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.
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.
