/** |
|
* 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 ])) |
