An fs module stand-in for reading and writing encrypted files
$ npm install efs
efs attempts to be as similar to
fs as possible. The one place where
it differs is in how it needs to be required.
var efs = ;// encrypt and write fileefs;// decrypt and read fileefs;
There's only one API method in
efs that differs from Node's
module. Please see Node's fs docs
for how to use all the other methods.
efs module with the given encryption algorithm and

efs.openonly supports opening a file for writing.
efs.readSyncis not supported.
efs.writeis not supported.
efs.truncateSyncare not supported.
