Hello Helder, If there is no enough random seed OpenSSL will not hang, just return an error.
Even /dev/random is opened in non-blocking mode. This is true only if OpenSSL is built with non-blocking mode. https://github.com/openssl/openssl/blob/master/crypto/rand/rand_unix.c If it hangs after some time could it be a handle leak? In the past, I had a similar problem and used "lsof" and "ulimit" commands to see is it reached. This error could be a possible track to a handle leak. setrlimit: Unable to set file descriptors limit to -1: Operation not permitted Regards, Zhivko On Mon, Nov 11, 2019, at 2:53 PM, Helder Guerreiro via Info-cyrus wrote: > On 10/11/19 00:19, Helder Guerreiro via Info-cyrus wrote: > > On 09/11/2019 23.34, Patrick Boutilier wrote: > >> Almost sounds like you are running out of entropy.
