T2P Authen Client Lib

How to Generate Toke Type H to use for Host to Host request

    //# Example 

    const t2plib = require('t2p-clientlib');
    const fs = require('fs')


    try {
        //###file client.key contains base64Ecode of Key that is provided to partner
        const clientKey = fs.readFileSync('client.key', 'utf8')

        //### Generate for using to request to get token Type C only (use by client mobile request header)
        var token = t2plib.preapare("requestbodydata",clientKey)
        console.log("<<tokenType H>>")
        console.log(token)
        console.log("\n")

        //### Generate for use with specific API URI only (use by Host to Host request header)
        var token = t2plib.preapare("requestbodydata",clientKey, '/wallet/some/api/function/')
        console.log("<<tokenType H>>")
        console.log(token)
        console.log("\n")

        //### Generate for use with any API (use by Host to Host request header)
        var token = t2plib.preapare("requestbodydata",clientKey, '')
        console.log("<<tokenType H>>")
        console.log(token)
        console.log("\n")

How to request for token type C for using on client (Mobile/Web)

    1. on the server generate token type H for host to host with fix uri input (/authen/v1/clientToken/generate) of the request token
    2. use token that recieve post to request token to url : https://test-api-authen.t2p.co.th/authen/v1/clientToken/generate

      (Prod : https://api-authen.t2p.co.th/authen/v1/clientToken/generate )

Decrypt the response from Host to Host request

    
    const t2plib = require('t2p-clientlib');
    const fs = require('fs')


    try {
        //file client.key contains base64Ecode of Key that is provided to partner
        const clientKey = fs.readFileSync('client.key', 'utf8')

        //Make Request to service then get the response as in API document

        decryptedText = t2plib.decryptData(encryptedText, clientKey)
    } catch (err) {
        console.error(err)
    }

Verify HashMac of input data using ClientKey

    
    const t2plib = require('t2p-clientlib');
    const fs = require('fs')


    try {
        //file client.key contains base64Ecode of Key that is provided to partner
        const clientKey = fs.readFileSync('client.key', 'utf8')

        #hashMac of input data
        var hash = '2819f93a1c5ba61028ba3fc01a50b3131e96795e6cb88c552759f4f001a66ee10583f63830774743d4d314d883fcebd2f59ffc6e78361807a0e3c0bfbf693464'
        var inputData = "somedata"

        var hashVerify = t2plib.verifyHashMac(inputData, hash, clientKey)
        console.log(hashVerify)
    } catch (err) {
        console.error(err)
    }

Generate HashMac of input data using ClientKey

    const t2plib = require('t2p-clientlib');
    const fs = require('fs')


    try {
        //file client.key contains base64Ecode of Key that is provided to partner
        const clientKey = fs.readFileSync('client.key', 'utf8')

        #hashMac of input data
        var inputData = "somedata"
        var hash = t2plib.generateHashMac(inputData, clientKey)
        console.log(hash)

    } catch (err) {
        console.error(err)
    }
