SYNOPSIS


.Cd device crypto
.Cd device cryptodev

DESCRIPTION

The crypto 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 crypto device is created.

The following ioctl(2) calls apply only to the crypto 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.

FEATURES

Depending on hardware being present, the following symmetric and asymmetric cryptographic features are potentially available from /dev/crypto:

CRYPTO_DES_CBC
CRYPTO_3DES_CBC
CRYPTO_BLF_CBC
CRYPTO_CAST_CBC
CRYPTO_SKIPJACK_CBC
CRYPTO_MD5_HMAC
CRYPTO_SHA1_HMAC
CRYPTO_RIPEMD160_HMAC
CRYPTO_MD5_KPDK
CRYPTO_SHA1_KPDK
CRYPTO_AES_CBC
CRYPTO_ARC4
CRYPTO_MD5
CRYPTO_SHA1
CRK_MOD_EXP
CRK_MOD_EXP_CRT
CRK_DSA_SIGN
CRK_DSA_VERIFY
CRK_DH_COMPUTE_KEY
