NOTICE (Updated October 13 2017): Because of security concerns with plaintext protocols, we still intend to disable the FTP protocol for downloads on this server (downloads would still be available over HTTP and HTTPS), but we will not be doing it on November 1, 2017, as previously announced here. We will be sharing our reasons and offering a chance to comment on this issue soon; watch this space for details. If you maintain scripts used to access over FTP, we strongly encourage you to change them to use HTTPS instead. --- Due to U.S. Export Regulations, all cryptographic software on this site is subject to the following legal notice: This site includes publicly available encryption source code which, together with object code resulting from the compiling of publicly available source code, may be exported from the United States under License Exception "TSU" pursuant to 15 C.F.R.
