Hi,
I get this error. I have a fresh minimal install of Centos 7 with openssl.
kernel Linux 3.10.0-693.17.1
I have updated all the packages but I have this error coming when i am trying to test some encryption scripts:
OpenSSL Error: error:100AE081:elliptic curve routines:EC_GROUP_new_by_curve_name:unknown group
I have seen that there is quite a few people since Centos 6 with this issue but I have not since a solution for it.
Anyone is able to give some ideas?
Thanks in advance

Redhat don't support all possible ciphers in openssl and disable some at build time due to licensing/patent concerns.
The future appears to be RHEL or Debian. I think I'm going Debian.

CentOS 5 and 6 are deadest, do not use them.

Thanks is there a list of such ciphers not supported?

Don't know but it has a command to tell you the opposite: openssl list-cipher-algorithms

openssl ecparam -list_curves may also be informative.
