rtl_entropy -e causes sigsegv

[ghost]

I've run rtl_entropy -f 74M -e and the output is as follows snip the last few lines

Any ideas, works fine without -e

Bump, still an issue, just reproduced it on my CentOS 8 system.

G'day, thanks for writing in again.

I can confirm it does this for me too on debian 10.4, I've narrowed itt down the EVP_EncryptInit_ex() function from OpenSSL, I imagine I'm not calling it with the correct parameters.

I'll have a crack at fixing it over the next week or two, but if I can't immediately figure it out, I plan to push on with me ground up re-write. I've learnt a lot since I did this code!
