Cryptographic salt

WebCryptography is defined as the practice and study of techniques of secure communication between two parties in the presence of a 3rd party. Encryption is a technique of cryptography wherein a message is encoded such that only authorized parties can read it, converting plaintext into an unintelligible series of letters/numbers. WebNov 14, 2024 · A cryptographic salt is additional input other than message itself for a hash function so that it prevents attacker from launching dictionary attacks . Usually the salt is stored along with the hash of say the password etc. Keyed Hashing is secret key is used as input for hashing along with message like HMAC .
