Blind RSA in circl ignored the reader you passed it

Cloudflare's circl has a partially blind RSA signer. Its Blind method takes an io.Reader. The blinding factor used that reader. The salt did not. It read from crypto/rand directly.

  • Circl library's partially blind RSA signer accepts io.Reader
  • Salt generated directly from crypto/rand, not from reader
  • Fix involves generating salt with io.ReadFull(random, salt)

Load Balancers and Reverse Proxies: Distributing Traffic Once It's Already Arrived

Every post in this series so far has been about getting traffic to the right network and the right host — routing between subnets, DNS resolving a domain to an IP, TCP getting bytes there reliably.

  • Reverse proxies act as intermediaries between clients and servers
  • Load balancing directs incoming requests to appropriate servers
  • Layer 7 load balancing makes decisions based on request content

Writing Online for 30 Days: What Actually Brings Readers (It's Not Posting More)

Thirty days of publishing will teach you things that thirty articles about writing never will. The main lesson is uncomfortable: the writing is maybe half of it.

  • Specific headlines with numbers or testable claims attract clicks
  • Deeply developed posts on one idea perform better than multifaceted ones
  • Engaging in discussions on others' work builds credibility and visibility

Discrete Mathematics for Computer Science: The 10-Module Zero-Fluff Roadmap

Discrete Mathematics is often taught as an abstract chore—pages of Greek symbols, detached lemma statements, and dry textbook proofs.

  • Discrete Mathematics forms unseen backbone of computing systems
  • Binary Dose releases 10-module Zero-Fluff Discrete Math roadmap
  • Course covers 31 topics with rigorous mathematical focus
