crypto

A cryptography library for the Odin language.

Supported

This package offers various algorithms implemented in Odin, along with useful helpers such as access to the system entropy source, and a constant-time byte comparison.

Implementation considerations

• The crypto packages are not thread-safe.
• Best-effort is make to mitigate timing side-channels on reasonable architectures. Architectures that are known to be unreasonable include but are not limited to i386, i486, and WebAssembly.
• Implementations assume a 64-bit architecture (64-bit integer arithmetic is fast, and includes add-with-carry, sub-with-borrow, and full-result multiply).
• Hardware sidechannels are explicitly out of scope for this package. Notable examples include but are not limited to:
  • Power/RF side-channels etc.
  • Fault injection attacks etc.
  • Hardware vulnerabilities ("apply mitigations or buy a new CPU").
• The packages attempt to santize sensitive data, however this is, and will remain a "best-effort" implementation decision. As Thomas Pornin puts it "In general, such memory cleansing is a fool's quest."
• All of these packages have not received independent third party review.
