• The output value produced by a Hash Function, commonly formatted as hex or Base 64 Encoding
  • It is infeasible to reverse back the original text with the hash digest only

Vulnerable to Brute-force attacks

Can by hacked by Rainbow table - Wikipedia. You can try to hash of common text and hack using this website

One way to counter it is to use Salting

Common Hash Algorithms

MD5 (Message Digest)

  • A Hashing Algorithm that can be broken

SHA256 (Secure Hash Algorithm)

  • A Hashing Algorithm that produces a fix length of Digest that is 256-bits
# Output is hex encoded
