cryptlib is licensed under the Sleepycat license with a SaaS restriction:
“Note that decoupling the software from the user, for example by running
in a SaaS configuration, does not exempt you from these requirements.”
(Full text attached.)
This was not part of the original Sleepycat license, so a new license
tag is required.
Maybe this license is not even free; this additional clause seems to be
a restriction on use. But perhaps it is not so different from the AGPL.
