A hash table is a large list of pre-computed hashes for commonly used passwords. For a password file without salts, an attacker can go through each entry and look up the hashed password in the hash table or rainbow table. If the look-up is considerably faster than the hash function (which it often is), this will considerably speed up cracking
Difference Between Hashing and Encrypting | Compare the Jun 25, 2011 Encryption vs Hashing · Ramblings of a Unix Geek Encryption and hashing may both be cryptographic in nature, but there’s a subtle difference between them. Encryption This process is reversible ; someone with the right knowledge could take the cipher text (as the encoded data is known) and decrypt it back to the original plain text. Difference between Encryption, Encoding and Hashing
A hash function maps some data to other data. It is often used to speed up comparisons or create a hash table. Not all hash functions are secure and the hash does not necessarily changes when the data changes. A cryptographic hash function (such as SHA1) is a checksum that is secure against malicious changes. It is pretty hard to create a file

Difference between Encryption, Encoding and Hashing Encryption, encoding and hashing are techniques used for converting the format of data. Encryption is used for changing plain text into cipher text so that only authorized entities can understand it. Encoding is used for changing the data into a special format which makes it usable by external processes. In hashing, the data is converted to a message digest or hash, which is Encrypted hash vs hashed encryption - Cryptography Stack
