Abstract base class to inherit from if you want to create streams implementing
|
| 7 |
|
|
the same api as node crypto streams.
|

|
|
|
| 9 |
|
|
Requires you to implement 2 methods `_final` and `_update`. `_update` takes a
|
| 10 |
|
|
buffer and should return a buffer, `_final` takes no arguments and should return
|
| 11 |
|
|
a buffer.
|
| 12 |
|
|
|
| 13 |
|
|
|
| 14 |
|
|
The constructor takes one argument and that is a string which if present switches
|
| 15 |
|
|
it into hash mode, i.e. the object you get from crypto.createHash or
|
| 16 |
|
|
crypto.createSign, this switches the name of the final method to be the string
|
| 17 |
|
|
you passed instead of `final` and returns `this` from update.
