关于加密问题， key 生成不一样

This topic created in 3094 days ago, the information mentioned may be changed or developed.

KeySpec keySpec = new PBEKeySpec("password".toCharArray(), "LdWxmFbFiVZRRshf57i".toCharArray(),
100 , 256);
SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");
byte[] keyBytes = keyFactory.generateSecret(keySpec).getEncoded();

类似上面的代码
keyBytes 生成的怎么会不一样，哪里出错了吗

keyspec

keybytes

生成
