What is a Salted Secure Hash Algorithm ? - Security Wiki (2024)
Salted secured hash algorithm helps protect password hashes against dictionary attacks by introducing additional randomness. Password hash salting is when random data – a salt – is used as an additional input to a hash function that hashes a password. The goal of salting is to defend against dictionary attacks or attacks against hashed passwords using a rainbow table.
To salt a password hash, a new salt is randomly generated for each password. The salt and the password are concatenated and then processed with a cryptographic hash function. The resulting output (but not the original password) is stored with the salt in a database.
Since salts do not have to be memorized by humans they can make the size of the rainbow table required for a successful attack prohibitively large. Since salts are different in each password, they also protect commonly used passwords or those who use the same password on several sites, by making all salted hash instances for the same password different from each other.

In cryptography, a salt is random data fed as an additional input to a one-way function that hashes data, a password or passphrase. Salting helps defend against attacks that use precomputed tables (e.g. rainbow tables), by vastly growing the size of table needed for a successful attack.

Commonly referred to as SCRAM, is a protocol used to support password based authentication. It is a revision to the previous CRAM protocol. Mutual authentication is established between the client and server through sharing salt that was generated on the server and an ic(iteration counter).
Secure Hash Algorithms, also known as SHA, are a family of cryptographic functions designed to keep data secured. It works by transforming the data using a hash function: an algorithm that consists of bitwise operations, modular additions, and compression functions.
Password salting is a technique to protect passwords stored in databases by adding a string of 32 or more characters and then hashing them. Salting prevents hackers who breach an enterprise environment from reverse-engineering passwords and stealing them from the database.
In cryptography, a pepper is a secret added to an input such as a password during hashing with a cryptographic hash function. This value differs from a salt in that it is not stored alongside a password hash, but rather the pepper is kept separate in some other medium, such as a Hardware Security Module.
Hashing is a one-way process that converts a password to ciphertext using hash algorithms. A hashed password cannot be decrypted, but a hacker can try to reverse engineer it. Password salting adds random characters before or after a password prior to hashing to obfuscate the actual password.
By salting the passwords with two random characters, even if two accounts use the same password, no one can discover this just by reading hashes. Salting also makes it extremely difficult to determine if a person has used the same password for multiple systems.
These techniques share a common purpose. But there are several differences between them as well. Encryption is about encoding data accessible with a key; hashing is about irreversible calculations. In salting, we add random data to the main information and make it more secure for storage.
Salting is the practice of adding random strings to passwords before hashing them for security. These random strings are unique to each password. Hashing involves using a special method called a hash function to transform information into a specific set of characters known as a hash value.
Salt Security protects the APIs that form the core of every modern application. Its patented API Protection Platform is the only API security solution that combines the power of cloud-scale big data and time-tested ML/AI to detect and prevent API attacks.
HMAC is a Message Authentication Code, which is meant for verifying integrity. This is a totally different kind of beast. However, it so happens that HMAC is built over hash functions, and can be considered as a "keyed hash" -- a hash function with a key. A key is not a salt (keys are secret, salts are not).
The only meaning is that you are adding something to your password before you hash it, similarly to adding salt to your meal :-) According to Ken Thompson, one of the first people to use the term in a book, it's related to the term "salting a mine", referring to gold mines.
The short answer is you most likely can't. If by “salt” you actually mean a block cipher IV, then you need the encryption key and need to know the encryption algorithm. This usually refers to storage of passwords. A salt is applied to the password then a cryptographically sound hash function executed.
SHA-256 is a general purpose hash and similar to MD5 it was designed to be fast which makes it a less than ideal choice for a password hashing. This hash is mainly provided for migration purposes or where login performance is very critical.
