|
digest by repeatedly calling zdigest_update() on chunks of data.

<method name = "string">
|
|
Return digest as printable hex string; caller should not modify nor

|
free this string. After calling this, you may not use zdigest_update()
|

on the same digest. If built without crypto support, returns NULL.
