> {{Base64.encodeBase64String(value)}} encodes binary data using the base64 algorithm into 76 character blocks separated by CRLF.
> In fs shell, xattrs display like:
> {code}
> # file: /user
> user.a1=0sMTIz
> user.a2=0sMTIzNDU2
> user.a3=0sMTIzNDU2
> {code}
> We don't need multiple line and CRLF for xattr value, and we can use:
> {code}
> Base64 base64 = new Base64(0);
> base64.encodeToString(value);
> {code}
