+.Os
+.Sh NAME
+.Nm sun8icrypto
+.Nd driver for Allwinner Crypto Engine
+.Sh SYNOPSIS
+.Cd "sun8icrypto* at fdt?"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for the cryptographic processors on Allwinner
+A64 and H5 systems-on-a-chip.
+The Allwinner Crypto Engine is the successor to the earlier
+Allwinner Security System.
+.Pp
+The hardware includes a True Random Number Generator (TRNG) that is
+used as an entropy source for the
+.Xr rnd 4
+system, and implementations of various cryptographic algorithms
+that can be used with
+.Xr ipsec 4
+and
+.Xr crypto 4 .
+.Pp
+The following
+.Xr opencrypto 9
+algorithms are supported:
+.Pp
+.Bl -bullet -compact -offset indent
+.It
+.Dv CRYPTO_AES_CBC
+.It
+.Dv CRYPTO_AES_CTR
+.It
+.Dv CRYPTO_AES_ECB
+.It
+.Dv CRYPTO_AES_XTS
+.It
+.Dv CRYPTO_DES_CBC
+.It
+.Dv CRYPTO_DES_ECB
+.It
+.Dv CRYPTO_3DES_CBC
+.It
+.Dv CRYPTO_3DES_ECB
+.It
+.Dv CRYPTO_MD5
+.It
+.Dv CRYPTO_SHA1
+.It
+.Dv CRYPTO_SHA224
+.It
+.Dv CRYPTO_SHA256
+.It
+.Dv CRYPTO_SHA1_HMAC
+.It
+.Dv CRYPTO_SHA2_256_HMAC
+.El
+.Sh SEE ALSO
+.Xr crypto 4 ,
+.Xr ipsec 4 ,
+.Xr rnd 4 ,
+.Xr entropy 7 ,
+.Xr opencrypto 9
+.Sh HISTORY
+The
+.Nm
+device driver first appeared in
+.Nx 9.1 .
+.Sh CAVEATS
+The
+.Nm
+TRNG's underlying source of randomness is not documented by Allwinner,
+so is not trusted as a reliable source of entropy.
+Initial tests using NIST's SP800-90B tools showed highly biased
+runs of output, suggesting any potential physical source is not
+subject to whitening.
+.Pp
+Cryptographic operations using
+.Nm
+are generally slower than using the CPU on supported devices, but provide
+an advantage in terms of hardware offloading if the CPU is busy.
