I think this functionality (mapping from long name to short PHYLIP-compatible and back) is in bioperl.  Would have to dig it up but I recall support being added many moons ago.

I think it is 10 characters (sequence starts at character 11), not that two characters is worth quibbling about, I just map the original names to hex numbers (which I think is likely to cover the number of sequences one can realistically align…), and then swap out the hex codes when I’ve finished with the alignment/tree etc, for what that is worth…

I only have a distance matrix derived from Mash and so I need a program to
make a tree from distances.  I do not think I can use RAxML or Mr. Bayes,
right?

The PHYLIP format can be used for distance matrices, and PHYLIP has various tools to build trees from them:

The MASH dist output file is VERY close to being a valid .PHY file (If taxnames <= 8 chars) but Brian Ondov seems unwilling to implement it within MASH - see my issue here: https://github.com/marbl/Mash/issues/9
