# IP adresses, TLS versions & cipher suites

# IP addresses

All outbound traffic from Pagero will originate from one of these two IP addresses:

91.238.51.2
91.238.51.51

If you´re unable to open for/whitelist both, we can inform you which exact one is applicable in your specific case once the setup has been completed.

success

NOTE: Our platform is open for all inbound traffic (i.e. traffic to Pagero). In other words, we do not have open for/whitelist any external IPs.

# Transport Layer Security (TLS)

TLS allows client/server applications to communicate over the Internet in a way that is designed to prevent eavesdropping, tampering, and message forgery.

The primary goal of TLS is to provide a secure channel between two communicating peers; the only requirement from the underlying transport is a reliable, in-order data stream.

# Supported TLS versions

TLS v1.2 (RFC5246)
TLS v1.3 (RFC8446)

danger

NOTE: TLS v1.0 and TLS v1.1 (SSL encryption) were deprecated in 2020 and are no longer supported!

Please make sure to access our services using at least TLS v1.2.

# Supported HTTP ciphers suites

A cipher suite is a set of algorithms that help secure a network/HTTP connection.

The following cipher suites are supported by us:

ECDHE-ECDSA-AES128-GCM-SHA256
ECDHE-RSA-AES128-GCM-SHA256
ECDHE-ECDSA-AES256-GCM-SHA384
ECDHE-RSA-AES256-GCM-SHA384
ECDHE-ECDSA-CHACHA20-POLY1305
ECDHE-RSA-CHACHA20-POLY1305
DHE-RSA-AES128-GCM-SHA256
DHE-RSA-AES256-GCM-SHA384
