You can do this with the Bouncy Castle Crypto APIs, https://www.bouncycastle.org .

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));

As far as adding things like name, email and password, you are referring to generating a certificate, which requires that a key pair is generated. Certificate types vary depending on usage, as does the means to generate them.

If you wish to truly secure communications, http://www.amazon.com/Applied-Cryptography-Protocols-Algorithms-Source/dp/0471117099/ is an important read, since poorly generated certificate and key exchanges are worse than no cryptography at all.
