C# Class BCrypt, Zetetic.Security

Public Methods

Method	Description
CheckPassword ( string plaintext, string hashed ) : bool	Check that a plaintext password matches a previously hashed one.
GenerateSalt ( ) : string	Generate a salt for use with the `BCrypt.HashPassword()` method, selecting a reasonable default for the number of hashing rounds to apply.
GenerateSalt ( int logRounds ) : string	Generate a salt for use with the BCrypt.HashPassword() method.
HashPassword ( string password, string salt ) : string	Hash a password using the OpenBSD bcrypt scheme.

Method	Description
CryptRaw ( byte password, byte salt, int logRounds ) : byte[]	Perform the central password hashing step in the bcrypt scheme.

Method	Description
Char64 ( char c ) : int	Look up the 3 bits base64-encoded by the specified character, range-checking against the conversion table.
DecodeBase64 ( string s, int maximumLength ) : byte[]	Decode a string encoded using BCrypt's Base64 scheme to a byte array. Note that this is _not_ compatible with the standard MIME-Base64 encoding.
EksKey ( byte data, byte key ) : void	Perform the "enhanced key schedule" step described by Provos and Mazieres in "A Future-Adaptable Password Scheme" (http://www.openbsd.org/papers/bcrypt-paper.ps).
Encipher ( uint block, int offset ) : void	Blowfish encipher a single 64-bit block encoded as two 32-bit halves.
EncodeBase64 ( byte d, int length ) : string	Encode a byte array using bcrypt's slightly-modified Base64 encoding scheme. Note that this is _not_ compatible with the standard MIME-Base64 encoding.
InitKey ( ) : void	Initialize the Blowfish key schedule.
Key ( byte key ) : void	Key the Blowfish cipher.
StreamToWord ( byte data, int &offset ) : uint	Cycically extract a word of key material.

Check that a plaintext password matches a previously hashed one.

public static CheckPassword ( string plaintext, string hashed ) : bool
plaintext	string	The plaintext password to verify.
hashed	string	The previously hashed password.
return	bool

Perform the central password hashing step in the bcrypt scheme.

protected CryptRaw ( byte password, byte salt, int logRounds ) : byte[]
password	byte	The password to hash.
salt	byte	The binary salt to hash with the /// password.
logRounds	int	The binary logarithm of the number of /// rounds of hashing to apply.
return	byte[]

Generate a salt for use with the BCrypt.HashPassword() method, selecting a reasonable default for the number of hashing rounds to apply.

public static GenerateSalt ( ) : string
return	string

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

public static GenerateSalt ( int logRounds ) : string
logRounds	int	The log2 of the number of rounds of /// hashing to apply. The work factor therefore increases as (2 ** /// logRounds).
return	string

Hash a password using the OpenBSD bcrypt scheme.

public static HashPassword ( string password, string salt ) : string
password	string	The password to hash.
salt	string	The salt to hash with (perhaps generated /// using BCrypt.GenerateSalt).
return	string
