GPL code (unless that specific GPL code includes an exception for
OpenSSL - a habit that is growing more and more common). If OpenSSL's
licensing is a problem for you, consider using GnuTLS or yassl
instead.
GnuTLS http://www.gnutls.org/
(May be used for SSL/TLS support) Uses the LGPL[3] license. If this is
a problem for you, consider using OpenSSL instead. Also note that
GnuTLS itself depends on and uses other libs (libgcrypt and
libgpg-error) and they too are LGPL- or GPL-licensed.
yassl http://www.yassl.com/
(May be used for SSL/TLS support) Uses the GPL[1] license. If this is
a problem for you, consider using OpenSSL or GnuTLS instead.
NSS http://www.mozilla.org/projects/security/pki/nss/
(May be used for SSL/TLS support) Is covered by the MPL[4] license,
the GPL[1] license and the LGPL[3] license. You may choose to license
the code under MPL terms, GPL terms, or LGPL terms. These licenses
grant you different permissions and impose different obligations. You
should select the license that best meets your needs.
axTLS http://axtls.sourceforge.net/
(May be used for SSL/TLS support) Uses a Modified BSD-style license.
c-ares http://daniel.haxx.se/projects/c-ares/license.html
(Used for asynchronous name resolves) Uses an MIT license that is very
liberal and imposes no restrictions on any other library or part you
may link with.
zlib http://www.gzip.org/zlib/zlib_license.html
(Used for compressed Transfer-Encoding support) Uses an MIT-style
license that shouldn't collide with any other library.
krb4
While nothing in particular says that a Kerberos4 library must use any
particular license, the one I've tried and used successfully so far
(kth-krb4) is partly Original BSD-licensed with the announcement
clause. Some of the code in libcurl that is written to deal with
Kerberos4 is Modified BSD-licensed.
