QuickAssist Technology Cryptographic API—Security Software
There are several open-source projects which implement these protocols. These include
Openswan* (which implements IPSec), OpenSSL* (which implements SSL/TLS), and
Racoon* (which implements IKE on FreeBSD). These in turn can be configured to use
OCF for their cryptographic operations. Using the OCF shim described in Section 12.9,
customers may be able to take advantage of cryptographic acceleration in the
Openswan and OpenSSL software suites.
12.11 Error Handling
In the case of an error occurring when an API function is invoked, the API function will
return with the error condition and no callback function will be called. Table 22 shows
the status values that are defined in cpa.h, along with their descriptions.
