Public Key Cryptography

Tags: PKC, Public-Key Cryptography, Public-Key Encryption

Public Key Cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys. Each key pair consists of a public key and a corresponding private key.

The Future of Cryptography

Tags: Cryptography, Latest Trends

In today's digital age, cryptography plays a vital role in safeguarding our data and online interactions. As technology evolves, so too do the threats we face. This necessitates a continuous advancement in cryptographic techniques.

What does Encryption mean?

Tags: Encryption, Cryptography, Cryptology

In cryptography, encryption is the process of transforming (more specifically, encoding) information in a way that, ideally, only authorized parties can decode. This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext.

What is a Blockchain?

Tags: Blockchain, Cryptography, Distributed Ledger, Decentralized Ledger

A blockchain is a distributed ledger with growing lists of records (blocks) that are securely linked together via cryptographic hashes.

What is a Digital Signature?

Tags: Digital Signature, Digital Signature Scheme, Cryptography

A digital signature or digital signature scheme is a type of asymmetric cryptography that is used for identification of users on digital media. For messages sent through an insecure channel, a good implementation of a digital signature algorithm makes the receiver believe that the message was sent by the claimed sender, and trust the message.

What is a Zero Trust Architecture?

Tags: ZTA, Cryptography

Zero Trust Architecture, also known as Zero Trust Security Model is a security approach that moves away from the traditional 'castle and moat' mentality. In the old ways of thinking, everything inside the company network was trusted, while everything outside was suspect. ZTA flips this concept on its head.

What is Bitcoin?

Tags: Bitcoin, Cryptocurrency

Bitcoin is the first decentralized cryptocurrency. Nodes in the peer-to-peer Bitcoin network verify transactions through cryptography and record them in a public distributed ledger, called a blockchain, without central oversight.

What is Cryptography?

Tags: Cryptography, Cryptology

Cryptography is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages.

What is MD5?

Tags: Cryptography, MD5, Encryption, Message-Digest Algorithm

The MD5 message-digest algorithm is a widely used hash function producing a 128-bit hash value. MD5 was designed by Ronald Rivest in 1991 to replace an earlier hash function MD4, and was specified in 1992 as RFC 1321.
