CORE_ERROR crypto_alg: RSA-SHA512: not found

Post by hkdan » Fri Jun 24, 2016 9:55 pm

Hi on my iPhone (ios9.3.2) with I try to connect with the following config:

Code: Select all

dev tun
persist-tun
persist-key
cipher AES-256-CBC
auth RSA-SHA512
tls-client
client
resolv-retry infinite
remote xxx.xxx.xxx.xxx port udp
lport 0
tls-remote "ovpnCert"
pkcs12 cert.p12
tls-auth cert-tls.key 1
ns-cert-type server
comp-lzo adaptive  
I get the error:

Code: Select all

EVENT: CORE_ERROR crypto_alg: RSA-SHA512: not found (ERR)
Does anybody know how to fix this problem, or is it a missing feature in OpenVPN 1.07?
Any help would be highly appreciated.

It looks like your app (1.07) does not support --auth RSA-SHA512

Try without specifying --auth on the server and client.

I have no access to the server. It is the provider that enables the connection with this method.
Is there a possibility that openvpn adds this RAS-Sch512 algorithem to one of its next versions of the IOS app?
