Currently, DKIM is published under RFC 6376. DKIM has gone through various updates and modifications through the years. The most recent versions include RFC 8301 (issued in January 2018) and RFC 8463 (issued in September 2018) both assembling some key protocol improvements. Modifications include a larger key size for enhanced security (1024-4096) and shorter public keys that can be easily published on your DNS.
