You may try -v for verbose which will generate lots of output. eg. ./
jtrts.pl mschapv2 -v -v
The self test will only test against the vectors that you have provided in
fmt_tests[]. The test suite will test against the test vectors provided in
test directory. From the above report it looks like it can't crack some of
the test vectors. E.g guesses:1404 means it could guess 1404 out 1500
hashes correctly. Sometimes decreasing/Increasing the plaintext length may
help.
