​
Overview

The HelperCryptography class provides static methods for encrypting and hashing content using SHA512 and SHA1 algorithms. This helper is used for secure password storage and basic text encryption. Namespace: MvcCoreUtilidades.Helpers

​
Properties

​
Salt

public static string Salt { get; set; }
Static property that stores the current salt value used for encryption. This salt is automatically generated when encrypting content and should be stored alongside encrypted data for comparison operations.

​
Methods

​
CifrarContenido

public static string CifrarContenido(string contenido, bool comparar)
Encrypts content using SHA512 hashing with a salt. The method applies 12 iterations of hashing for enhanced security.
​
contenido
string
required
The content to be encrypted
​
comparar
bool
required
If false, generates a new salt. If true, uses the existing salt value from the Salt property for comparison purposes
Returns: string - The encrypted content as a Unicode string Usage: 
// Encrypting new content
string encrypted = HelperCryptography.CifrarContenido("myPassword", false);
string salt = HelperCryptography.Salt; // Save this for later comparison

// Comparing with existing salt
HelperCryptography.Salt = savedSalt;
string comparison = HelperCryptography.CifrarContenido("inputPassword", true);

​
EncriptarTextoBasico

public static string EncriptarTextoBasico(string contenido)
Performs basic text encryption using SHA1 hashing algorithm without salt.
​
contenido
string
required
The content to be encrypted
Returns: string - The encrypted content as a Unicode string Usage: 
string encrypted = HelperCryptography.EncriptarTextoBasico("textToEncrypt");

​
Implementation Details

  • Salt Generation: When comparar is false, a random 30-character salt is generated using ASCII characters (1-255)
  • SHA512 Hashing: The CifrarContenido method applies SHA512 hashing 12 times for increased security
  • SHA1 Hashing: The EncriptarTextoBasico method applies SHA1 hashing once
  • Encoding: All methods use Unicode encoding for string conversions
