在运行时获取配置文件和证书的详细信息
我想在我的应用中获取并显示我的配置文件和分发证书的详细信息（例如到期日期和注册公司）。 我已经尝试过这个，但它在我的应用程序中无法正常工作。 它最初为profilePath提供nil。
我使用的是swift 2.3和Xcode 8.2.1。 我试图将该代码混合并匹配到我的应用程序中，因为我无法将其完全转换为swift（陷入sscanf方法）。 任何帮助表示赞赏。
我没有访问Xcode 8 / Swift 3.2，但这里是在Swift 4中做你想要的代码。我已经在我可以使用的几个配置文件/证书上测试了它，它得到了您要求的信息。
供应配置文件
func getProvisioningProfileExpirationDate() -> Date? { self.getCertificateExpirationDate() let profilePath: String? = Bundle.main.path(forResource: "embedded", ofType: "mobileprovision") if( profilePath != nil ) { let plistData = NSData(contentsOfFile: profilePath!) let plistDataString = String(format: "%@", plistData!) var plistString: String = extractPlist(fromMobileProvisionDataString:plistDataString) let pattern = "ExpirationDate .*(.*) " let regex = try! NSRegularExpression(pattern: pattern, options: .caseInsensitive) let textCheckingResult : NSTextCheckingResult = regex.firstMatch(in: plistString, options: NSRegularExpression.MatchingOptions(rawValue: UInt(0)), range: NSMakeRange(0, plistString.characters.count))! let matchRange : NSRange = textCheckingResult.range(at: 1) let expirationDateString : String = (plistString as NSString).substring(with: matchRange) let dateFormatter = DateFormatter() dateFormatter.locale = Locale.current dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ssZ" print( "Profile expires: \(dateFormatter.date(from: expirationDateString)!)" ) return dateFormatter.date(from: expirationDateString)! } return nil }
我们需要做一些操作，因为embedded.mobileprovision文件如果没有从hex转换它是不可读的，然后只取出plist标签之间的东西。
func extractPlist( fromMobileProvisionDataString:String ) -> String { // Remove brackets at beginning and end var range = Range(NSMakeRange(0, 1), in: fromMobileProvisionDataString) var plistDataString = fromMobileProvisionDataString.replacingCharacters(in:range!, with: "") range = Range(NSMakeRange(plistDataString.count-1, 1), in: plistDataString) plistDataString.replaceSubrange(range!, with: "") // Remove spaces plistDataString = plistDataString.replacingOccurrences(of: " ", with: "") // convert hex to ascii let profileText = hexStringtoAscii( plistDataString ) // I tried using regular expressions and normal NSString operations to get this, but it simply wouldn't work, so I went with this ugly method. // return extractPlistText(fromProfileString:profileText) // Remove whitespaces and new lines characters and splits into individual lines. let profileWords = profileText.components(separatedBy: CharacterSet.newlines) var plistString = ""; var inPlist = false; for word in profileWords { if( word.contains(" String { let pattern = "(0x)?([0-9a-f]{2})" let regex = try! NSRegularExpression(pattern: pattern, options: .caseInsensitive) let nsString = hexString as NSString let matches = regex.matches(in: hexString, options: [], range: NSMakeRange(0, nsString.length)) let characters = matches.map { Character(UnicodeScalar(UInt32(nsString.substring(with: $0.range(at: 2)), radix: 16)!)!) } return String(characters) }
我已经validation这可以从物理设备上的embedded.mobileprovision文件中提取到期日期。 从配置文件plist数据中提取其他元素是微不足道的。
证书：
为了获得证书信息，我能够使用以下方法使其工作：
func getCertificateExpirationDate() -> Date? { let profilePath: String? = Bundle.main.path(forResource: "embedded", ofType: "mobileprovision") if( profilePath != nil ) { let plistData = NSData(contentsOfFile: profilePath!) let plistDataString = String(format: "%@", plistData!) var plistString: String = extractPlist(fromMobileProvisionDataString:plistDataString) // Trying to extract thecert information aswell, but haven't gotten it to work. let certPattern = "DeveloperCertificates \\s*\\s*([^<]*)" let certRegex = try! NSRegularExpression(pattern: certPattern, options: .caseInsensitive) let certCheckingResult : NSTextCheckingResult = certRegex.firstMatch(in: plistString, options: NSRegularExpression.MatchingOptions(rawValue: UInt(0)), range: NSMakeRange(0, plistString.characters.count))! let certMatchRange : NSRange = certCheckingResult.range(at: 1) let certDataString : String = (plistString as NSString).substring(with: certMatchRange) let decodedData = Data(base64Encoded: certDataString, options: []) let decodedString = String( data: decodedData!, encoding: .ascii ) let cfData = decodedData as! CFData let certificate: SecCertificate = SecCertificateCreateWithData(nil, cfData)! var description: CFString = SecCertificateCopySubjectSummary(certificate)! print( "Certificate name: \(description)") let certDate = self.extractCertExpirationDate(fromDecodedCertDataString: decodedString!) print( "Certificate expires: \(certDate)") let certOrg = self.extractCertOrg(fromDecodedCertDataString: decodedString!) print( "Certificate organization: \(certOrg)") return certDate } return nil } func extractCertExpirationDate( fromDecodedCertDataString: String ) -> Date { // Remove new lines characters and split into individual lines. let certWords = fromDecodedCertDataString.components(separatedBy: CharacterSet.newlines) var foundWWDRCA = false; var certStartDate = "" var certEndDate = "" var certOrg = "" for word in certWords { if( foundWWDRCA && (certStartDate.isEmpty || certEndDate.isEmpty)) { var certData = word.prefix(13) if( certStartDate.isEmpty && !certData.isEmpty ) { certStartDate = String( certData ); } else if( certEndDate.isEmpty && !certData.isEmpty ) { certEndDate = String( certData ); } } if( word.contains("Apple Worldwide Developer Relations Certification Authority") ) { foundWWDRCA = true } } let dateFormatter = DateFormatter() dateFormatter.locale = Locale.current dateFormatter.dateFormat = "yyMMddHHmmssZ" return dateFormatter.date(from: certEndDate)! } func extractCertOrg( fromDecodedCertDataString: String ) -> String { // Remove new lines characters and split into individual lines. let certWords = fromDecodedCertDataString.components(separatedBy: CharacterSet.newlines) var foundWWDRCA = false; var certStartDate = "" var certEndDate = "" var certOrg = "" for word in certWords { if( foundWWDRCA && (certStartDate.isEmpty || certEndDate.isEmpty)) { var certData = word.prefix(13) if( certStartDate.isEmpty && !certData.isEmpty ) { certStartDate = String( certData ); } else if( certEndDate.isEmpty && !certData.isEmpty ) { certEndDate = String( certData ); } } else if( foundWWDRCA && word.contains("\u{17}") && certOrg.isEmpty) { var orgString = word.suffix(word.count-1) certOrg = String( orgString.prefix(orgString.count - 1)) } if( word.contains("Apple Worldwide Developer Relations Certification Authority") ) { foundWWDRCA = true } } return certOrg }
请注意，这仅检查安装时与应用程序捆绑在一起的配置文件/证书。 它不会检查设备上的其他可能有效的配置文件。 因此，即使嵌入的配置文件已过期，如果在设备上安assembly置文件的其他机制（设备管理，使用较新的通配符配置文件安装另一个应用程序等），应用程序仍有可能仍然可以运行。 但是，如果用于对应用程序签名的证书已过期，则即使设备上存在较新的配置文件，也不会运行该证书。
对于证书信息，我仍然认为最安全的方法是使用openssl库来描述DER编码的x509证书，但是我在base64解码证书数据后能够进行的解析似乎可以提取您需要的信息。
