    A: CryptoApi,
{ /* private fields */ }

Implementations

impl<A> CryptoWrapper<A>

where A: CryptoApi,

pub fn new() -> Self

pub fn sha256<B: Borrow<ManagedBuffer<A>>>( &self, data: B ) -> ManagedByteArray<A, SHA256_RESULT_LEN>

pub fn keccak256<B: Borrow<ManagedBuffer<A>>>( &self, data: B ) -> ManagedByteArray<A, KECCAK256_RESULT_LEN>

pub fn ripemd160<B: Borrow<ManagedBuffer<A>>>( &self, data: B ) -> ManagedByteArray<A, { crate::api::RIPEMD_RESULT_LEN }>

pub fn verify_bls( &self, key: &ManagedBuffer<A>, message: &ManagedBuffer<A>, signature: &ManagedBuffer<A> ) -> bool

pub fn verify_ed25519( &self, key: &ManagedBuffer<A>, message: &ManagedBuffer<A>, signature: &ManagedBuffer<A> )

Will crash if the verification fails.

The error comes straight form the VM, the message is “invalid signature”.

pub fn verify_secp256k1( &self, key: &ManagedBuffer<A>, message: &ManagedBuffer<A>, signature: &ManagedBuffer<A> ) -> bool

Note: the signature is minimum 2 bytes in length, the second byte encodes the length of the remaining signature bytes.

pub fn verify_custom_secp256k1( &self, key: &ManagedBuffer<A>, message: &ManagedBuffer<A>, signature: &ManagedBuffer<A>, hash_type: MessageHashType ) -> bool

pub fn encode_secp256k1_der_signature( &self, r: &ManagedBuffer<A>, s: &ManagedBuffer<A> ) -> ManagedBuffer<A>

Trait Implementations

impl<A> Default for CryptoWrapper<A>

where A: CryptoApi + Default,

fn default() -> CryptoWrapper<A>

Returns the “default value” for a type.
