:

    fp.write(b"hello")
    fp.flush()

    fp.seek(0)

    print(fp.read())

All temporary files are currently mode wb+, text mode is not supported. Block size can be specified to the constructor using the block_size argument.
