You can find this in the Makefile.in file:

# Which message-digest algorithm do you want to use?
#
# MD5 is the default and highly recommended because it is stronger. Sites
# migrating from Bellcore S/Key v1 might want to use MD4 for compatibility
# reasons. Support for MD4 will be removed in a future version of OPIE.
MDX=5
#MDX=4

Several of the changes  were made to sync  with  the latest OTP  specs from
IETF. It won't be really stable till the IETF put forth the RFC.
