pwall - a lightweight, open-source, universal paper wallet generator

Description

Using third-party services to generate paper wallets should be avoided without proper code auditing by independent entities.
Unnecessary codes and poorly written libraries are often used, creating a huge security risk for users.
Some services advertise that their generator works offline, and thus its users are immune to private key theft. However, there is still a possibility that an offline paper wallet generator creates keys deterministically without ever needing to communicate this information in any way. (see: https://medium.com/mycrypto/disclosure-key-generation-vulnerability-found-on-walletgenerator-net-potentially-malicious-3d8936485961)
For this reason, I wouldn't trust any random websites offering offline paper wallet generators without proper investigation.
pwall, on the other hand, contains no bloat but only the essentials. Feel free to use it. https://pwall-org.github.io/pwall/
