Public constructors ### AbstractVerifier Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public AbstractVerifier () ```

## Public methods ### acceptableCountryWildcard Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public static boolean acceptableCountryWildcard (String cn) ```

| Parameters || |------|-----------------| | `cn` | `String`
| | Returns || |-----------|--------| | `boolean` |
| ### countDots Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public static int countDots (String s) ``` Counts the number of dots "." in a string.
| Parameters || |-----|--------------------------------------------| | `s` | `String`: string to count dots from
| | Returns || |-------|-----------------------| | `int` | number of dots
| ### getCNs Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public static String[] getCNs (X509Certificate cert) ```

| Parameters || |--------|--------------------------| | `cert` | `X509Certificate`
| | Returns || |----------------------------------------------------------------------|--------| | [String[]](https://developer.android.com/reference/java/lang/String) |
| ### getDNSSubjectAlts Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public static String[] getDNSSubjectAlts (X509Certificate cert) ``` Extracts the array of SubjectAlt DNS names from an X509Certificate. Returns null if there aren't any.
Note: Java doesn't appear able to extract international characters from the SubjectAlts. It can only extract international characters from the CN field.
(Or maybe the version of OpenSSL I'm using to test isn't storing the international characters correctly in the SubjectAlts?).

| Parameters || |--------|-------------------------------------------| | `cert` | `X509Certificate`: X509Certificate
| | Returns || |----------------------------------------------------------------------|-----------------------------------------------------------------| | [String[]](https://developer.android.com/reference/java/lang/String) | Array of SubjectALT DNS names stored in the certificate.
| ### verify Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public final void verify (String host, String[] cns, String[] subjectAlts, boolean strictWithSubDomains) ```

| Parameters || |------------------------|------------------| | `host` | `String`
| | `cns` | `String`
| | `subjectAlts` | `String`
| | `strictWithSubDomains` | `boolean`
| | Throws || |------------------------------------------------------------------------------------|---| | [SSLException](https://developer.android.com/reference/javax/net/ssl/SSLException) | | ### verify Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public final void verify (String host, SSLSocket ssl) ```

| Parameters || |--------|--------------------| | `host` | `String`
| | `ssl` | `SSLSocket`
| | Throws || |----------------------------------------------------------------------------|---| | [IOException](https://developer.android.com/reference/java/io/IOException) | | ### verify Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public final void verify (String host, X509Certificate cert) ```

| | `cert` | `X509Certificate`
| | Throws || |------------------------------------------------------------------------------------|---| | [SSLException](https://developer.android.com/reference/javax/net/ssl/SSLException) | | ### verify Added in[API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public final boolean verify (String host, SSLSession session) ``` Verify that the host name is an acceptable match with the server's authentication scheme.
| Parameters || |-----------|----------------------------------------------------------------| | `host` | `String`: the host name
| | `session` | `SSLSession`: SSLSession used on the connection to host
| | Returns || |-----------|--------------------------------------------| | `boolean` | true if the host name is acceptable
