    NAME

    
    
    crypto
    
     
    cryptodev
    
     - hardware crypto access driver
    
     
    

    SYNOPSIS

    device crypto device cryptodev  

    DESCRIPTION

    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.

     

    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
