Re: How to do RSA-2048 Encryption

I would like to do the similar encryption in the iOS

KeyFactory keyFactory = KeyFactory.getInstance("RSA");

  RSAPublicKeySpec pubKeySpec = new RSAPublicKeySpec(modulus, pubExp);

  RSAPublicKey key = (RSAPublicKey) keyFactory.generatePublic(pubKeySpec);

  Cipher cipher = Cipher.getInstance("RSA/ECB/PKCS1Padding");

  cipher.init(Cipher.ENCRYPT_MODE, key);

  byte[] cipherData = cipher.doFinal(value.getBytes());

  strEncryInfoData = new String(org.apache.commons.codec.binary.Base64.encodeBase64(cipherData));
