Excerpt from upstream's README:
The library is distributed under the terms of the GNU Lesser
General Public License (LGPL); see the file COPYING.LIB for the
actual terms. The helper programs (gcryptrnd and getrandom) as
well as the documentation are distributed under the terms of the
GNU General Public License (GPL); see the file COPYING for teh
actual terms.
This library used to be available under the GPL - this was changed
with version 1.1.7 with the rationale that there are now many free
crypto libraries available and many of them come with capabilities
similar to Libcrypt. We decided that to foster the use of
cryptography in Free Software an LGPLed library would make more
sense because it avoids problems due to license incompatibilities
between some Free Software licenses and the GPL.
Please note that in many cases it is better for a library to be
licensed under the GPL, so that it provides an advantage for free
software projects. The Lesser GPL is so named because it does
less to protect the freedom of the users of the code that it
covers. See http://www.gnu.org/philosophy/why-not-lgpl.html for
more explanation.
