Hi , I want to interact with Crypto Hardware from user space using openssl like libraries based applications through cryptodev-linux interface. it looks like openssl comes with cryptodev-linux support(through eng_cryptodev.c) . When I downloaded openssl,eng_cryptodev.c file is available by default. below link refers about eng_cryptodev.c for openssl support : http://repo.or.cz/w/cryptodev-linux.git/commitdiff/56cc4e3b8b761cb34f928f4eee59755d1f0afc53 Note:looks like there are some additional changes done on eng_cryptodev.c file available in updated openssl source code. There seems to be some changes/patches also available recently for cryptodev-linux,below contains reference information. http://rt.openssl.org/Ticket/Display.html?id=2770&user=guest&pass=guest Please let me know if my understanding is incorrect .
