[Bug 1455990] Re: quassel-core generates an insecure certificate upon installation

[Felix Geyer]

As it's self signed certificate the signature hash algorithm doesn't matter much.
4096 bit seems a bit excessive, no?

Slightly offtopic:
Quassel stores the md5sum of certs the user has accepted. That's probably a bad idea.

Title:
  quassel-core generates an insecure certificate upon installation

Status in quassel package in Ubuntu:
  New

Bug description:
  After installation, quassel-core generates a 1024-bit certificate
  using the SHA1 hash.  Both of these are considered deprecated and
  somewhat insecure.  The attached patch updates the postinst script to
  generate a 4096-bit certificate using the SHA256 hash instead.

  The SHA256 certificate will not cause any compatibility problems
  because OpenSSL 1.0.0 and later support SHA256 certificates.  All
  supported versions of Ubuntu and Debian have at least 1.0.1 and the
  supported Windows and Mac builds of Quassel are additionally compiled
  with a recent enough version to support the SHA256 certificate.
