//! Public-key signatures //! //! This module re-exports all members of the default signing scheme, currently //! [`ed25519`](ed25519/index.html), hence e.g. `sign` refers to //! [`ed25519::sign`](ed25519/fn.sign.html). //! //! # Security model //! The [`sign()`](ed25519/fn.sign.html) function is designed to meet the standard //! notion of unforgeability for a public-key signature scheme under //! chosen-message attacks. //! //! # Selected primitive //! [`crypto::sign::sign`](ed25519/fn.sign.html) is `ed25519`, a signature scheme specified in //! [Ed25519](http://ed25519.cr.yp.to/). This function is conjectured to meet the //! standard notion of unforgeability for a public-key signature scheme under //! chosen-message attacks. //! //! # Alternate primitives //! //! ---------------------------------------------------------------------------------- //! |`crypto_sign` | PUBLICKEYBYTES | SECRETKEYBYTES | BYTES | //! |--------------------------------------|----------------|----------------|-------| //! |`crypto_sign_ed25519` | 32 | 64 | 64 | //! |`crypto_sign_edwards25519sha512batch` | 32 | 64 | 64 | //! ---------------------------------------------------------------------------------- //! //! `crypto_sign_edwards25519sha512batch` is a prototype.
