# safexcel(4)

Inside Secure SafeXcel-IP-97 cryptographic offload engine

## NAME

**safexcel** – Inside Secure SafeXcel-IP-97 cryptographic offload engine

## SYNOPSIS

To compile this driver into the kernel, place the following lines in your kernel configuration file:

**device crypto** **device cryptodev** **device safexcel**

Alternatively, to load the driver as a module at boot time, place the following line in [loader.conf(5)](/loader.conf/5.md):

```
safexcel_load="YES"
```

## DESCRIPTION

The **safexcel** driver implements [crypto(4)](/crypto/4.md) support for the cryptographic acceleration functions of the EIP-97 device found on some Marvell systems-on-chip. The driver can accelerate the following AES modes:

- AES-CBC

- AES-CTR

- AES-XTS

- AES-GCM

- AES-CCM

**safexcel** also implements SHA1 and SHA2 transforms, and can combine AES-CBC and AES-CTR with SHA1-HMAC and SHA2-HMAC for encrypt-then-authenticate operations.

## HARDWARE

The **safexcel** driver supports the cryptographic acceleration functions of the Inside Secure EIP-97 device found on some Marvell systems-on-chip.

## SEE ALSO

## HISTORY

The **safexcel** driver first appeared in FreeBSD 13.0.
