RSA Keys distributed

[K ridley]

Im using Bouncy Castle lightweight and WTK 2.2. My problem is that Im receiving a Hex-encoded RSA public key, that I should like to use for decrypting a message.

Is there anyway to contruct a :

org.bouncycastle.asn1.x509.RSAKeyParameters by just having a byte[]/hex string of the entire key?

Best Regards

K.
