Testing versions

Occasionally Mike will make testing (ie non-release) versions of Stunnel available. These are available in the TESTING directory at stunnel.mirt.net. These versions are not maintained on stunnel.org because mirroring is currently a somewhat-manual process.

The Stunnel software package does not contain any cryptography itself, however please remember that import and/or export of cryptographic software, code providing hooks to cryptographic algorithms, and discussion about cryptography is illegal in some countries. It is imperative for you to know your local laws governing cryptography. We're not liable for anything you do that violates your local laws.
