CRYPTO(4) BSD Kernel Interfaces Manual CRYPTO(4) NAME crypto -- hardware crypto access driver SYNOPSIS device crypto DESCRIPTION The crypto driver provides userland applications access to hardware crypto support via the kernel. The /dev/crypto device node primarily op- erates 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 ses- sion. FEATURES Depending on hardware being present, the following symmetric and asymmet- ric 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 FILES /dev/crypto crypto access device SEE ALSO hifn(4), ubsec(4), crypto(9) HISTORY The crypto driver first appeared in OpenBSD 3.0. The crypto driver was imported to FreeBSD in 5.0. BSD November 21, 2002 BSD
