cryptodevSYNOPSIS
device crypto device cryptodevDESCRIPTION
The driver provides a device-independent framework to support cryptographic operations in the kernel. The cryptodev driver provides userland applications access to this support through the /dev/crypto device. This node primarily operates in an ioctl(2) based model, permitting a variety of applications to query device capabilities, submit transactions, and get results.If count given in the specification, and is greater than 0, a maximum of one device is created.
The following ioctl(2) calls apply only to the devices:
- CIOCGSESSION
- Setup a new crypto session for a new type of operation.
- CIOCFSESSION
- Free a previously established session.
- CIOCCRYPT
- Perform a crypto operation against a previously setup session.
