Subject: Add aes-sha2 to permitted_enctypes and aes family
X-Git-Tag: krb5-1.15-beta1~10
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d1ec317288278d10ae34fde9b2414e4fca5c52dd;p=thirdparty%2Fkrb5.git

Add aes-sha2 to permitted_enctypes and aes family

Add the new aes-sha2 enctypes to the default value of
permitted_enctype, and to the enctypes implied by the "aes" family
when parsing enctype lists.
