CPay encryption and decryption through RSA certificate key files or text.

The following methods for RSA encryption and decryption :

cPayGetEncryptionDataFromKeyFile(input_data, key_filepath, calback);

cPayGetEncryptionDataFromKeyText(input_data, key_txt, calback);

cPayGetDecryptionDataFromKeyFile(input_data, key_filepath, calback);

cPayGetDecryptionDataFromKeyText(input_data, key_txt, calback);

Example Code:

var cpayEncDec = require('cpay-enc-dec');

var json = {
    "name" : "cpay"
}

var enc_rslts: any;

// convert json/string data to rsa encrypted format with public key file
cpayEncDec.cPayGetEncryptionDataFromKeyFile(json, '/certificates/public.key', (encrpt_err, encrpt_res)=>{
    if(encrpt_err){
        console.log(encrpt_res);
        //with error do something
    }
    else{
        console.log(encrpt_res);
        enc_rslts = encrpt_res;
        //with encrypted data do something
    }
})


// convert rsa encrypted data to decrypted json/string data format with private key file
cpayEncDec.cPayGetDecryptionDataFromKeyFile(enc_rslts, '/certificates/private.key', (dcrpt_err, dcrpt_res)=>{
    if(dcrpt_err){
        console.log(dcrpt_res);
        //with error do something
    }
    else{
        console.log(dcrpt_res);
        //with decrypted data do something
    }
})

var public_key_txt = "IgUMIRSetSr2XU+E5lUvYe2y0yEgHjAkb82++B1G/yw6o0YCsnNg8GhQbSHKTHLanJvdLYv5W5kmFCdQCWyFtmc45MeT1MTwkPUav1xhSzEu5UcErONggQLIhDnAjRNuxbo5p4Hvw3R/zOgnNtE";
