Salt biography, Salt discography
In cryptography, a salt comprises random bits that are used as one of the inputs to a key derivation function.The other input is usually a password or passphrase.The key derivation function typically uses a hash function.Each bit of salt used doubles the amount of storage and computation required.The salt value is sometimes kept secret.This provides an advantage when a password database is stolen, but the salt is not.Rather, they must calculate the hashes of random characters (at least for the portion of the input they know is the salt), which is much slower.In some protocols, the salt is transmitted as cleartext with the encrypted data, sometimes along with the number of iterations used in generating the key (for key strengthening).Cryptographic protocols that use salts include SSL and Ciphersaber.Salt is closely related to the concept of nonce.The benefit provided by using a salted password is this: A simple dictionary attack against the encrypted values becomes impractical if the salt is large enough.That is, an attacker would not be able to create a rainbow table, a dictionary of encrypted values (password + salt) because it would either take too much time, or too much space.This would force the attacker to use the provided authentication mechanism (which "knows" the correct salt value).Even though the password itself is known to be simple, the secret salt makes breaking the password radically more difficult.Note that in Unix, the salt is also stored in the passwd file (as cleartext) together with the hash of the salted password.In such installations, the "root" account on each individual system may be treated as less "trusted" than the administrators of the centralized password system, so it remains worthwhile to ensure that the security of the password hashing algorithm, including the generation of unique "salt" values, is adequate.Salts also help protect against rainbow tables as they, in effect, extend the length and potentially the complexity of the password.If the rainbow tables do not have passwords matching the length (e.Without salts, an attacker who is cracking many passwords at the same time only needs to hash each password guess once, and compare it to all the hashes.However, with salts, all the passwords will likely have different salts; so each guess must be hashed separately for each salt, which is much slower since hashing is usually very computationally expensive.Another (lesser) benefit of a salt is as follows: two users might choose the same string as their password.Without a salt, this password would be stored as the same hash string in the password file.This would disclose the fact that the two users have the same password, allowing each user to access the other's account.By salting the password hashes with two random characters, even if two users choose the same password, odds are that they cannot discover that they have done so by reading the passwd file.This page was last modified on 26 April 2008, at 01:21.See Commercial questions about salt

for cooking, and sea salt for
table use.They claim that both have a softer flavor than table
salt.Exotic salts
include the expensive French and Hawaiian sea salts, the smoky, sulfuric Indian black salt,
and the intensely salty Korean bamboo salt.Adding salt to water will raise the temperature at which it boils and
lower the temperature at which it freezes.Though we need some salt in our diet, most Americans consume much more
than necessary.Too much salt can lead to high blood pressure.Salt is a terrific flavor enhancer, helping to reduce bitterness and
acidity, and bringing out other flavors in the food.Adding salt to bread dough controls the action of the yeast and improves
the flavor.Bread made without salt will have a coarser texture and
a blander flavor than bread made with salt.Try sprinkling salt on citrus fruit, melons, tomatoes, and even wine to
enhance flavor.Adding a little salt balances the flavor of sweets like cakes, cookies,
and candies.Boiling eggs in salted water makes them easier to peel.Salt is a mineral, so it can be stored indefinitely without going
stale.It won't taste any fresher if you grind it with a salt
mill.Salt has been used for millennia as a preservative for meats, fish,
cheese, and other foods.Salting slices of eggplants helps draw out the bitter
juices.OR kelp powder OR omit (Reducing salt in a recipe
reduces sodium, but doing so may impair flavor and, in the case of baked goods, texture.Since salt enhances flavorings, use more of them if you reduce salt in a recipe.This is made by roasting sea
salt in bamboo cylinders plugged with yellow mud.The salt absorbs minerals from the bamboo
and mud, which in turn leach the salt of impurities.Look
for plastic bags of it in Korean markets.Look for this in Indian markets, either ground or in lumps.This salt has extremely fine
grains.It's used to salt butter.Kosher salt and sea salt often come coarsely ground.This is salt that's been ground into small grains.This is used to cure meats and fish.It's usually dyed pink so that it won't be mistaken for ordinary salt.French salt comes from sea water that's pooled into basins and
then evaporated.Unlike most American sea salts, it's unrefined, so
it retains more of the minerals that naturally occur in seawater.La fleur de sel
(the flower of the salt) is whiter, but has a similar flavor.French sea salt drives chemists crazy, since almost all
of it is just plain salt, sodium chloride, NaCl.French sea salt has a much softer and fresher flavor than
ordinary table salt, and that the difference is worth it.These salts comes either coarsely or finely ground.It's best to use these salts after
the food is cooked, or their subtleties will be lost.The clay also imparts a subtle flavor to the salt.This salt was developed
for the preparation of kosher meats, but many cooks prefer it over table salt.This helps the salt adhere better, so it's great for lining margarita
glasses, and for making a salt crust on meats or fish.Kosher salt also is
preferred over table salt for canning and pickling.This raises the risk that the salt won't be properly measured.To get around this problem, measure by weight instead
of volume.With its large grains, kosher salt isn't a good choice
for baking.Look for boxes of it in the spice section of
your supermarket.This is used to
salt the rims of Margarita glasses.To apply, fill a saucer with the
salt, then moisten the rim of an empty glass with lime juice and dip it into the
saucer.OR sea salt OR table
salt OR sugar (This is the
preferred rim liner for fruit Margaritas.Pickles made with table salt would still be good to eat, but they
wouldn't look as appetizing.Pickling salt is available in
large bags or boxes in supermarkets, but it's hard to find in cities.To prevent lumps, put a few grains of rice in
your salt shaker.To get rid of lumps, spread the
salt on a cookie sheet and bake in an oven.Since it's not as dense as pickling salt, you'll
need to use more, but how much more varies by brand.The salt lowers the
freezing point of the ice, which causes it to melt.As it melts, it
absorbs heat from the ice cream, helping it to freeze more quickly.Use a
ratio of one part rock salt for every five parts of ice.If you're out of rock salt, other kinds of salt will
also work, though you should use less
since finer grains of salt can can be packed
more densely into a cup than large chunks of rock salt.The biggest
danger is that you'll use too much salt, which will make your ice cream freeze
too fast and become crusty.When using salt other than rock salt, start with a modest amount and check the ice cream after you've churned it
for ten minutes.If the ice cream is just beginning to firm up, you have
the right amount of salt.If it's not yet firming up, you need to add more
salt.If it's crusty along the sides of the bucket, then you've
added too much salt.Internet abounds with recipes for homemade salt
substitutes.Look for them in the spice
section of your supermarket, or in pharmacies.This salt comes from evaporated sea water, and contains minute amounts of
magnesium, calcium, and other minerals.United States contain at
least 97.French sea salts have higher concentrations.To prevent the cloudiness,
use pickling salt, which contains no additives.Kosher salt (This is more flavorful, and great
for cooking.Since it's less dense, grind it first or use up to twice as much.EPSS), interactive multimedia, instructional design, knowledge management systems (KM),
Learning Resource Center (LRC), online learning, and web based training.It enables one to achieve knowledge for work in the field
of applied learning technology by association with other professionals in conferences
