This document discusses digital signatures and how they provide authentication, integrity, and non-repudiation for electronic documents. It explains that a digital signature is created by encrypting a hash of a message with the sender's private key. The recipient can then decrypt the signature using the sender's public key to verify their identity and confirm the message has not been altered. Digital signatures are commonly used for software distribution, financial transactions, and anywhere tampering detection is important. They allow for secure electronic communication and commerce by helping to prevent forgery over the internet.

Easy for the signer to sign a message
There is no point in having a digital signature scheme that involves the signer needing to use slow and complex operations to compute a digital signature.
Easy for anyone to verify a message
Similarly we would like the verification of a digital signature to be as efficient as possible.
Hard for anyone to forge a digital signature
It should be practically impossible for anyone who is not the legitimate signer to compute a digital signature on a message that appears to be valid. By “appears to be valid” we mean that anyone who attempts to verify the digital signature is led to believe that they have just successfully verified a valid digital signature on a message.
A digital signature is a mathematical scheme for demonstrating the authenticity of a digital message or document. A valid digital signature gives a recipient reason to believe that the message was created by a known sender, such that the sender cannot deny having sent the message (authentication and non-repudiation) and that the message was not altered in transit (integrity). Digital signatures are commonly used for software distribution, financial transactions, and in other cases where it is important to detect forgery or tampering.
Digital signatures are often used to implement electronic signatures, a broader term that refers to any electronic data that carries the intent of a signature, but not all electronic signatures use digital signatures. In some countries, including the United States, India, and members of the European Union, electronic signatures have legal significance.

Asymmetric encryption, also known as public-key cryptography, is a type of encryption that uses a pair of keys to encrypt and decrypt data.
The pair of keys includes a public key, which can be shared with anyone, and a private key, which is kept secret by the Owner.
The sender uses the recipient’s public key to encrypt the data. The recipient then uses their private key to decrypt the data.
Digital Signature:A digital signature is a mathematical technique used to validate the authenticity and integrity of a message, software, or digital document.
Digital signatures can provide evidence of origin, identity and status of electronic documents, transactions or digital messages.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

3. To authenticate the identity of the sender of a
message
The signer of a document, and
To ensure that the original content of the message
or document that has been signed is unchanged
4. ●Only the owner can create the digital signature,
hence it can be used to verify who created a
message
●Generally don't sign the whole message
(doubling the size of information exchanged), but
just a digest or hash of the message
●A hash function takes the message, and
produces a fixed size (typically 64 to 512 bits)
value dependent on the message
5. ●Digital Signature - a data string which associates
a message with some originating entity
●When using a digital signature, the data itself is
not encrypted, but a hash of the data is
encrypted with a private key. A hash (also
known as a digest) is a unique, fixed-length
mathematical value that is determined by the
content of the message
6. ●In 1976,Whitfield Diffie and Martin Hellman first
described the Digital Signature.
●In 1984, Shafi Goldwasser, Silvio Micali, and
Ronald Rivest became the first to define the
security requirements of digital signature
schemes.

●These are digital signatures of same person on different
documents
●Digital Signatures are numbers
●Same Length – 40 digits
●They are document content
10. ●A digital certificate is an electronic “document”
●or computer generated record that officially links
together the subscriber’s identification with the
corresponding public key.
●The certificate is digitally signed by the issuing
Certification Authority (CA ) to ensure the
certificate’s authenticity so that anyone in
possession of the CA’s public
key can verify the legitimacy of the certificate
11. ●Certificate authorities (CA’s) will provide a requestor
with someone’s public key contained in a certificate.
Information in the certificate will identify the public
key’s owner, and provide the name of the CA who
validated the identity and signed the identity to public
key binding. In this way it is possible to see that a
certificate serves as a kind of protective “container”
for the public key, protecting the integrity of its
binding to an owner and authenticating both the
binding and identity via the reputation (and trust) of
the signing CA.
12. Private Key – Used for making digital signature
Public Key – Used to verify the digital signature
13. ●If the sender wishes to prove to a recipient that
he or she is the source oftheinformation, the
sender uses his or her private key to digitally
sign a message (adigital signature).
14. ●The receiver of a digitally signed message uses
the sender’s public key to verify the signature so
that the receiver knows that the person
controlling the private key corresponding to the
public key sent the information, and that the
received information has not been altered since
it was signed.
15. ●A key generation algorithm that selects a private
key uniformly at random from a set of possible
private keys. The algorithm outputs the private
key and a corresponding public key.
●A signing algorithm which, given a message and
a private key, produces a signature.
●A signature verifying algorithm which given a
message, public key and a signature, either
accepts or rejects.
16. ●To provide Authenticity, Integrity and
Non-repudiation to electronic
documents
●To use the Internet as the safe and
secure medium for e-Commerce.
17. ●Authentication :-Although messages may often
include information about the entity sending a
message, that information may not be accurate.
Digital signatures can be used to authenticate
the source of messages. When ownership of a
digital signature secret key is bound to a specific
user, a valid signature shows that the message
was sent by that user. The importance of high
confidence in sender authenticity is especially
obvious in a financial
18. 1.Integrity :-In many scenarios, the sender and
receiver of a message may have a need for
confidence that the message has not been
altered during transmission. Although encryption
hides the contents of a message, it may be
possible to change an encrypted message
19. ●Putting the private key on a smart card
●Using smart card readers with a separate
keyboard
●Using digital signatures only with trusted
applications
21. ●Digital signatures are commonly used for
software distribution, financial transactions, and
in other cases where it is important to detect
forgery and tampering.
22. ●Hence We are conclude that to use digital
signature we can secure our information by
Private and public key.
● A digital signature is an electronic signature that
can be used to authenticate the identity of the
sender of a message or the signer of a
document,
