x509-signature = { version = "0.5.0", default-features = false, features = ["std", "rsa", "webpki", "rustls"] }

The rsa feature is set by default whenever x509-signature is added without default-features = false somewhere in the dependency tree.

rsa default

webpki = w
rustls = r, std

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.

w std? webpki?

Enables webpki ^0.21.3

r rustls?

Enables rustls ^0.18.0
