The Utils class provides a collection of utility methods that can be used for various purposes.

Usage

GenerateSalt

byte[] salt = Utils.GenerateSalt();

Generates a random salt byte array of the specified size.

Parameters:

• size (optional): The size of the salt array to generate, in bytes. Defaults to 128.

Returns:

• A byte array containing the randomly generated salt.

GetRandomHandler

uint random = Utils.GetRandomHandler();

Generates a random unsigned integer using the default random number generator.

Returns:

• A random unsigned integer.

HashPassword

string password = "myPassword";
byte[] salt = Utils.GenerateSalt();
string hashedPassword = Utils.HashPassword(password, salt);

Computes the hash value for the specified password using the specified salt and iteration count.

Parameters:

• password: The password to hash.
• salt: The salt to use for the hashing operation.
• iterationCount (optional): The number of iterations to perform. Defaults to 10000.
• numBytesRequested (optional): The size of the output hash, in bytes. Defaults to 256.

Returns:

• A string representation of the computed hash value.

RsaCryptoServiceProviderFromPemAsync

string filePath = "myPrivateKey.pem";
RSACryptoServiceProvider rsa = await Utils.RsaCryptoServiceProviderFromPemAsync(filePath);

Reads an RSA key pair from a PEM file asynchronously.

Parameters:

• filePath: The path of the PEM file to read.

Returns:

• A task that represents the asynchronous operation. The task result contains the RSA key pair.

Sha256Hash

string value = "myValue";
string sha256Hash = await Utils.Sha256Hash(value);

Computes the SHA256 hash value for the specified string asynchronously.

Parameters:

• value: The string to hash.

Returns:

• A task that represents the asynchronous operation. The task result contains the computed hash value.

Md5HashAsync

string value = "myValue";
string md5Hash = await Utils.Md5HashAsync(value);

Computes the MD5 hash value for the specified string asynchronously.

Parameters:

• value: The string to hash.

Returns:

• A task that represents the asynchronous operation. The task result contains the computed hash value.

Sha256HashFileAsync

string filename = "myFile.txt";
string sha256Hash = await Utils.Sha256HashFileAsync(filename);

Computes the SHA256 hash value for the specified file asynchronously.

Parameters:

• filename: The path of the file to hash.
• createChecksumFile (optional): True to create a checksum file, false otherwise. Defaults to true.

Returns:

• A task that represents the asynchronous operation. The task result contains the computed hash value.
