Liferay 6.2 改造系列之二十四：修改liferay密码的加密方式

为了便于后期与Cas集成过程中使用数据库用户的方便，将liferay密码的加密方式改为SHA。

在/portal-master/portal-impl/src/portal.properties配置文件中，有如下配置：

#passwords.encryption.algorithm=BCRYPT/10
#passwords.encryption.algorithm=MD2
#passwords.encryption.algorithm=MD5
#passwords.encryption.algorithm=NONE
passwords.encryption.algorithm=PBKDF2WithHmacSHA1/160/128000
#passwords.encryption.algorithm=SHA
#passwords.encryption.algorithm=SHA-256
#passwords.encryption.algorithm=SHA-384
#passwords.encryption.algorithm=SSHA
#passwords.encryption.algorithm=UFC-CRYPT

改为：

#passwords.encryption.algorithm=BCRYPT/10
#passwords.encryption.algorithm=MD2
#passwords.encryption.algorithm=MD5
#passwords.encryption.algorithm=NONE
#passwords.encryption.algorithm=PBKDF2WithHmacSHA1/160/128000
passwords.encryption.algorithm=SHA
#passwords.encryption.algorithm=SHA-256
#passwords.encryption.algorithm=SHA-384
#passwords.encryption.algorithm=SSHA
#passwords.encryption.algorithm=UFC-CRYPT
