This product includes software developed at
The Apache Software Foundation (http://www.apache.org/).

The implementation for org.apache.shiro.util.SoftHashMap is based
on initial ideas from Dr. Heinz Kabutz's publicly posted version
available at http://www.javaspecialists.eu/archive/Issue015.html,
with continued modifications.

The implementation of Radix64 aka BcryptBase64 (OpenBSD BCrypt’s Base64) was copied
from https://github.com/patrickfav/bcrypt.

Certain parts (StringUtils, IpAddressMatcher, etc.) of the source
code for this  product was copied for simplicity and to reduce
dependencies  from the source code developed by the Spring Framework
Project  (http://www.springframework.org).
