Crate sp_application_crypto

Expand description

Traits and macros for constructing application specific strongly typed crypto wrappers.

Modules§

bandersnatch: Bandersnatch VRF application crypto types.
bls381: BLS12-381 crypto applications.
ecdsa: Ecdsa crypto types.
ecdsa_bls381: ECDSA and BLS12-381 paired crypto applications.
ed25519: Ed25519 crypto types.
key_types: Known key types; this also functions as a global registry of key types for projects wishing to avoid collisions with each other.
sr25519: Sr25519 crypto types.

app_crypto: Declares Public, Pair, Signature and ProofOfPossession types which are functionally equivalent to the corresponding types defined by $module but are new application-specific types whose identifier is $key_type.
app_crypto_pair_common: Declares Pair type which is functionally equivalent to $pair, but is new application-specific type whose identifier is $key_type. It is a common part shared between full_crypto and non full_crypto environments.
with_pair: Generate the given code if the pair type is available.
wrap: Implement bidirectional From and on-way AsRef/AsMut for two types, $inner and $outer.

CryptoTypeId: An identifier for a specific cryptographic algorithm used by a key pair
KeyTypeId: An identifier for a type of cryptographic key.

DeriveJunction: A since derivation junction description. It is the single parameter used when creating a new secret key from an existing secret key and, in the case of SoftRaw and SoftIndex a new public key from an existing public key.

AppCrypto: Application-specific cryptographic object.
AppPair: Application-specific key pair.
AppPublic: Application-specific public key.
AppSignature: Application-specific signature and Proof Of Possession
BoundToRuntimeAppPublic: Something that is bound to a fixed RuntimeAppPublic.
MaybeHash: Type which implements Hash in std, not when no-std (std variant).
RuntimeAppPublic: Runtime interface for an application’s public key.
RuntimePublic: Runtime interface for a public key.
Ss58Codec: Key that can be encoded to/from SS58.
