The algorithm uses a key pair consisting of a public key and a private key. The private key is used to generate a digital signature for a message, and such a signature can be verified by using the signer's corresponding public key.
The signer's public key consists of N and e, and the signer's secret key contains d. Used directly, this type of signature scheme is vulnerable to key-only existential forgery attack. To create a forgery, the attacker picks a random signature σ and uses the verification procedure to determine the message, m, corresponding to that signature. [32]
On 32-bit systems only, installing drivers that are not validated with Microsoft is possible after agreeing to allow the installation at a prompt warning the user that the code is unsigned. For .NET (managed) code, there is an additional mechanism called Strong Name Signing that uses Public/Private keys and SHA -1 hash as opposed to certificates.
DSC is the basis for Encapsulated PostScript (EPS): EPS files are documents that conform to the DSC standards with further restrictions. The set of DSC comments can be expanded by a mechanism called the Open Structuring Conventions, which, together with the EPS specification, form the basis of early versions of the Adobe Illustrator Artwork ...

For signing a message, the signer just sends a list of hash values (outputs of a hash function) to a publishing server and therefore the signature process is very fast, though the size of the signature is many times larger, compared to ordinary public-key signature schemes. 2.
