Cargo Features

[dependencies]
http-signature-normalization-actix-extractor = { version = "0.2.0", default-features = false, features = ["sha-2"] }
default = sha-2

The sha-2 feature is set by default whenever http-signature-normalization-actix-extractor is added without default-features = false somewhere in the dependency tree.

sha-2 default = base64, sha2, subtle
