I believe these are Base-64 encoded output from
MD5. The $1$$ means something special, but I've
forgotten exactly what; in essence, though, it
says to use the new password scheme not the
original Unix one. The other 22 characters
represent 6 bits per character, and expand to 132
bits, of which only the first 128 are used.

Have fun cracking...
