Packer for field 53 #16

Closed temper5 closed 6 years ago

temper5 commented 6 years ago

What the packer I can use for field 53? In specification this field consist from two sub fields f53a – lenght and f53b – data.

Field 53: Security Related Control Information Subfield 53a: Key Length Format n 2 Description In request and response messages this field contains length of Subfield 53b; Host should send Subfield 53a in the response message to POS terminal if terminal sent valid Subfields 53a and 53b in the request message to host. The key length in response message can be single length (8 byte), double length (16 bytes) or triple length (24 bytes) if key is in BCH representations. Subfield 53b: Key Information Format b 8/16/24 Description In request messages this subfield identifies maximum key length for key change transactions. Valid values are: 01 – single, 02 – double, 03 – triple key length. NOTE: The lengths have been converted to reflect their BCH representations. In response messages this subfield identifies security management information used in the current transaction or specifies security management information to be used in future transactions. This field is currently being used to supply new keys to devices for key change transactions. These keys can be either Single Des (8bytes) or Triple Des (16 or 24 bytes). NOTE: The lengths have been converted to reflect their BCH representations.

This is my "tmp" packager config for field 53:

'53': { length: 24, name: 'Security Related Control Information', type: 'b', alias: ''

In the example problem in response message where field53 not seems like not binary: cat ./800_TAK.txt - | nc localhost 2014

Please check packagers with names that start with ll

Like:

https://github.com/juks/SocketQueue/blob/master/lib/iso8583/lib/packer/ll-bin-n.js

juks commented 6 years ago

The default packager for EMV data is

'55': {
    length: 255,
    name:   'EMV Data',
    type:   'll-bin-char',
    alias:  ''
},

Thanks. I have try fixed-b. Why answer data in field 53 not in binary format (like field 1 - Bitmap)? Example: cat ./800_TAK.txt - | nc localhost 2014 0810" 9900000721154807123456170741083062098000B010000002

Unfortunately, some hardcode is still not eliminated. The projects is evaluation from custom to universal solution.

It is set here: https://github.com/juks/SocketQueue/blob/master/lib/iso8583/lib/iso8583.js#L37

temper5 commented 6 years ago

I think you only need to change packer in exports.pack for convert hex to bin.

I have change "fixed-b" like this:

exports.pack = function(data, packager) { var bytes = []; var str; for(var i=0; i< data.length-1; i+=2){ bytes.push(parseInt(data.substr(i, 2), 16)); } str = String.fromCharCode.apply(String, bytes); data = str; return { msg: data, };

And now ansewer is correct binary format.

Thanks. By default it assumes binary mask to come as a Buffer: https://github.com/juks/SocketQueue/blob/master/lib/iso8583/lib/iso8583.js#L164

Thank you. Close this issue.
