“Requirements for Connecting Using ATS

With ATS fully enabled, your app’s HTTP connections must use HTTPS and must satisfy the following security requirements:

  • The server certificate must meet at least one of the following trust requirements:The negotiated Transport Layer Security version must be TLS 1.2
    • Issued by a certificate authority (CA) whose root certificate is incorporated into the operating system
    • Issued by a trusted root CA and installed by the user or a system administrator
  • The negotiated TLS connection cipher suite must support forward secrecy (FS) and be one of the following:
  • The leaf server certificate must be signed with one of the following types of keys:
    • Rivest-Shamir-Adleman (RSA) key with a length of at least 2048 bits
    • Elliptic-Curve Cryptography (ECC) key with a size of at least 256 bits
  • In addition, the leaf server certificate hashing algorithm must be Secure Hash Algorithm 2 (SHA-2) with a digest length of at least 256 (that is, SHA-256 or greater).”

It is also recommended to follow the ATS requirements which is more secure way for SSL communication.
