Cargo Features

[dependencies]
libp2p-secio = { version = "0.26.0", default-features = false, features = ["secp256k1", "aes-all"] }
default = secp256k1

The secp256k1 feature is set by default whenever libp2p-secio is added without default-features = false somewhere in the dependency tree.

secp256k1 default
aes-all = aesni

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](https://rust-lang.github.io/rfcs/3491-remove-implicit-features.html).
