/**
|
|
* Computes the [[link-eip-191]] personal-sign message digest to sign.
|
|
*
|
|
* This prefixes the message with [[MessagePrefix]] and the decimal length
|
|
* of %%message%% and computes the [[keccak256]] digest.
|
|
*
|
|
* If %%message%% is a string, it is converted to its UTF-8 bytes
|
|
* first. To compute the digest of a [[DataHexString]], it must be converted
|
|
* to [bytes](getBytes).
|
|
*
|
|
* @example:
|
|
* hashMessage("Hello World")
|
|
* //_result:
|
|
*
|
|
* // Hashes the SIX (6) string characters, i.e.
|
|
* // [ "0", "x", "4", "2", "4", "3" ]
|
|
* hashMessage("0x4243")
|
|
* //_result:
|
|
*
|
|
* // Hashes the TWO (2) bytes [ 0x42, 0x43 ]...
|
|
* hashMessage(getBytes("0x4243"))
|
|
* //_result:
|
|
*
|
|
* // ...which is equal to using data
|
|
* hashMessage(new Uint8Array([ 0x42, 0x43 ]))
|
|
* //_result:
|
|
