Crypto required but not loaded

[fusiodarts]

• Node.js Version: v7.10.0
• OS: Ubuntu 16.04
• Module (and version) (if relevant): crypto

Hi,

I require crypto as 'var crypto = require("crypto")', but it doesn't find the crypto functions.
I have installed the crypto module, version 0.0.3, the latest.

So, I don't know where is the problem.
I am using a NodeJS project to implement a payment gateway, using crypto but it doesn't work.
The test in this module (in node_modules folder) works fine, but in an external controller instantiating the library not.

Thanks.

crypto is an internal Node.js module, you do not need to install it. You can uninstall the external one so it does not shadow the internal module and then just use var crypto = require("crypto").

[fusiodarts]

Yes yes it is ok, but the problem is that in the test in the payment gateway project inside node_modules, it works fine, but when we call the library from an external controller, it doesn't find crypto.

We have tried to install the crypto module because it didn't work as internal NodeJS, but we receive the same result.
We have already uninstalled the crypto external module.

Is there any chance that you can be more specific? “it doesn't find the crypto functions” doesn’t tell so terribly much…

[fusiodarts]

I mean that this line don't require "crypto" if I call it from an external controller.
I need it because in the external controller where I am instantiating the library I need to use the createCipheriv function.

Can you share any code to reproduce the problem?

In the external controller I am instantiating var Sermepa = require('sermepa').
It instantiate the library, which requires "crypto"

[tniessen]

"In the external controller", are you referring to client-side code within a browser or is this within your node process?

[fusiodarts]

@gibfahn yes, it is mine. I have wrote in the incorrect platform, so the owner redirect me to this platform, sorry.

[fusiodarts]

@tniessen yes, a controller inside the client folder

[tniessen]

Well, crypto is a node-internal module... It is unrelated to all the stuff you do outside of the node process. Which dependency (injection) library do you use for clients? Something like require.js?

[fusiodarts]

We are implementing it in the client-side because we need that the client buy a product, so we have to generate the key for the payment gateway in the client-side.

We have webpack dependency installed, but nothing as require.js

[fusiodarts]

@tniessen sorry, the dependency (injection) library we are using babel

[tniessen]

You could probably use https://github.com/crypto-browserify/crypto-browserify (or alternatives, never used anything like that). That should work with webpack. However, modern browsers provide the SubtleCrypto API, which might be a better choice.

Ref #432

[fusiodarts]

It is ok @tniessen a lot of thanks. We are going to try it.
We implemented crypto-browserify, but we need 3DES encryption, and with crypto-browserify we only can use AES encryption.
We are going to check the Ref that you have sent me.

[tniessen]

I am closing this as this problem is unrelated to node.
