Android can'；不能生成密钥散列

我已尝试实现以下内容，以便回答：

13） 再次复制以下代码并粘贴

opensslbase64-in debug_sha.txt>debug_base64.txt

当我尝试第13点（上面）时，我得到错误：

openssl.exe has stopped working.

Illegal option: Alami.android\debug.keystore keytool -list [OPTION]...

我还尝试使用：

keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64

但我得到了一个错误：

openssl.exe has stopped working.

Illegal option: Alami.android\debug.keystore keytool -list [OPTION]...

您可以通过编程直接创建它。

try {
            PackageInfo info = getPackageManager().getPackageInfo(
                    "com.package.mypackage", 
                    PackageManager.GET_SIGNATURES);
            for (Signature signature : info.signatures) {
                MessageDigest md = MessageDigest.getInstance("SHA");
                md.update(signature.toByteArray());
                Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
                }
        } catch (NameNotFoundException e) {

        } catch (NoSuchAlgorithmException e) {

        }

只需在onCreate方法中添加此代码。

try {
            PackageInfo info = getPackageManager().getPackageInfo(
                    "com.package.mypackage", 
                    PackageManager.GET_SIGNATURES);
            for (Signature signature : info.signatures) {
                MessageDigest md = MessageDigest.getInstance("SHA");
                md.update(signature.toByteArray());
                Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
                }
        } catch (NameNotFoundException e) {

        } catch (NoSuchAlgorithmException e) {

        }

您将在日志中获得keyhash。您可以通过编程直接创建它。

try {
            PackageInfo info = getPackageManager().getPackageInfo(
                    "com.package.mypackage", 
                    PackageManager.GET_SIGNATURES);
            for (Signature signature : info.signatures) {
                MessageDigest md = MessageDigest.getInstance("SHA");
                md.update(signature.toByteArray());
                Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
                }
        } catch (NameNotFoundException e) {

        } catch (NoSuchAlgorithmException e) {

        }

            for (Signature signature : info.signatures) {
                MessageDigest md = MessageDigest.getInstance("SHA");
                md.update(signature.toByteArray());
                Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
                }
        } catch (NameNotFoundException e) {

        } catch (NoSuchAlgorithmException e) {

        }

您将在日志中获得密钥哈希。尝试从下载openssl，然后执行

try {
            PackageInfo info = getPackageManager().getPackageInfo(
                    "com.package.mypackage", 
                    PackageManager.GET_SIGNATURES);
            for (Signature signature : info.signatures) {
                MessageDigest md = MessageDigest.getInstance("SHA");
                md.update(signature.toByteArray());
                Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
                }
        } catch (NameNotFoundException e) {

        } catch (NoSuchAlgorithmException e) {

        }

keytool -exportcert -keystore YOUR_PATH_HERE/.android/debug.keystore | PATH_TO_BIN_FOLDER_OF_SSL_DIRECTORY_IN_C:/openssl.exe sha1 -binary | PATH_TO_BIN_FOLDER_OF_SSL_DIRECTORY_IN_C:/openssl.exe base64

尝试从下载openssl，然后执行

keytool -exportcert -keystore YOUR_PATH_HERE/.android/debug.keystore | PATH_TO_BIN_FOLDER_OF_SSL_DIRECTORY_IN_C:/openssl.exe sha1 -binary | PATH_TO_BIN_FOLDER_OF_SSL_DIRECTORY_IN_C:/openssl.exe base64
