Notes

This page currently tracks the migration status of selected packages to SHA-256 as part of the StrongerHashes feature.

To Do

These packages use or refer to hashes from which we should migrate away. Being on this list does not yet mean the package will have to change: another manual check is necessary. You can see the known hash uses at http://people.redhat.com/mitr/hashes/found-hashes .

Configuration

Various packages support SHA-256, but their default configuration does not use it. Note that configuring the packages to use SHA-256 may prevent interoperability with systems that do not use SHA-256.

krb5

On the KDC, add

master_key_type = aes256-cts
supported_enctypes = aes256-cts:normal

to your realm configuration in kdc.conf.

On all machines add the following to the [libedefaults] section of krb5.conf:

default_tgs_enctypes = aes256-cts-hmac-sha1-96
default_tkt_enctypes = aes256-cts-hmac-sha1-96
permitted_enctypes = aes256-cts-hmac-sha1-96
kdc_req_checksum_type = 12
ap_req_checksum_type = 12
safe_checksum_type = 12

Done

These packages were already migrated. The "Notes" column should contain enough information to migrate from SHA-256 to a stronger hash in the future.
