Struct Hash

Source 
pub struct Hash<const N: usize>(/* private fields */);
Expand description

A BytesN<N> generated by a cryptographic hash function.

The Hash<N> type contains a BytesN<N> and can only be constructed in contexts where the value has been generated by a secure cryptographic function. As a result, the type is only found as a return value of calling sha256, keccak256, or via implementing CustomAccountInterface since the __check_auth is guaranteed to receive a hash from a secure cryptographic hash function as its first parameter.

__Note:_ A Hash should not be used with storage, since no guarantee can be made about the Bytes stored as to whether they were in fact from a secure cryptographic hash function.
