# DKIM

[back to index]

DESCRIPTION

Purpose | A `DKIM` handle is returned by successful calls to `dkim_sign()` and `dkim_verify()`, and passed to all of the message processing functions. It contains per-message context-specific information about the message. When processing of the message is complete, it must be destroyed using a call to `dkim_free()`.

NOTES

- More than one `DKIM` handle may exist at any given time. There is no memory shared between these handles, so two different handles may be concurrently accessed in separate threads.
