Tests if the sha256 hash generated from data matches the provided checksum.
Tests if the sha256 hash generated from data matches the provided checksum. This method is optimized to a NO-OP when in fast evaluation mode.
Parameters
-
data- Data you want to hash -
length- Data length -
hash-checksum256*hash to compare to
Precondition
assert256 hash of data equals provided hash parameter.
Post Condition
Executes next statement. If was not true, hard return.
Example
checksum hash;
char data;
uint32_t length;
assert_sha256( data, length, hash )
//If the sha256 hash generated from data does not equal provided hash, anything below will never fire.
eosio::print("sha256 hash generated from data equals provided hash");
