Module sp_core::crypto

Cryptographic utilities.

Modules

key_types

Known key types; this also functions as a global registry of key types for projects wishing to avoid collisions with each other.

Structs

AccountId32	An opaque 32-byte cryptographic identifier.
CryptoTypeId	An identifier for a specific cryptographic algorithm used by a key pair
CryptoTypePublicPair	A type alias of CryptoTypeId & a public key
Dummy	Dummy cryptography. Doesn't do anything.
KeyTypeId	An identifier for a type of cryptographic key.
ParseError	Error encountered while parsing Ss58AddressFormat from &'_ str unit struct for now.

Enums

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.
Infallible	The infallible type.
PublicError	An error type for SS58 decoding.
SecretStringError	An error with the interpretation of a secret.
Ss58AddressFormat	A known address (sub)format/network ID for SS58.

Constants

DEV_ADDRESS	The address of the associated root phrase for our publicly known keys.
DEV_PHRASE	The root phrase for our publicly known keys.
JUNCTION_ID_LEN	The length of the junction identifier. Note that this is also referred to as the CHAIN_CODE_LENGTH in the context of Schnorrkel.

Traits

CryptoType	Type which has a particular kind of crypto associated with it.
Derive	Derivable key trait.
ExposeSecret	Trait for accessing reference to SecretString.
IsWrappedBy	One type is wrapped by another.
Pair	Trait suitable for typical cryptographic PKI key pair type.
Public	Trait suitable for typical cryptographic PKI key public type.
Ss58Codec	Key that can be encoded to/from SS58.
UncheckedFrom	Similar to From, except that the onus is on the part of the caller to ensure that data passed in makes sense. Basically, you're not guaranteed to get anything sensible out.
UncheckedInto	The counterpart to UncheckedFrom.
Wraps	Opposite of IsWrappedBy - denotes a type which is a simple wrapper around another type.
Zeroize	Trait to zeroize a memory buffer.

Functions

set_default_ss58_version

Set the default "version" (actually, this is a bit of a misnomer and the version byte is typically used not just to encode format/version but also network identity) that is used for encoding and decoding SS58 addresses. If an unknown version is provided then it fails.

Type Definitions

SecretString

A store for sensitive data.

Derive Macros

Zeroize

Trait to zeroize a memory buffer.
