Introduction
Cryptography is the science of coding and decoding information. In today’s world, cryptography has many applications, which include (but are not limited to) ATM cards, computer passwords, encryption key management and secure internet communications.

Cryptography is the art and science of writing and solving codes. It’s used to keep information secure, whether it’s stored on your computer or sent over the internet. Cryptography has applications in many areas, including computer security and online communications (for example, when you use HTTPS).
The very first known use of cryptography dates back to 2400 BC, when in the Egyptian empire.
The very first known use of cryptography dates back to 2400 BC, when in the Egyptian empire. This was done by using hieroglyphs to keep messages secret from others.
The hieroglyphs had no meaning until you knew how they were used and what they meant; they were just symbols that could be understood only by those who knew how to read them. The same way as cryptography works today!
This is why cryptography has been around for thousands of years and was used even before computers were invented!
In modern times, cryptography has many applications, which include (but are not limited to) ATM cards, computer passwords, encryption key management and secure internet communications.

Cryptography is the art of writing and solving codes. It has been around for thousands of years in various forms such as ciphers or secret codes used by the military to send messages without being intercepted by enemies. Today, there are two main types of cryptography: symmetric-key cryptography (also known as private-key cryptography) and public-key cryptography (also known as public-private keypair).
The aim of cryptography is to hide information so that it can only be accessed by someone who knows how to get at that information.
Cryptography is the science of encoding and decoding information. It can be used to protect data in transit, data at rest and data in use. Cryptography can also be used to verify the authenticity of data.
The aim of cryptography is to hide information so that it can only be accessed by someone who knows how to get at that information.
Cryptography uses three basic principles; confidentiality, integrity and authenticity.
Cryptography uses three basic principles; confidentiality, integrity and authenticity. Confidentiality means that the information is not available to anyone who does not have the key. Integrity means that the information is correct and has not been tampered with. Authenticity means that the information has not been altered by anyone other than the sender
Cryptographic mechanisms usually involve two parties (or more), an encryption algorithm and an agreed-upon key for use with that algorithm.
The concept of cryptography involves two parties, an encryption algorithm and an agreed-upon key for use with that algorithm. The key is used to decrypt data that has been encrypted by the encryption algorithm.
Cryptography uses a combination of these tools to achieve confidentiality (keeping messages private), integrity (making sure messages aren’t modified in transit) and authenticity (making sure messages are from whom they claim).
Cryptography involves several processes such as encryption or decryption which may require keys and specific algorithms to achieve these processes.

Cryptography uses three basic principles; confidentiality, integrity and authenticity:
Confidentiality refers to keeping data secret from unauthorized users; this principle ensures that only authorized people can access information stored in a database or on the internet etcetera..
Integrity means making sure that no one modifies any part of the original message without being detected by others who have access (or could otherwise discover) what has been changed – for example when sending an email over an insecure network such as WiFi where there could be other people nearby trying out tricks like ‘packet sniffing’ – when someone tries capturing packets sent over wireless networks using software designed specifically for this purpose! This would allow them see everything you send before it arrives at its destination.”
In blockchain technology, the process of encryption involves generating a public key from a private key using an algorithm known as Elliptic Curve Digital Signature Algorithm (ECDSA).
In blockchain technology, the process of encryption involves generating a public key from a private key using an algorithm known as Elliptic Curve Digital Signature Algorithm (ECDSA). The public key is used to encrypt data and verify signatures on transactions, whereas the private key decrypts information.
A hash function is used to generate a digital signature for each transaction that takes place on the blockchain network. This ensures authenticity, integrity and non-repudiation of transactions carried out on the network. A hash function takes input data of any length (eg: “hello world”) and returns output data of fixed length (eg: “2f9cfc78d6b1b6e3a74626c6d8e86713″). If you change even one bit in your input message then there will be no matching output message after applying this transformation algorithm again because it will produce completely different outputs every time with no possibility for two different inputs producing same output values without any tampering having occurred during transmission between sender/receiver parties involved in sending/receiving messages over internet connections which might lead us believe we’re communicating securely but actually aren’t due some malicious third party intercepting messages sent between two parties without them knowing about it until later when damage has already been done!”
Understanding cryptography will help you understand blockchain technology better!
Blockchain technology is a type of distributed ledger technology (DLT). In simple terms, it’s an electronic database that has been shared between multiple parties and updated regularly. The database is made up of blocks containing information and data related to transactions conducted within the network, as well as timestamps for each transaction recorded in the block. These blocks are then linked together using cryptographic hash functions to create a chain – hence the name “blockchain.”
The use of cryptography ensures that the data stored on a blockchain cannot be altered without everyone involved knowing about it; this makes them ideal for recording financial transactions or other sensitive data where authenticity is important. Cryptography also provides privacy protection: only authorized users can access sensitive information such as passwords or PIN numbers used during login processes via public key cryptography techniques such as RSA encryption (Rivest Shamir Adleman), which uses two mathematically related keys — one private key known only by its owner (usually referred to by its nickname “secret key”) while another public key acts as an alias for this secret key when transmitting messages over insecure channels like internet chatrooms etcetera…
Conclusion
In conclusion, we have seen that cryptography is a very important part of blockchain technology. The process of encryption involves generating a public key from a private key using an algorithm known as Elliptic Curve Digital Signature Algorithm (ECDSA).
