### Methods
#### sha256(str, asciiOnly)
Hash string to sha256, set asciiOnly to true for better performace if you ensure input is ascii.
##### *str: `String`*
String to hash.
##### *asciiOnly: `Boolean` (default: `false`)*
Specify the string encoding is ASCII.
#### sha224(str, asciiOnly)
Hash string to sha224, set asciiOnly to true for better performace if you ensure input is ascii.
##### *str: `String`*
String to hash.
##### *asciiOnly: `Boolean` (default: `false`)*
Specify the string encoding is ASCII.
## Example
Code
```JavaScript
sha256('');
sha256('The quick brown fox jumps over the lazy dog', true);
sha256('The quick brown fox jumps over the lazy dog.', true);
sha256('The quick brown fox jumps over the lazy dog');
