The BlowfishCipher type exposes the following members.
Methods
| Name | Description | |
|---|---|---|
 | BCrypt |
Uses the cipher to generate a BCrypt hash.
|
 | BCrypt(Byte, Byte, Int32) |
Uses the given key, salt, and cost to generate a BCrypt hash.
|
| BCrypt(Byte, Byte, Int32, EksBlowfishKeyExpansionFlags) |
Uses the given key, salt, and cost to generate a BCrypt hash.
Flags may modify the key expansion.
|
| Create |
Creates a Blowfish cipher using the provided key.
|
| CreateEks(Byte, Byte, Int32) |
Performs an Expensive Key Schedule (EKS) Blowfish key expansion and
creates a Blowfish cipher using the result.
|
| CreateEks(Byte, Byte, Int32, EksBlowfishKeyExpansionFlags) |
Performs an Expensive Key Schedule (EKS) Blowfish key expansion and
creates a Blowfish cipher using the result. Flags may modify the key expansion.
|
| Decipher(Byte, Int32) |
Reverses the encipherment of eight bytes of data in-place.
|
| Decipher(UInt32, UInt32) |
Reverses the encipherment of eight bytes of data.
|
| Decipher(Byte, Int32, Byte, Int32) |
Reverses the encipherment of eight bytes of data from one buffer and places the result in another buffer.
|
| Dispose |
Clears all memory used by the cipher.
|
| Encipher(Byte, Int32) |
Enciphers eight bytes of data in-place.
|
| Encipher(UInt32, UInt32) |
Enciphers eight bytes of data.
|
| Encipher(Byte, Int32, Byte, Int32) |
Enciphers eight bytes of data from one buffer and places the result in another buffer.
|
Properties
| Name | Description | |
|---|---|---|
 | BCryptLength |
The number of bytes returned by BCrypt.
|
| BCryptMagic |
The special string used encrypted in the BCrypt algorithm.
|
| IsKeyWeak |
A Blowfish key is weak if one of its S-boxes has a duplicate entry.
