Deactivation TLS 1.1 encryption protocol on 24.09.2020

We would like to inform you about the deactivation of TLS 1.1 by September 24th 2020 and kindly ask you to share the following information with your IT department.

In order to ensure the best possible protection of your transaction data and to meet the ever increasing security requirements for ourselves and our partners, it is necessary to end the support for the encryption protocol TLS 1.1.

The approved protocol is TLS 1.2, which is completely supported by our system for incoming and outgoing connections.

This change affects all systems that are connected to the Computop Paygate.

This includes communication via server, browser access, access via mobile phone or tablet, access to the backend systems as well as single sign on access (e.g. SAP, PHP, Java, ...).

Not affected are sftp connections for file transfer.

Modern Internet browsers already support TLS 1.2 automatically:

  • Apple Safari:
    Desktop Safari from version 7 - OS X 10.9 (Mavericks) and higher
    Mobile Safari from version 5 - iOS 5 and higher

  • Google Chrome:
    Google Chrome from version 38
    Google Chrome from version 22 to 37 - on operating systems Windows XP SP3, Vista or higher (desktop), OS X 10.6 (Snow Leopard) or higher (desktop) and Android 2.3 (Gingerbread) or higher (mobile)

  • Mozilla Firefox:
    Firefox 27 from version 27
    Firefox 23 to 26 - compatible by separate setting (use about:config to enable TLS 1.2 by updating the configuration value security.tls.version.max for TLS 1.2 to 3)

  • Internet Explorer:
    Desktop and Mobile IE version 11 and above - you may need to turn off the TLS 1.1 setting in the Internet Options list | Advanced Settings
    Desktop IE versions 8, 9 and 10 - from Windows 7 or newer, but not by default

  • Microsoft Edge:
    Compatible in all versions

We would kindly ask all our customers to make sure that in their respective browsers (or scripts) the TLS 1.2 Protocol, which is needed for connections to the Computop web page, is activated.

The following Ciphers will be supported:

  • TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 (0xc02f) ECDH secp256r1 (eq. 3072 bits RSA)
  • TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 (0xc030) ECDH secp256r1 (eq. 3072 bits RSA)

If you experience any technical issues, we recommend that you contact your IT department for further help.

We provide you with a separate URL which you can use to test the connection from your systems:

The TLS 1.1 protocol is already no longer supported on this URL.
