“PKCS#1 v2.0 encryption is usually called OAEP encryption” Where can I confirm it?
Category : Development Tools & Services

I heard that "PKCS#1 v2.0 encryption is usually called OAEP encryption".

I'll need some kind of "official" doc saying this before using it on my project. I'm trying to find it with no sucess. Any idea where can I find it?


(by the way, could anyone with more than 1500 reputation create the tag PKCS#1? Thanks!)

Encryption of Strings works, encryption of byte[] array type does not work
Category : Programming Languages

I am using the following LINK for encryption and tried it with Strings and it worked. However, since I am dealing with images, I needed the encryption/decryption process to happen with byte arrays. So I modified the code in that link to the following:

public class AESencrp {
private static final String ALGO = "AES";
private static final byte[] keyValue =

Are there valid reasons for using a hardware encryption device (e.g. USB encryption dongle/keystore) over using a software library?
Category : Development Tools & Services

If your application needs to encrypt/decrypt data (for various reasons), are there any reasons why you would use a hardware device (e.g. a USB encryption device - like a Marx CryptoBox) instead of using a software encryption library (like .net Cryptography or writing your own) and keep your keys in a safe key store?

I am looking for some objective views on this matter.

Encryption Product Keys : Public and Private key encryption
Category : Programming Languages

I need to generate and validate product keys and have been thinking about using a public/private key system.

I generate our product keys based on

a client name (which could be a variable length string)
a 6 digit serial number.

It would be good if the product key would be of a manageable length (16 characters or so)

I need to encrypt them at the b

Confused about encryption with public and private keys (which to use for encryption)
Category : Programming Languages

I am making a licensing system when clients ask my server for a license and I send them a license if they are permitted to have one.

On my current system I encrypt the license using a single private key and have the public key embedded into the client application that they use to decrypt the license. It works!

Others have told me that I should be encrypting with the pub
