RSA Public Key 与Sun RSA public key, 1024 bits params: null 区别 是什么?

RSA是一种非对称加密算法,公钥加密、私钥解密。在Java中,有两种不同的公钥格式:`RSA Public Key`和`Sun RSA public key`。
`RSA Public Key`是Java默认的公钥格式,它包含了公钥的模数和指数。而`Sun RSA public key`则是Sun公司自己实现的公钥格式,它包含了公钥的模数、指数以及加密算法的标识。
在实际应用中,两种公钥格式可以互相转换,但需要注意的是,不同的加密算法可能对应不同的标识,因此在转换时需要注意加密算法的一致性。

这两个问题都涉及到 RSA 加密算法中的公钥和私钥。
第一个问题中给出的是一个 RSA 公钥,其中包含了一个 1024 位的模数和一个公共指数。这个公钥可以用于加密数据,只有拥有对应的私钥的人才能解密。
第二个问题中给出的也是一个 RSA 公钥,但是它的表示形式略有不同。其中的模数和公共指数都是用十六进制字符串表示的。这个公钥也可以用于加密数据,只有拥有对应的私钥的人才能解密。
这两个问题中的公钥都是用不同的表示形式来描述同一个数学概念。它们之间的转换可以通过将十六进制字符串表示的模数和公共指数转换为十进制数,然后使用这些数来构造一个新的 RSA 公钥对象。同样地,可以将一个 RSA 公钥对象转换为十六进制字符串表示的模数和公共指数。这些转换可以使用编程语言中的特定函数来完成。
rsa public key not find
If you are trying to encrypt a message using RSA public key encryption and you are getting an error that says "RSA public key not found", it could mean that the public key you are trying to use does not exist or cannot be accessed. Here are some possible reasons and solutions:
1. The public key file is missing or in the wrong location. Check that the file exists and is in the correct directory.
2. The public key file has the wrong permissions. Make sure that the file has read permissions for the user running the encryption process.
3. The public key file is corrupted or unreadable. Try re-generating the public key or obtaining a new copy.
4. The public key is not stored in the correct format. Make sure that the key is in a valid RSA public key format, such as PEM or DER.
5. The public key is not associated with the correct private key. Make sure that the public key corresponds to the private key used for decryption.
If none of these solutions work, you may need to seek further assistance or consult the documentation for the encryption software you are using.
