UWP RSA

正确示例：

var loginPBK = "";//your public key,such as "MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCp0wHYbg......."
var provider = AsymmetricKeyAlgorithmProvider.OpenAlgorithm(AsymmetricAlgorithmNames.RsaPkcs1);
var publicKey = provider.ImportPublicKey(CryptographicBuffer.DecodeFromBase64String(loginPBK));
var encryptData = CryptographicEngine.Encrypt(publicKey, CryptographicBuffer.ConvertStringToBinary(password, BinaryStringEncoding.Utf8), null);
var pwd2 = CryptographicBuffer.EncodeToBase64String(encryptData);

　　Tip:ImportPublickKey指定加密方式时，会导致ASN1 bad tag value met
