java.lang.Object | +--net.rim.device.api.crypto.RSAEncryptorEngine
Provides the RSA encryption functionality on a block by block basis. The block length is the size of the modulus, which must be a multiple of 8 bits.
A description of the RSA algorithm can be found in PKCS #1 version 2.1. We support this definition of RSA.

public RSAEncryptorEngine(RSAPublicKey key) throws CryptoTokenException, CryptoUnsupportedOperationException
RSAEncryptorEngine object given a public key that will be
used for encrypting the plaintext. The modulus must be a multiple of 8.
key - The public key associated with the private key that will
be used to decrypt the data.CryptoTokenException - Thrown when an error occurs with a crypto
token or the crypto token is invalid.CryptoUnsupportedOperationException - Thrown when a call is made to
an unsupported operation.Certicom Contact Information
