PublicKeysTrustEvaluator

Uses the pinned public keys to validate the server trust. The server trust is considered valid if one of the pinned public keys match one of the server certificate public keys. By validating both the certificate chain and host, public key pinning provides a very secure form of server trust validation mitigating most, if not all, MITM attacks. Applications are encouraged to always validate the host and require a valid certificate chain in production environments.

ServerTrustEvaluating

Initializers

init(keys:​performDefaultValidation:​validateHost:​)

Creates a PublicKeysTrustEvaluator.

public init(keys:​ [SecKey] = Bundle.main.af.publicKeys, performDefaultValidation:​ Bool = true, validateHost:​ Bool = true)

Parameters

• keys:​ The SecKeys to use to validate public keys. Defaults to the public keys of all certificates included in the main bundle.
• performDefaultValidation:​ Determines whether default validation should be performed in addition to evaluating the pinned certificates. true by default.
• validateHost:​ Determines whether or not the evaluator should validate the host, in addition to performing the default evaluation, even if performDefaultValidation is false. true by default.

Methods

public func evaluate(_ trust:​ SecTrust, forHost host:​ String) throws
