在Swift中验证X509证书可以通过以下步骤实现:
import Security
import Foundation
guard let certificateURL = Bundle.main.url(forResource: "certificate", withExtension: "cer") else {
print("Certificate file not found")
return
}
guard let certificateData = try? Data(contentsOf: certificateURL) else {
print("Failed to read certificate file")
return
}
guard let certificate = SecCertificateCreateWithData(nil, certificateData as CFData) else {
print("Failed to create certificate object")
return
}
var trust: SecTrust?
let policy = SecPolicyCreateBasicX509()
guard SecTrustCreateWithCertificates(certificate, policy, &trust) == errSecSuccess else {
print("Failed to create trust object")
return
}
let options: NSDictionary = [
kSecTrustOptionAllowExpired: true,
kSecTrustOptionRequireRevPerCert: true,
kSecTrustOptionPolicy: policy
]
guard SecTrustSetOptions(trust!, options) == errSecSuccess else {
print("Failed to set trust options")
return
}
var trustResult: SecTrustResultType = .invalid
guard SecTrustEvaluate(trust!, &trustResult) == errSecSuccess else {
print("Failed to evaluate trust")
return
}
switch trustResult {
case .unspecified, .proceed:
print("Certificate is valid")
case .deny, .fatalTrustFailure, .invalid, .otherError:
print("Certificate is invalid")
@unknown default:
print("Unknown trust result")
}
这些步骤将帮助你在Swift中验证X509证书。请注意,这只是一个基本的示例,你可能需要根据你的具体需求进行适当的修改和扩展。
