大家好我得到這個錯誤，當我試圖複製和粘貼我生成的ssh2公鑰。java invalidKeyException
這裏是錯誤的完整堆棧跟蹤：

這裏是我使用的轉換爲字節數組

---- END SSH2 PUBLIC KEY ----
而且這裏的公共密鑰明文是代碼轉換爲字節數組並使用x509 keyspec
byte[] key = Base64.encodeBase64(publicKey.getBytes());
x509KeySpec = new X509EncodedKeySpec(key);
keyFactory = KeyFactory.getInstance("RSA");
return keyFactory.generatePublic(x509KeySpec);
它看起來像文本已經基地64編碼。你想要64位解碼該字符串來獲取字節。 – Aurand
我試圖解碼它，而仍然得到了錯誤 – jonney
