用MD5校验器
若用命令行运行:
OPTION switches:
-B Base64 encoded output, instead of default hex format
-b Bare output, no path headers
-e Exit immediately; don't pause before returning
-n No percent done indicator
-p Pause before returning (incompatible with -e)
-s Display statistics at end (hashing speed)
-u Mimic output of UNIX md5 command (implies -b, -n)
