Methods

GetHash(byte[])

Computes a SHA256 hash of the input byte array (salt must already be included if needed).

public static byte[] GetHash(byte[] input)

Parameters

input byte[]

The byte array to hash.

Returns

byte[]

GetHash(byte[], byte[])

Computes a SHA256 hash of the password bytes combined with salt bytes.

public static byte[] GetHash(byte[] passwordBytes, byte[] saltBytes)

Parameters

passwordBytes byte[]

The password byte array.

saltBytes byte[]

The salt byte array.

Returns

byte[]

GetHashAndSalt(byte[], out byte[], out byte[])

Generates a random 10-byte salt, combines it with the password bytes, and computes a SHA256 hash.

public static void GetHashAndSalt(byte[] passwordBytes, out byte[] hash, out byte[] saltBytes)

Parameters

passwordBytes byte[]

The password byte array.

hash byte[]

The computed hash output.

saltBytes byte[]

The generated salt output.

GetHashAndSalt(byte[], out byte[], out byte[], int)

Generates a random salt of specified length, combines it with the password bytes, and computes a SHA256 hash.

public static void GetHashAndSalt(byte[] passwordBytes, out byte[] hash, out byte[] saltBytes, int saltByteCount)

Parameters

passwordBytes byte[]

The password byte array.

hash byte[]

The computed hash output.

saltBytes byte[]

The generated salt output.

saltByteCount int

The number of random bytes for the salt.

GetHashString(string)

Computes a SHA256 hash of the input string and returns it as a UTF8 string.

public static string GetHashString(string text)

Parameters

text string

The input string to hash.

Returns

string

GetMd5Hash(string)

Computes an MD5 hash of the input text using UTF8 encoding.

public static string GetMd5Hash(string text)

Parameters

text string

The input text to hash.

Returns

string

GetMd5Hash(string, Encoding)

Computes an MD5 hash of the input text using the specified encoding.

public static string GetMd5Hash(string text, Encoding encoding)

Parameters

text string

The input text to hash.

encoding Encoding

The encoding to use for converting the text to bytes.

Returns

string

PairHashAndPassword(byte[], byte[], byte[])

Verifies that the password matches the stored hash by combining it with the salt and comparing.

public static bool PairHashAndPassword(byte[] hash, byte[] saltBytes, byte[] passwordBytes)

Parameters

hash byte[]

The stored hash to compare against.

saltBytes byte[]

The salt used in the original hash.

passwordBytes byte[]

The password bytes to verify.

Returns

bool
