sjcl | Stanford Javascript Crypto Library | Cryptography library

I am working on a route building code and have half a million record which taking around 3-4 hrs to get executed.

For creating dataframe:

Im trying to pass the result of the bcrypt hashing function into the user model below.

I can't seem be able to wrap my head around how to efficiently resolve this promise.

Heres the code:

We have an Expo React Native Project utilizing encryption. Our current encryption is based on SubtleCrypto / Web API [window.subtle.crypto], using AES-GCM 128, now we need to use a library that is universally available on all platforms [Web, iOS and Android], from my previous question, we've found SJCL that supports GCM mode and we can completely replace all the web-only based code BUT the challenge is that we need to ensure that all the current encrypted data is decrypted at this new library too, we have to make it so:

window.crypto.subtle.encrypt [AES-GCM 128] => (a) ---> SJCL.mode.gcm.decrypt(a)

Once we can do that successfully, we can fully replace the library and have universal platform support as well as backwards compatibility.

This means that we cannot change the way encryption is handled at all, as that is the requirement, and we're encrypting it exactly as the code below.

I got a very good lead here by Neneil94 but I'm still facing issues at encoding / formats; and here's the current code:

I’d like to decrypt an AES-encrypted string (CCM mode) in Python 3.

The following JavaScript code which is using the sjcl library is working correctly:

What I'm looking to achieve:

The code added below filters through a parsed HTML page looking for specific values. Each specific value is then added to its own specific list in the form of a dictionary. Once all the values are added to the lists the dictionaries within are then combined into a JSON blob that I can then export.

Note - This is part of a quick PoC, so it was written quick and dirty. Forgive me.

My problem:

When the following lists dictionaries are combined I do not encounter any issues when export the blob:

• jobs
• names
• dates
• summaries

However, when the locations list is added in order to be combined into the blob an IndexError exception is encountered. As shown in the image below:

IndexError Encountered

My Analysis:

I've found that sometimes the value is not found because it was not included in the parsed HTML for reason/s that I cannot control, ie. it was not added my the user when it was created. The issue in this case being that the len of the locations list being 14 whilst the len of the other lists being equal at 15 which is causing the IndexError exception when I combine the lists using a for loop.

My Question:

As shown in my code below, I'm trying to handle the issue by assigning a placeholder value, "null", when the scraped value is not found but for some reason the value is not applied and I still encounter the IndexError exception. Any help would be appreciated, thank you in advance.

My Code:

I am trying to rewrite the following code in Python. The original code is written in Javascript using the sjcl library.

I have a project based on Laravel with Bootstrap, which also includes some packages like bootstrap select (https://developer.snapappointments.com/bootstrap-select/)

I think the error comes from this package, but I cannot get the tooltip to work.

Console error:

I have a vanilla javascript project that is compiled and minified using Closure Compiler v20181210. I want to use SJCL in that project for crypto.

I copied this file into my own project and wrote code using the library. But when I try to compile it, Closure Compiler throws a bunch of errors from the library (pasted below).

On the SJCL website, it says that the file is compressed using Google Closure Compressor. So I imagine it should be compatible with Closure? Why is it not compiling then?

Also, I read about externs. But I want all the code to be in a single minified file. With externs, it looks like I would need another import for SJCL.

Some of the Closure Compiler Errors:

I'm generating new Ethereum addresses using the scep256k1 curve. Due to storage and hardware limitations, I'm only able to store the private key. I'm looking for ways to generate the public key for asymmetric encryption (NOT the Ethereum public address) in the browser.

It is my understanding that the public key can be derived from the scep256k1 private key, but I'm not sure how to do this in the browser, or whether this is even possible with existing libraries, but I've a hunch that it is. I'm currently trying to see if it is possible with Web3js, SJCL, or CryptoJS but am open to other options.

To provide a bit of an understanding of the flow here. Step 3 is what I'm currently trying to do:

1. Generate scep256k1 key pair using openSSL
2. Upload the private key to hardware device and give this to a user
3. User in web interface: use private key from hardware to get access to their public key, and reconstruct the Ethereum address.

Any pointers in the right direction are appreciated!
