SSL / TLS Ciphers

Helcim API calls are made over HTTPS (port 443) and the connection is secured using an SSL certificate with a SHA256 key. To adhere to strong PCI-DSS standards we've disconnected weak connections and ciphers, including SSLv3, TLS1.0 and TLS1.1.

Below is a complete list of allowed ciphers:

EECDH+ECDSA+SHA384
EECDH+ECDSA+SHA256
