我想了解通過IAIK PKCS11Wrapper（其中我使用示例類GenerateKeyPair.java）和IAIK PKCS11Provider生成RSA 2048位密鑰之間的區別，它也使用IAIK PKCS11Wrapper並通過生成密鑰對示例類名爲KeyPairGeneratorDemo.java。IAIK PCKS11Provider VS IAIK PKCS11包裝密鑰生成
我使用上面的庫和類與USB令牌ACS CryptoMate64。
當我使用PKCS11Wrapper並加載我的pkcs11.dll一切正常。密鑰對被生成。
但是，當我試圖做通IAIK PKCS11Provider類相同，則拋出試圖生成密鑰對keyPair_ = keyPairGenerator.generateKeyPair();時異常：
Exception in thread "main" iaik.pkcs.pkcs11.provider.IAIKPkcs11Exception: iaik.pkcs.pkcs11.wrapper.PKCS11Exception: CKR_ATTRIBUTE_VALUE_INVALID
at iaik.pkcs.pkcs11.provider.keypairgenerators.PKCS11KeyPairGenerator.generateKeyPair(Unknown Source)
at java.security.KeyPairGenerator$Delegate.generateKeyPair(KeyPairGenerator.java:650)
at KeyPairGenerationDemo.generateKeyPairSimple(KeyPairGenerationDemo.java:114)
at KeyPairGenerationDemo.main(KeyPairGenerationDemo.java:91)
什麼是這兩種方法之間的區別？爲什麼通過IAIK PKCS11Provider生成密鑰對提交CKR_ATTRIBUTE_VALUE_INVALID？我知道PKCS11標準中的常量是什麼意思，但我不完全明白爲什麼當IAIK PKCS11Wrapper成功時，爲什麼會拋出這個錯誤...
我還附加了兩個我正在使用的類。
