Issue/Introduction

The following table lists cipher suites that are shipped with the appliance for a specific version of SGOS.

For additional information, refer to the "Managing X.509 Certificates" chapter in the SGOS Administration Guide.

Resolution

Notes:

  • In the Strength column, "Export" refers to the 1990s-era cryptography export restrictions that limited key length to 40 bytes. Those restrictions are no longer in force, but the Export strength category remains in OpenSSL. These ciphers are thus supported on the appliance for historical reasons.
  • In the Shipped with columns, "x" means that the cipher is available in all releases of the specified version.
  • In the Shipped with columns, a specific release (such as "6.6.5.13") means that the cipher is available starting in that release.
  • Access logs record unsupported ciphers under their hex values. For example, TLS_AES_128_GCM_SHA256 is unsupported on version 6.7.x and is access-logged as
    “0x1301(unsupported)”.
