MirOS Manual: crypto(4)

CRYPTO(4)                  BSD Programmer's Manual                   CRYPTO(4)

NAME

     crypto - hardware crypto access driver

SYNOPSIS

     pseudo-device crypto [count] [count]

DESCRIPTION

     The crypto driver provides userland applications access to hardware cryp-
     to support via the kernel. The /dev/crypto device 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 is 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  Set up a new crypto session for a new type of operation.

     CIOCFSESSION  Free a previously established session.

     CIOCCRYPT     Perform a crypto operation against a previously set up ses-
                   sion.

FEATURES

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

           CRYPTO_DES_CBC
           CRYPTO_3DES_CBC
           CRYPTO_BLF_CBC

           CRYPTO_SHA1_KPDK
           CRYPTO_AES_CBC
           CRYPTO_ARC4
           CRYPTO_MD5
           CRYPTO_SHA1
           CRK_MOD_EXP
