Weird error with OpenSSL - "first num too large"

[glestwid]

My commands for preparing a certificate:

root@porteus:/mnt/sda1/porteus/base# openssl version
OpenSSL 1.0.2o 27 Mar 2018
root@porteus:/mnt/sda1/porteus/base# openssl req -new -out wso2-study1.csr -newkey rsa:2048 -nodes -sha256 -keyout wso2-study1.key -config /tmp/req.conf

The corresponding /tmp/req.conf:

[req]
distinguished_name = req_distinguished_name
req_extensions = v3_req
prompt = no
[req_distinguished_name]
C = RU
ST = Moscow
L = Moscow
O = "Credit Swiss"
OU = IT
CN = wso2.endocs.ru
[v3_req]
keyUsage = keyEncipherment, dataEncipherment
extendedKeyUsage = serverAuth, clientAtuth
subjectAltName = @alt_names
[alt_names]
DNS.1 = wso2.endocs.ru

What should I do to eliminate this error?

Looks like a typo to me. Change clientAtuth to clientAuth where you’re setting the values for extendedKeyUsage
