---+ RFC proxy and SHA-2 signature support in WLCG middleware

---++ Introduction

IGTF would like CAs to move from SHA-1 to SHA-2 signatures ASAP,
to anticipate concerns about the long-term safety of the former.

   *  See https://twiki.grid.iu.edu/bin/view/Security/HashAlgorithms

For WLCG this implies using RFC proxies instead of the
Globus legacy proxies in use today.

   * See [[https://indico.cern.ch/getFile.py/access?sessionId=4&resId=3&materialId=0&confId=155064][Jan GDB presentation]]
   for detailed explanation

Updates on the state of affairs are regularly presented in GDB meetings:

---++ Phases and milestones

---+++ 1. Deployment of SW supporting RFC proxies

   * Proxy usage:
      * Legacy
      * RFC only in special tests
      * SHA-2 only in special tests
   * SW supports:
      * Legacy
      * RFC maybe
      * SHA-2 maybe
   * Milestone:
      * All deployed SW supports RFC proxies
   * Additional goal:
      * All deployed SW supports SHA-2, except dCache and !BeStMan

---+++ 2. Switch to RFC proxies

   * There should be no issues with that by this time

---+++ 3. Upgrade dCache and !BeStMan

   * Proxy usage:
      * RFC
      * SHA-2 only in special tests
   * SW supports:
      * RFC
      * SHA-2 maybe
   * Milestone:
      * All deployed SW supports SHA-2

---+++ 4. Introduce SHA-2 CAs

   * Plan B ?
      * Best avoided!
