Asymmetric Encryption, often known as public-key cryptography, is a kind of encryption. This is because the encryption procedure uses two separate keys, one public and one private. The public key, as its name suggests, can be shared with everyone, while the private key must be kept private ...
What, then, is the difference between hashing and encrypting passwords? It's simple: with hashing, you have no way of reverting the hash value (the string that you get after hashing) back to plain text, whereas, with encryption, you have a key that can reverse the process. Let's delve...
The Hashtable and Dictionary classes in C# are both used for storing key-value pairs, but there are several differences between them in terms of functionality, performance, and usage. Type Safety The Dictionary class is type-safe, meaning that you specify the type of both the keys and values...
eventually, every hashing algorithm, including a secure one, produces a collision. But we are mostly concerned with how easy it would be to do so. SHA-1 was deemed insecure because, due to both its size and construction, it was feasible to produce a collision. ...
(cryptography) A randomly-generated value that is added to another value (such as a password) prior to hashing. Unlike a salt, a new one is generated for each value and it is held separately from the value. Pepper (transitive) To add pepper to. Pepper (transitive) To strike with somethi...
(cryptography) Randomly chosen bytes added to a plaintext message prior to encrypting or hashing it, in order to render brute-force decryption more difficult. Salt A person who seeks employment at a company in order to (once employed by it) help unionize it. Salt (obsolete) Flavour; taste...
Main Differences Between SHA-256 and SHA-1 SHA-256 is a cryptographic function with a newer, stronger, more advanced algorithm, whereas SHA-1 is a cryptographic function with an older algorithm. The SHA-256 algorithm requires a lot more space to store a hash value in memory or on a disk...
Elliptic curve cryptography (ECC)is another type of asymmetric encryption. Based on elliptic curve theory, ECC uses algebraic functions to generate security between key pairs. Asymmetric cryptography is used in key exchange, email and web security, and cryptocurrencies, such as bitco...
PGP, or Pretty Good Privacy, uses a combination of encryption methodologies such as hashing, data compression, symmetric-key cryptography, and public-key cryptography to keep data secure. PGP can be used to encrypt text files, emails, data files, directories, and disk partitions. Where did PGP...
