Quoting from the Cloudflare article[1]: Red October is based on combinatorial techniques and trusted cryptographic primitives. We investigated using complicated secret primitives like Shamir's sharing scheme, but we found that a simpler combinatorial approach based on primitives from Go's standard library was preferable to implementing a mathematical algorithm from scratch. Which seems like a reasonable choice for smallish numbers of keys/sharers, especially given the data they're encrypting isn't exactly huge. Are there good libraries (for any language) implementing shared secrets?
