+This library is a simple wrapper providing a convenient reentrant interface for
+the bcrypt password hashing algorithm implementation as provided by Solar
+Designer at http://www.openwall.com/crypt/. An exact copy of that source code
+is included with minor Makefile modifications in the crypt_blowfish
+subdirectory.
+
+The provided C interface is inspired in the bcrypt Python module that can be
+found at http://code.google.com/p/py-bcrypt/, and consists of a function to
+generate salts with the characteristic work factor parameter, and one to
+generate password hashes, which in turn is also used to verify passwords.
+
+All this code is released to the public domain.
