getvalue is required by the checksum interface , but we can return only one of the three values . we return the crc32 value , since that 's the one which is guaranteed to be available . concode_field_sep CRC32 _crc32 concode_elem_sep MessageDigest _md5 concode_elem_sep MessageDigest _sha1 concode_elem_sep long _nByte concode_field_sep String getMD5 concode_elem_sep String padLeadingZeroes concode_elem_sep void reset concode_elem_sep void update concode_elem_sep void update concode_elem_sep void update concode_elem_sep void update concode_elem_sep String getCRC32 concode_elem_sep String getSHA1
