# dk_getsig()

SYNOPSIS |
    #include <dk.h>
    DK_STAT dk_getsig(
    	DK *dk,
            unsigned char *buf,
            size_t len
    );
Compute and retrieve the signature for a message.
DESCRIPTION |
Called When | `dk_getsig()` is called after `dk_eom()` when `dk` is a signing handle, i.e. one returned by an earlier call to `dk_sign()`.
ARGUMENTS |
Argument | Description
--- | ---
dk | Message-specific handle, returned by `dk_sign()`.
buf | A buffer into which the base64-encoded signature should be stored.
len | Number of bytes available at `buf`.
NOTES | It is an error to call this function with a handle that was created using `dk_verify()`.
