723146 - Make nsCheckSummedxxxStream usable for outside consumers

Status: NEW

(Core :: Networking: File, defect, P5)

Description

[Gian-Carlo Pascutto [:gcp]]

Bug 673470 introduces nsCheckSummedOutputStream for file integrity checking. Might be useful for other parts of Firefox and there are some obvious improvements that can be made:

a) Make it wrap nsSafeOutputStream instead of deriving from it. Would allow it to avoid peeking into nsSafeOutputStream.
b) Add nsCheckSummedInputStream, combining nsBufferedInputStream (to avoid reading a checksummed file twice) and checksum verification.
c) Give it an IDL, IID and contractid once it's cleaned up.
