We discovered our problem. DTN2 uses a 40 character hex string. ION key file should contain a 20 byte ASCII key, not the hex equivalent of that as DTN2 expects. Thus, one can hexdump the 20 byte ION key file and use the hex value of that key in the DTN2 config. Still interested to know if anyone has run BAB interoperability with various DTN builds. --Will >-----Original Message----- >From: dtn-security-bounces@maillists.intel-research.net [mailto:dtn- >security-bounces@maillists.intel-research.net] On Behalf Of Ivancic, >William D.
