如果/dev/random空了,系统会等到收集到足够的熵才会继续进行加密操作。 /dev/urandom在Linux系统里则被认为是伪随机数发生器,与前者不同,即使空掉,Linux也会持续生成伪随机数,所以不会被堵塞。 系统缓慢原因 由于openssl、tomcat等高加密要求的软件需要/dev/random所生成的真随机数来确保公匙不易于被猜测,与此同时...
rng-tools是从https://github.com/nhorman/rng-tools.git分支而来的,经过二次修改,可以支持uclibc的arm-linux-gcc交叉编译,原版并不支持uclibc,只支持GNU libc,所以在uclibc的平台不能使用。 编译方法 先编译libsysfs库,由于rng-tools需要依赖这个包: libsysfs下载地址:https://sourceforge.net/projects/linux-diag/...

Adding `Wants=systemd-udev-settle.service` provides a weak requirement to it, so that the `rngd` is started after it, if possible. Signed-off-by: Claudius Heine <c...@denx.de> Signed-off-by: Richard Purdie <richard.pur...@linuxfoundation.org> ...
