ios - 在运行时获取配置文件和证书的详细信息
<p><p>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<a href="https://stackoverflow.com/questions/18961267/get-the-expiration-date-of-a-provisioning-profile-at-run-time" rel="noreferrer noopener nofollow">this</a>但它在我的应用程序中无法正常工作。它最初为 <code>profilePath</code> 本身提供 nil。 </p>
<p>我正在使用 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(卡在 <code>sscanf</code> 方法中)。任何帮助表示赞赏。 </p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>我无法访问 Xcode 8/Swift 3.2，但这里是在 Swift 4 中执行您想要的操作所需的代码。我已经在几个可用的配置文件/证书上对其进行了测试，并且它会获取您请求的信息。 </p>
<p><strong>配置文件</strong></p>
<pre><code>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 = "<key>ExpirationDate</key>.*<date>(.*)</date>"
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
}

<p>我们需要进行一些操作，因为 Embedded.mobileprovision 文件如果不从十六进制转换就无法读取，然后只提取 plist 标记之间的内容。 </p>
<pre><code>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("<plist") ) { inPlist = true }
if( inPlist ) {plistString.append(" "); plistString.append( word ) }
if (word.contains("</plist")) { inPlist = false }
}
return plistString;
}
func hexStringtoAscii(_ hexString : String) -> String {
let pattern = "(0x)?({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)
}

<p>我已经验证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。 </p>
<p><strong>证书:</strong> </p>
<p>要获取证书信息，我可以使用以下方法使其工作:</p>
<pre><code>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 = "<key>DeveloperCertificates</key>\\s*<array>\\s*<data>([^<]*)</data>"
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)

}

<p>请注意，这只会检查安装时与应用捆绑的配置文件/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，如果在使用的设备上安装配置文件的其他机制(设备管理、安装具有较新通配符配置文件的另一个应用程序等)，应用程序仍有可能运行。但是，如果用于签署应用程序的证书已过期，即使设备上存在更新的配置文件，它也不会运行。 </p>
<p>对于证书信息，我仍然认为最安全的方法是使用openssl库来解密DER编码的x509证书，但是在base64解码证书数据后我能够做的解析似乎提取了你需要的信息. </p></p>
