20//! # Features
21//!
22//! | Feature | Description |
23//! | ------- | ----------- |
24//! | `alloc` | Enable features that require use of the heap. Currently all RSA signature algorithms require this feature. |
25//! | `std` | Enable features that require libstd. Implies `alloc`. |
26//! | `ring` | Enable use of the *ring* crate for cryptography. |
27//! | `aws-lc-rs` | Enable use of the aws-lc-rs crate for cryptography. Previously this feature was named `aws_lc_rs`. |
