status = CRYPTERROR( [format] )

If "format" is omitted, or zero, then the value is returned as a numeric error number, or zero for "no error". If "format" is "1", then the value is returned as a string. Other values for "format" are undefined. (If ENCRYPT/DEcrypt fails, a null string -- "" -- is returned.)
