For the record, the "no military use" clause only applies to the generic
OSI licence. It was that restriction that prevented OCB's inclusion in
OpenSSL for some while. The OpenSSL implementation uses a different licence:
https://www.openssl.org/docs/misc/OCB-patent-grant-OpenSSL.pdf

This is not encumbered by the no military use restriction.
