Abstract: Cryptographic hash functions are essential for securing data integrity in systems such as digital signatures, blockchain networks, and secure communication protocols. Among the widely ...

Birthday attacks exploit the collision probability of hash functions. Collision resistance requires sufficiently large hash outputs. Modern blockchains use 256-bit hashes to mitigate collision risks.

The Secure Multiuser Fileserver API provides encrypted file storage with per-user isolation using ZFS datasets. Each user's files are stored in their own encrypted ZFS dataset which is only mounted ...

Each user session is assigned a dedicated Docker container that runs until the browser tab is closed. If your code imports a package that is not available, the sandbox automatically installs it from ...
