default = fast, zeroize

These default features are set whenever ed25519-dalek is added without default-features = false somewhere in the dependency tree.

alloc batch? pem?

Enables alloc of curve25519-dalek, ed25519, optional serde, signature, and optional zeroize

serde:

Provide impls for types in the Rust core allocation and collections library including String, Box<T>, Vec<T>, and Cow<T>. This is a subset of std but may be enabled without depending on all of std.

batch = alloc, rand_core

Enables keccak

optional features

fast default

Enables precomputed-tables of curve25519-dalek

digest

Enables digest of signature

Affects hazmat::raw_sign_prehashed, hazmat::raw_verify_prehashed

hazmat

Exposes the hazmat module

Affects ed25519-dalek::hazmat

legacy_compatibility

Turns off stricter checking for scalar malleability in signatures

Enables legacy_compatibility of curve25519-dalek

pkcs8 pem?

Enables pkcs8 of ed25519

pem = alloc, pkcs8

Enables pem of ed25519

rand_core batch?

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.
