A collection of cryptography primitives written in Rust.
This library contains primarily the following cryptographic primitives:
- The Tip5 hash function
- Lattice-crypto
- arithmetic for the quotient ring
$\mathbb{F}_ p[X] / \langle X^{64} + 1 \rangle$ - arithmetic for modules over this quotient ring
- a IND-CCA2-secure key encapsulation mechanism
- Lattice-Based Cryptography in Miden VM
- arithmetic for the quotient ring
-
BFieldElement
,XFieldElement
- The prime-field type
$\mathbb{F}_p$ where$p = 2^{64} - 2^{32} + 1$ - The extension field
$\mathbb{F}_p[x]/(x^3 - x + 1)$ - A codec trait for encoding and decoding structs as
Vec
s ofBFieldElement
- An efficient prime for number-theoretic transforms
- The prime-field type
- NTT
- Number Theoretic Transform (discrete Fast Fourier Transform)
- Anatomy of a STARK, Part 6: Speeding Things Up
- Univariate and multivariate polynomials
- Merkle Trees
- Merkle Mountain Ranges
While twenty-first's version is 0.x.y
, releasing a new version:
- Is the release backwards-compatible?
Then the new version is
0.x.y+1
. Otherwise the new version is0.x+1.0
. - Checkout the last commit on Mjolnir, and run
make bench-publish
. Save the benchmark's result and verify that there is no performance degradation. - Create a commit that increases
version = "0.x.y"
in twenty-first/Cargo.toml. The commit message should give a one-line summary of each release change. Include the benchmark result at the bottom. - Have a
v0.x.y
git tag on this commit created. (git tag v0.x.y [sha]
,git push upstream --tags
) - Have this commit
cargo publish
ed on crates.io and in GitHub tags.
If you do not have the privilege to create git tags or run cargo publish
, submit a PR and the merger will take care of these.
