BASE64-based encryption coding auxiliary class Base64util

Achieve Results1) This auxiliary class is mainly used to facilitate the implementation of BASE64-based encryption coding. 2) Base64 is defined as: the Base64 Content transfer code is designed to describe any sequence of 8 bytes as a form that is not easy to be recognized directly. BASE64 encoding is typically found in e-mail messages, open an email to view its original information (you can view it by collecting and exporting the message in a text editor). Encryption is positive, but the purpose of encryption is not to send users a very secure email. This type of encryption is mainly "anti-gentleman against the villain."  That is, to reach a glance to completely see the content can be. 3) using BASE64 encoding is not only short, but also has the non-readability, that is, the encoded data will not be directly visible to the human eye.
