Expand description

Trait impl’d by concrete types that represent digital cryptographic material (keys). For signatures, we rely on signature::Signature, which may be more widely implemented.

Key types must (as mandated by the AsRef<[u8]> bound) be a thin wrapper around the “bag-of-bytes” serialized form of a key which can be directly parsed from or written to the “wire”.

The ToFromBytes trait aims to provide similar simplicity by minimizing the number of steps involved to obtain a serializable key and ideally ensuring there is one signature type for any given signature system shared by all “provider” crates.

For signature systems which require a more advanced internal representation (e.g. involving decoded scalars or decompressed elliptic curve points) it’s recommended that “provider” libraries maintain their own internal signature type and use From bounds to provide automatic conversions.

Required Methods

Parse a key from its byte representation

Provided Methods

Borrow a byte slice representing the serialized form of this key
