It defines the mathematical properties of public and private keys, primitive operations for encryption and signatures, secure cryptographic schemes. It provides the basic definitions of and recommendations for implementing the RSA algorithm for publickey cryptography.
This means that only the unique combination of that particular document and that particular signer can generate a particular digital signature.

An identical code cannot be generated by another signer for the same document or by the same signer for another document. A code generated for a particular document by a particular signer is unique. A Digital Signature is a sequence of ‘bytes’ or a code that has some special characteristics. For example, in India, Income Tax returns, corporate returns etc are to be digitally signed and uploaded electronically. Because of the higher security associated with Digital Signatures and the many advantages associated with storing documents electronically (as opposed to paper), governments in many countries have passed laws and regulations encouraging (and in some cases mandating) the usage of digitally signed electronic documents rather than paper documents. On the other hand, the technology behind Digital Signatures makes it virtually impossible to forge them. Physical signatures are easily replicated or ‘forged’. Digital Signatures are much more secure and ‘fool-proof’ compared to physical signatures. Just as a physical signature on a paper document establishes the origin of that document, a digital signature affixed to a digital document (computer file) establishes the origin of that digital document.
