Class BCrypt

Namespace

PolarStudioGlobals

Assembly

PolarStudioGlobals.dll

This class is a helper for the BCrypt algoritm to securely store password hashes. This algorithm is using a big number of hashing actions, making it compute-intensive. This makes it harder to brute-force a password-hash.

Methods

CheckPassword(string, string)

Check that a plaintext password matches a previously hashed one.

public static bool CheckPassword(string plaintext, string hashed)

Parameters

plaintext string

The plaintext password to verify.

hashed string

The previously hashed password.

Returns

bool

true if the passwords, false otherwise.

DefaultLog2Rounds()

Returns the default number of hashes. Is logarithmic, so a value of 13 means 8192 hashes. 14 would cause 16384 hashes. etc.

public int DefaultLog2Rounds()

Returns

int

GenerateSalt(int)

Generate a salt for use with the BCrypt.HashPassword() method.

public static string GenerateSalt(int logRounds = 13)

Parameters

logRounds int

The log2 of the number of rounds of hashing to apply. The work factor therefore increases as (2 ** logRounds).

Returns

string

An encoded salt value.

HashPassword(string, int)

Hash a password using the OpenBSD bcrypt scheme.

public static string HashPassword(string password, int pLogRounds)

Parameters

password string

The password to hash.

pLogRounds int

The number of LogRounds to use. Is logarithmic. Higher numbers cause longer compute times.

Returns

string

The hashed password.

HashPassword(string, string)

Hash a password using the OpenBSD bcrypt scheme.

public static string HashPassword(string password, string salt = "")

Parameters

password string

The password to hash.

salt string

The salt to hash with (perhaps generated using BCrypt.GenerateSalt).

Returns

string

The hashed password.
