JAVA中的GPG加解密的一些使用填坑经验

第一个坑：生产上业务要求用的是子密钥加密文件。

@SuppressWarnings("unchecked")    public static PGPPublicKey readPublicKey(InputStream in)            throws IOException, PGPException {        

PGPPublicKeyRingCollection keyRingCollection = new PGPPublicKeyRingCollection(PGPUtil.getDecoderStream(in));            PGPPublicKey publicKey = null;
Iterator<PGPPublicKeyRing> rIt = keyRingCollection.getKeyRings();        

while (publicKey == null && rIt.hasNext()) {          

 PGPPublicKeyRing kRing = rIt.next();            

Iterator<PGPPublicKey> kIt = kRing.getPublicKeys();          

 while (publicKey == null && kIt.hasNext()) {              

 PGPPublicKey key = kIt.next();     &n
