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

RSADecryptorEngine object given a private key that will be
used for decrypting the ciphertext. The modulus must be a multiple of 8.
key - The private key that will be used to decrypt the data. The
private key is associated with the public key that was
used to encrypt 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
