OSSL(4) Kernel Interfaces Manual OSSL(4) NAME ossl -- driver using OpenSSL assembly routines SYNOPSIS To compile this driver into the kernel, place the following lines in your kernel configuration file: device crypto device cryptodev device ossl Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): ossl_load="YES" DESCRIPTION The OpenSSL distribution includes architecture-specific implementations for some commonly used cryptographic algorithms. This driver adds a wrapper around these routines permitting them to be used by in-kernel cryptography consumers such as kernel TLS and IPsec. The ossl driver includes architecture-specific implementations for the fol- lowing architectures: * arm64 * amd64 * i386 The ossl driver includes support for the following algorithms: * AES-CBC * AES-GCM (amd64 only) * ChaCha20 * ChaCha20-Poly1305 (RFC 8439) * Poly1305 * SHA1 * SHA1-HMAC * SHA2-224 * SHA2-224-HMAC * SHA2-256 * SHA2-256-HMAC * SHA2-384 * SHA2-384-HMAC * SHA2-512 * SHA2-512-HMAC SEE ALSO crypto(4), intro(4), ipsec(4), crypto(7), crypto(9) HISTORY The ossl driver first appeared in FreeBSD 13.0. FreeBSD 15.1 May 4, 2023 OSSL(4)
