Which two categories of cryptographic algorithms are used for a digital signature?
Digital signatures primarily utilize two categories of cryptographic algorithms: hash functions and asymmetric (public-key) algorithms. Hash functions generate a fixed-size hash value from the data, ensuring integrity, while asymmetric algorithms, such as RSA or ECDSA, are used to encrypt the hash value with a private key, providing authentication and non-repudiation. Together, these components enable the secure signing and verification of digital messages or documents.

What is the procediour of verefing of digital signature on smartphoner?
To verify a digital signature on a smartphone, the user typically needs to have the public key associated with the signer. The verification process involves using a digital signature verification app or built-in functionality, where the user inputs the signed document and the public key. The app then checks the signature against the data using cryptographic algorithms to confirm its authenticity and integrity. If the signature is valid, it indicates that the document has not been altered and comes from a legitimate source.
Why Digital signature could not be verified?
A digital signature may not be verified for several reasons, including an invalid or expired certificate associated with the signature, a mismatch between the signed data and the hash value, or issues with the cryptographic algorithms used. Additionally, if the public key used for verification does not correspond to the private key that created the signature, the verification will fail. Network issues or tampered documents can also lead to verification failures.
What is the function of digital signature?
A digital signature serves as a secure and verifiable way to authenticate the identity of the sender and ensure the integrity of a digital message or document. It uses cryptographic algorithms to create a unique code that is generated from the content of the message and the sender's private key. This signature can be verified by the recipient using the sender's public key, confirming that the message has not been altered and that it originated from the claimed sender. Digital signatures are widely used in various applications, including emails, software distribution, and financial transactions, to enhance security and trust.

What do you mean by Digital Signatures and Digital Money?
This article is about cryptographic signatures. For simple signatures in digital form, see Electronic signature.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.
Who sign a digital certificate?
A Digital Signature Certificate, is a digital identity of the sender filing the documents through internet .Digital Signature Certificate is a digital equivalent of a hand written signature which has an extra data attached electronically to any message or a document.
What are the core elements of blockchain?
The core elements of blockchain technology include a distributed network of nodes, a consensus mechanism, cryptographic algorithms, and a digital ledger. The distributed network of nodes collectively validate and verify transactions, ensuring that no single node has control over the network. The consensus mechanism ensures that all nodes on the network agree on the state of the ledger and prevents double-spending or other malicious activities. Cryptographic algorithms are used to secure the data and ensure its integrity, making it resistant to tampering or hacking. Finally, the digital ledger records all transactions in a chronological and immutable manner, providing a permanent record of all activities on the network. Jai Infoway
What is the Digital Signature Act 1997?

How do you apply for digital signature certificate?
Digital signatures are easily accessed online. There are several websites that will walk you through the process of applying for and creating your digital signature.
What are some examples of black boxes?
Examples of black boxes include flight data recorders on airplanes, event data recorders in vehicles, and cryptographic algorithms in digital security systems. In general, a black box refers to a system or device that operates based on inputs and outputs without revealing its internal workings.
What is Digital Signature Standard?
A Digital Signature establishes the identity of the sender or signee electronically while filing documents through the Internet. The Ministry of Corporate Affairs (MCA) mandates that the Directors sign some of the application documents using their Digital Signature. Hence, a Digital Signature is required for all Directors of a proposed Company.
