It doesn't matter. From RFC4034 (Resource Records for the DNS Security
Extensions), section 2.2 (The DNSKEY RR Presentation Format):

  The Public Key field MUST be represented as a Base64 encoding of the
  Public Key.  Whitespace is allowed within the Base64 text.  For a
  definition of Base64 encoding, see [RFC 3548].
