<div>I think you’re quite right that the existing ImageCacheManager code serves little purpose. What I propose here is a cryptographically stronger verification meant to protect against both deliberate modification <span style="font-family:Calibri,sans-serif;font-size:14px">by
an adversary, as well as accidental sources of disk corruption. If you like, I can deprecate the checksum-based verification code in the image cache as a part of this change. Feel free me to email me back or ping me on IRC (dane-fichter) in order to discuss
more.</span></div></div></blockquote><div><br></div><div>Thanks Dane, reviewed. I don't think the details are right yet, but I do think this is the way to go. I also think we need to entirely divorce this functionality from the image cache.</div><div><br></div><div>Matt</div></div>-- <br><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><span style="font-size:12.8px">Matthew Booth</span><br></div><div>Red Hat Engineering, Virtualisation Team</div><div><br></div><div>Phone: +442070094448 (UK)</div><div><br></div></div></div></div></div>
