cralgebra

A fast crypto algebra library.

Status

The current version is to be considered unstable, and breaking changes are possible. New features and fixes will be added in small incremental releases.

• ✅: complete
• ⚡: partial
• ❌: none

"Complete" optimization here refers to using optimal algorithms. SIMD and/or inline assembly may also be considered in the future.

Using the API

See the documentation.

Performance

Run this to measure latencies for different operations:

cargo run --example bench --release

This Cargo.toml configuration is recommended for maximum performance:

[profile.release]
opt-level = 3
debug-assertions = false
overflow-checks = false
lto = true
panic = 'unwind'
incremental = false
codegen-units = 1
rpath = false

Further tips:

• Use the most specific type or method for each task.
• Use MontgomeryDyn instead of ModularDyn if doing multiple operations in series, containing multiplications.

Alternative projects

• feanor-math: more featured, with a different approach to API organization.
