Cargo Features

askar-crypto = { version = "0.3.1", default-features = false, features = ["std", "alloc", "all_keys", "any_key", "aes", "bls", "chacha", "crypto_box", "ec_curves", "ed25519", "getrandom", "std_rng", "argon2", "arbitrary"] }
default = all_keys, alloc, any_key, crypto_box

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

std = alloc, std_rng

Enables std of serde and serde-json-core


Provide impls for common standard library types like Vec<T> and HashMap<K, V>.
Requires a dependency on the Rust standard library.

alloc default any_key crypto_box std?

all_keys default = aes, bls, chacha, ec_curves, ed25519
any_key default = alloc
aes all_keys = aes-core, aes-gcm, block-modes, cbc, cipher, hmac

Affects alg::aes

bls all_keys = bls12_381, hkdf

Affects alg::bls

chacha all_keys = chacha20poly1305

Affects alg::chacha20

crypto_box default = alloc, crypto_box_rs, ed25519, getrandom

Affects encrypt::crypto_box

ec_curves all_keys = elliptic-curve, k256, p256, p384
ed25519 all_keys crypto_box = curve25519-dalek, ed25519-dalek, x25519-dalek

Affects alg::ed25519, alg::x25519

getrandom crypto_box std_rng?

Enables getrandom of rand


Option: use getrandom package for seeding

Affects any::AnyKeyCreate.random, encrypt::KeyAeadMeta.random_nonce, random::default_rng, random::fill_random, repr::KeyGen.random, random::random_secret

std_rng std? = getrandom

Enables std and std_rng of rand

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.

aes-core aes?

Enables aes

aes-gcm aes?
argon2 implicit feature

Affects kdf::argon2

block-modes aes?
bls12_381 bls?
cbc aes?
chacha20poly1305 chacha?
cipher aes?
crypto_box_rs crypto_box

Enables crypto_box

ed25519-dalek ed25519?
elliptic-curve ec_curves?
hkdf bls?
hmac aes?
k256 ec_curves?

x25519-dalek ed25519?
arbitrary implicit feature

Enables arbitrary
