The PKCS1SignatureSigner object can sign messages using the RSA PKCS#1 signature scheme.
We implemented the PKCS1 signing as per the PKCS #1 version 2.1 document.

Signed: This element is only accessible by signed clients. If you intend to use this element, please contact RIM to establish the necessary agreements that will allow you to have your COD files signed. Signing is only required for use on the device, development under the JDE can occur without signing the CODs.
Certicom: This element is part of the Certicom Cryptography APIs. The Certicom Cryptography APIs provide the tools you need, including ECC based algorithms, to integrate high performance data security into your applications, such as public key data encryption and decryption, digital signatures, and data authentication. Since the Certicom Cryptography API is already in the JDE, its use will remove the need for you to engage in time and resource intensive security integration so that you have lower development costs and a faster time to market. Use of the Certicom Cryptography API requires a license from Certicom. Please contact Certicom directly for more information on licensing fees and conditions.

Constructs an RSA PKCS1SignatureSigner object (version 2.0) signing object which uses the given digest.
Parameters:
key - The private key to use for signing.
useASN1 - A boolean that determines whether or not to ASN1-encode the digest before it is signed.
Set this to false for version 1.5 (which does not use ASN1) or true for version 2.0
(which does use ASN1).

Constructs an RSA PKCS1SignatureSigner (version 1.5 or 2.0) object that uses the given digest.
Parameters:
key - The private key to use for signing
digest - The digest to use to process the message. If digest is null, then
if useASN1 is set to true then a SHA1Digest is created, else a MD5Digest is created.
useASN1 - A boolean that determines whether or not to ASN1-encode the digest before it is signed.
Set this to false for version 1.5 (which does not use ASN1) or true for version 2.0
(which does use ASN1).
