Helper function that will sha3 any value using keccak256. Internally it will use Buffer.from(input, 'utf8') to process the input first. If you want to hash a hexString or ByteArray, use TronWeb.utils.ethersUtils.keccak256(input).

Usage

TronWeb.sha3(value);

Parameters

Parameter	Description	Data Type
string	The string that needs to be hashed using Keccak-256 SHA3 algorithm.	String
prefix	the result includes 0x prefix if set as true	Boolean

Returns

String - The result hashed using the Keccak-256 SHA3 algorithm.

Example

> var hash = TronWeb.sha3("some string to be hashed");
console.log(hash)
> '0xc4b9bbe7eb8797cf2818085dbcd6ea6662b3261c28810c318e079c8d0c691da6'
> var hashOfHash = TronWeb.sha3(hash, false)
> '0xc4b9bbe7eb8797cf2818085dbcd6ea6662b3261c28810c318e079c8d0c691da6'
