对于谷歌短信哈希码:https ://developers.google.com/identity/sms-retriever/verify#computing_your_apps_hash_string
- 将用于签署应用程序的证书转换为小写十六进制字符串
- 将该十六进制字符串附加到应用程序包名称中,以单个空格分隔
- 计算组合字符串的 SHA-256 并将结果转换为 Base64 字符串
- Base64 字符串的前 11 个字符是 SMS 中使用的哈希值
对于 HMS SMS 哈希码:您可以通过实现以下类来获取您的哈希值:
public class hashcodeHMS extends ContextWrapper {
public static final String TAG = hashcodeHMS.class.getSimpleName();
public hashcodeHMS(Context context) {
super(context);
}
public MessageDigest getMessageDigest() {
MessageDigest messageDigest = null;
try {
messageDigest = MessageDigest.getInstance("SHA-256");
} catch (NoSuchAlgorithmException e) {
Log.e(TAG, "No Such Algorithm.", e);
}
return messageDigest;
}
public String getSignature(Context context, String packageName) {
PackageManager packageManager = context.getPackageManager();
Signature[] signatureArrs;
try {
signatureArrs = packageManager.getPackageInfo(packageName, PackageManager.GET_SIGNATURES).signatures;
} catch (PackageManager.NameNotFoundException e) {
Log.e(TAG, "Package name inexistent.");
return "";
}
if (null == signatureArrs || 0 == signatureArrs.length) {
Log.e(TAG, "signature is null.");
return "";
}
Log.e("hashhms =>", signatureArrs[0].toCharsString());
return signatureArrs[0].toCharsString();
}
public String getHashCode(String packageName, MessageDigest messageDigest, String signature) {
String appInfo = packageName + " " + signature;
messageDigest.update(appInfo.getBytes(StandardCharsets.UTF_8));
byte[] hashSignature = messageDigest.digest();
hashSignature = Arrays.copyOfRange(hashSignature, 0, 9);
String base64Hash = Base64.encodeToString(hashSignature, Base64.NO_PADDING | Base64.NO_WRAP);
base64Hash = base64Hash.substring(0, 11);
return base64Hash;
}
}
