Original GitHub issue: https://github.com/s3fs-fuse/s3fs-fuse/issues/388

I have been working with SSE-C capabilities of 's3fs', and after reading through, what I found out is a custom key can be specified at the time of mounting. What if individual files in a single bucket are encrypted with different keys. Is there a specific way to mount a bucket simply, and make download/fetch requests for a particular file with a particular key ?

Let me know, in case the problem statement is not clear.

EDIT
Additionally, just now I discovered that reading encrypted file is not working even after mounting with custom key.

Hoping so that the following command is correct for SSE-C

sudo s3fs my-own-bucket /var/s3 -o allow_other -o use_sse=custom:/etc/mykey

I would also like to add the fact the file upload(encrypt)/download(decrypt) is working fine through SDK.

EDIT
I realized that there is a 'load_sse_c' option. But I am not able to get it working. As, the syntax for it's seems to be unclear.
Tried -o load_sse_c=/etc/mykey and -o load_sse_c /etc/mykey , yet suffers from syntactical errors.
