Description Eric Christensen 2014-06-10 11:21:53 UTC
+++ This bug was initially created as a clone of Bug #1076390 +++

This is a tracking bug for Change: System-wide crypto policy
For more details, see: http://fedoraproject.org//wiki/Changes/CryptoPolicy

Unify the crypto policies used by different applications and libraries. That is allow
setting a consistent security level for crypto on all applications in a Fedora system. The implementation approach will be to initially modify SSL libraries to respect the policy and gradually adding more libraries and applications.

I wrote up something about this already (but can't find it) that can be used in the Release Notes and Security Guide.  As soon as I can lay my hands on it, again, I'll post it for review.

This is the text I'd like to use for the Release Notes and Security Guide if it looks good to the feature owner.

Let's not update the release notes and manual yet, as the details are not yet fixed. I expect these to be fixed by the end of next month.

I've updated the proposed text for the release notes.

<title>Crypto Policy</title>

<para>Beginning in Fedora 21, a system-wide crypto policy will be available for users to quickly setup the cryptographic options for their systems.  Users that must meet certain cryptographic standards can make the policy change in <filename>//etc/crypto-policies/config</filename>, and run update-crypto-policies. At this point applications that are utilize the default set of ciphers in the GnuTLS and OpenSSL libraries will follow the policy requirements.</para>

<para>The available options are: (1) LEGACY, which ensures compatibility with legacy systems - 64-bit security, (2) DEFAULT, a reasonable default for today's standards - 80-bit security, and (3) FUTURE, a conservative level that is believed to withstand any near-term future attacks -128-bit security.
These levels affect SSL/TLS settings, including elliptic curve, signature hash functions, and ciphersuites and key sizes.</para>

<para>Additional information on this new feature can be found on the <ulink url="https://fedoraproject.org/wiki/Changes/CryptoPolicy">CryptoPolicy Changes wiki page</ulink>.</para>

(In reply to Nikos Mavrogiannopoulos from comment #4)

Awesome, thanks!  I've added it to the Security Beat (https://fedoraproject.org/wiki/Documentation_Security_Beat) and it should be in the Release Notes for F21.
