我想了解通过 IAIK PKCS11Wrapper 生成 RSA 2048 位密钥之间的区别,我使用的是名为 的示例类GenerateKeyPair.java
,而 IAIK PKCS11Provider 也使用 IAIK PKCS11Wrapper 并通过名为 的示例类生成密钥对KeyPairGeneratorDemo.java
。
我正在使用带有 USB 令牌 ACS CryptoMate64 的上述库和类。
当我使用 PKCS11Wrapper 并加载我的 pkcs11.dll 时,一切正常。生成密钥对。
但是当我试图通过 IAIK PKCS11Provider 类做同样的事情时,它在尝试生成密钥对时抛出异常keyPair_ = keyPairGenerator.generateKeyPair();
:
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)
这两种方法有什么区别?为什么通过 IAIK PKCS11Provider 生成密钥对会抛出 CKR_ATTRIBUTE_VALUE_INVALID?我知道这个常数在 PKCS11 标准中意味着什么,但我不完全理解为什么当 IAIK PKCS11Wrapper 成功使用它时会抛出它......
我还附上了我正在使用的两个类。
