      SocketLabs Supported TLS Protocols

      This article outlines the TLS protocols supported by SocketLabs. It details the specific TLS versions, ciphers, hashes and key-exchanges compatible with SocketLabs systems.

      We are transitioning our services to newer, more secure, TLS protocols.  Presently our Portal and SocketLabs API's will support the following protocols:

      Protocols

      • TLS 1.2
      • TLS 1.3

      Ciphers

      • Triple DES 168
      • AES 128/128
      • AES 256/256

      Hashes

      • MD5
      • SHA
      • SHA 256
      • SHA 384
      • SHA 512

      Key-Exchanges

      • Diffie-Hellman
      • PKCS
      • ECDH

       These cipher suites use Microsoft's naming conventions.

      Cipher Suites

      • TLS_AES_256_GCM_SHA384
      • TLS_AES_128_GCM_SHA256
      • TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
      • TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
      • TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384
      • TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256
      • TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384
      • TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
      • TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384
      • TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256

      Our SMTP, Injection, and Engagement Tracking sites support the following protocols. These protocols will be removed in the near future:
