On the one hand, I hear people saying that the two keys are totally interchangeable, the first one will decrypt what the second one encrypted. This makes me think that the two keys are interchangea...

I have the byte array of the RSA Public Key. I found on the internet that I can create a real PublicKey object of it by using this code: PublicKey publicKey = KeyFactory.getInstance("RSA").gener...

This is my first post, so hope I haven't missed anything important. I'm doing a project in C# where I need to use public/private key encryption to encrypt a message and then send it over an SSL con...

I'm just starting to learn XML security. We have VS-2005 & ASP.Net 2.0. I want to send XML to a outside URL and it needs to be encrypted. I'm doing exactly what the MSDN articles ms229744 &...

i am using a certificate generated by makecert which has both private and public key. The java side uses this public key to encrypt the data and .net decrypts it back. I am trying to decrypt Java'...

This is my first question on this site, and I only have a basic mathematical understanding of RSA, so please bear with me! :) I'm writing a Java web application for my final year project at univer...

The Situation I'm working with RSA encryption in Java. I'm trying to encrypt data on an HTC Saphire (32B) developer phone equipped with Cyanogenmod's Android 2.2 and then decrypt said data on a 64...

I'm looking for two functions conceptually similar to these: // returns the encrypted text string encrypt( string public_key, string pass_phrase, string text ); // returns the original text string...

I'm looking for a Delphi implementation of an asymmetric encryption algorithm without any dependencies on external DLLs. Is there any available? My goal is to encrypt/decrypt a string (or array of...

I have an exam tomorrow in Advanced Development, but I am stuck on the topic of Encryption. I have read up on it at http://support.microsoft.com/kb/246071. However I am still confused. If a messag...

I need to encrypt a 100KB file using a public key. I've been reading some posts claiming that it is not practical to directly encrypt large files using a public key, and that the preferred method i...

This code generates a pair of public/private keys: KeyPairGenerator keyGen = KeyPairGenerator.getInstance("RSA"); keyGen.initialize(1024); KeyPair keypair = keyGen.genKeyPair(); PrivateKey private...

I would like to ask if i can use Asymmetric Crypto (like RSA or ECC) on android mobile phones, how, and what are the best libraries i should use.

Is it possible to get additional security by encrypting a message using 2 or more RSA keys? EDIT: A few clarifications: The context I am most interested in doing this for is encrypting a randomly...

I am encrypting on JAVA using RSA and attempting to decrypt using .NET. I am including my JAVA code and .NET code in hopes that someone has some experience with this sort of thing. JAVA Code: by...

I've the task to transfer small binary messages (1 or 2 kb long) between a desktop application and mobile devices. The messages should be encrypted asymmetrically (RSA for instance). From what I've...

I think I know how to create custom encrypted RSA keys, but how can I read one encrypted like ssh-keygen does? I know I can do this: OpenSSL::PKey::RSA.new(File.read('private_key')) But then Op...

I have a database that contains sensitive information. I can encrypt / decrypt the data on the read write operations. The problem is that I need to store the key in the application. If someone has ...

I've been able find information on symmetric encryption and hashing but I've been having quite a bit of trouble finding much information on any sort of public key encryption for java. What I'...
