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, serde-json-core, and uuid

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

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
