我想獲得像這樣的公鑰。 java可以做到嗎?例如,我輸入姓名,電子郵件和密碼。所以Java生成它的公鑰和私鑰。這個公鑰的例子如何使用Java生成電子郵件以獲取公鑰和私鑰

你可以用Bouncy Castle Crypto APIs https://www.bouncycastle.org來做到這一點。

KeyPairGenerator keyGen = KeyPairGenerator.getInstance("RSA"); 
keyGen.initialize(1024); 
KeyPair key = keyGen.generateKeyPair(); 
PrivateKey priv = key.getPrivate(); 
PublicKey pub = key.getPublic(); 
String privateKey = new String(Base64.encode(priv.getEncoded(), 0,priv.getEncoded().length, Base64.NO_WRAP)); 
String publicKey1 = new String(Base64.encode(pub.getEncoded(), 0,pub.getEncoded().length, Base64.NO_WRAP)); 
String publicKey = new String(Base64.encode(publicKey1.getBytes(),0, publicKey1.getBytes().length, Base64.NO_WRAP)); 

至於添加名稱,電子郵件和密碼的東西,你指的是生成一個證書,這需要生成一個密鑰對。證書類型因使用情況而異,生成證書的方式也不同。

如果你希望真正保護通信,http://www.amazon.com/Applied-Cryptography-Protocols-Algorithms-Source/dp/0471117099/是一個重要的閱讀,因爲生成不良的證書和密鑰交換比根本沒有密碼更糟糕。

這有幫助嗎?如果有的話,請接受答案!乾杯。 –
