Stunnel Source Code

Files with a .asc extension are detached PGP signatures. As of Stunnel version 3.8, Michal has begun PGP signing the Stunnel tarballs and executables. You can get a copy of his PGP public key on his home page. PGP keys for Brian Hatch can be found here, and the key used for Stunnel-3.x branch is available here.

If you're having trouble compiling, read the Compilation Problems section of the FAQ. You may also wish to visit the patches section of this web page to see if there's anything that strikes your fancy.

Note that the .tgz files are gzipped tar archives. Some browsers may be 'helpful' and ungzip them for you, leaving a tar archive with .tgz suffix. Use the file command on the source if you're having trouble determining what filetype it is.

The most recent stable Stunnel version is flagged with a red asterisk (*). You may want to check out the ChangeLog file to see what differences exist between versions.
