side-channel
Advanced tools
Package description
The side-channel npm package is designed to provide mechanisms for securely handling and transmitting sensitive information within a JavaScript environment. It is particularly useful in contexts where preventing information leakage is critical, such as in cryptographic operations or when handling personal data. The package offers functionalities to create secure channels for data, ensuring that the data is not exposed to unintended scopes or leaked through side channels.
Creating a secure side channel
This feature allows the creation of a secure side channel where you can safely store and retrieve data. The `set` method is used to store data associated with a given key, ensuring that the data is not accessible outside the intended scope.
const SideChannel = require('side-channel');
const channel = new SideChannel();
channel.set(key, value);Retrieving data from a secure side channel
This code snippet demonstrates how to retrieve data from a secure side channel. The `get` method is used to access the data associated with a specific key, ensuring that the operation is safe and the data integrity is maintained.
const value = channel.get(key);The 'secure-context' package provides functionalities similar to 'side-channel' by offering a secure environment for executing code and handling data. It focuses on creating isolated execution contexts to prevent data leakage, which is a similar goal to what 'side-channel' achieves with its secure data handling capabilities.
While 'cryptiles' is more focused on cryptographic utilities, it shares the goal of secure data handling with 'side-channel'. 'cryptiles' offers functions for securely generating random strings and fixed-size cryptographic tokens, which can be seen as complementary to the secure data transmission and storage functionalities provided by 'side-channel'.
