HS-HASH

HS-HASH is a data hashing class that uses a secure hash algorithm and returns the hashed value of the entered string. For security reasons, you may want to store passwords in hashed form. This guards against the possibility that someone who gains unauthorized access to the database can retrieve the passwords of every user in the system. Hashing performs a one-way transformation on a password, turning the password into another String, called the hashed password. “One-way” means that it is practically impossible to go the other way - to turn the hashed password back into the original password.


Features:

  1. SHA 1
  2. SHA 256
  3. SHA 384
  4. SHA 512
  5. MD5 (Use MD5 only for compatibility with legacy applications and data).
  6. Generate a random cryptographic key using the RNGCryptoServiceProvider
  7. AES Encrypt and Decrypt
  8. Rijndael Encrypt and Decrypt
  9. And more
