Cargo Features

curve25519-dalek-v2 = { version = "4.1.3", default-features = false, features = ["alloc", "precomputed-tables", "legacy_compatibility", "group", "group-bits", "digest", "serde", "zeroize"] }
default = alloc, precomputed-tables, zeroize

These default features are set whenever curve25519-dalek-v2 is added without default-features = false somewhere in the dependency tree.

alloc default

Enables alloc of optional zeroize

precomputed-tables default

Affects constants::ED25519_BASEPOINT_TABLE, constants::ED25519_BASEPOINT_TABLE, constants::RISTRETTO_BASEPOINT_TABLE, ristretto::RistrettoBasepointTable

group group-bits? = rand_core

Enables group

Affects edwards::SubgroupPoint

group-bits = group

Enables bits of ff

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.

ff group-bits?
rand_core group?
digest implicit feature

Enables digest


Traits for cryptographic hash functions and message authentication codes

serde implicit feature

Enables serde


A generic serialization/deserialization framework

zeroize default
