  Landau-Khalatnikov-Fradkin transformations (LKFTs) yield the gauge dependence
of correlation functions within the class of linear covariant gauges. We derive
the LKFT for the quark propagator and explicitly evaluate it up to the two loop
level in the chiral limit. Although the number of diagrams to be evaluated is
significantly larger than with the conventional computational scheme, the
diagrams are simpler in nature, thereby leading to a considerably faster
evaluation of the gauge dependent part than naively expected. Finally, we also
resum the LKFT generated terms and compare our results with earlier work in the
literature.
