It is.

This is a decision we made when moving to sha512, because we wanted the
file to contain the used hash function. (for the future, when we
invariably move again to a new hash function)

We were starting to talk about our own format, then someone (I think it
might have been Peter?) told me about the BSD tagged format, and we
just went with that.

Not only can it parse it, it can also generate it:

    $ sha512sum --tag some-file
    SHA512 (some-file) = ...
