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
