I want to set self-signed certificates in thunderbird but got some warnings when I try to sent message:
Unable to put a digital signature. Make sure that the certificates specified in the account settings are valid and reliable.
I've made next steps:
1. Create CA certificates:
openssl req -new -x509 -extensions v3_ca -keyout private/cakey.pem -out cacert.pem -days 365 -config ./openssl.conf
2. Made pkcs#12 container for user:
openssl req -new -nodes -out $name-req.pem -keyout private/$name-key.pem -days 365 -config ./openssl.conf openssl ca -out $name-cert.pem -days 365 -config ./openssl.conf -infiles $name-req.pem openssl pkcs12 -export -in $name-cert.pem -inkey private/$name-key.pem -certfile cacert.pem -name "description" -out $name-cert.p12
Also, i've added *.p12 file and CA certificate to thunderbird. What should I fix? Thanx a lot.
