我想使用id_rsa和id_rsa.pub为Java中的应用程序创建质询 - 响应登录系统。为此,我希望能够从id_rsa和id_rsa.pub构建PublicKey
和PrivateKey
。
直接方法是以通常解析文本文件的方式解析这些,然后手动构建适当的java.security数据结构,以便在客户端和服务器中进行签名和验证。
是否有直接摄取这些文件的标准库快捷方式?

我所知道的最接近和最简单的方法是使用The Legion of the Bouncy Castle Java API与此类似的东西 -
// Just for the public / private key files...
private static String readFileAsString(
String filePath) throws java.io.IOException {
StringBuilder sb = new StringBuilder(100);
BufferedReader reader = null;
try {
reader = new BufferedReader(new FileReader(
filePath));
int fileIn;
while ((fileIn = reader.read()) != -1) {
sb.append((char) fileIn);
}
} finally {
reader.close();
}
return sb.toString();
}
// Add the SecurityProvider and a Base64 Decoder (Once)
Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());
BASE64Decoder b64 = new BASE64Decoder();
// For the publicKey
String publicKeyString = readFileAsString(publicKeyFileName);
AsymmetricKeyParameter publicKey =
(AsymmetricKeyParameter) PublicKeyFactory.createKey(b64.decodeBuffer(publicKeyString));
// For the privateKey
String privateKeyString = readFileAsString(privateKeyFilename);
AsymmetricKeyParameter privateKey =
(AsymmetricKeyParameter) PrivateKeyFactory.createKey(b64.decodeBuffer(privateKeyString));
