Methods

  NameDescription
Public methodCanCrypt
Checks if the particular crypt algorithm is compatible with the salt string or crypted password.
(Overrides CrypterCanCrypt(String).)
Public methodCrypt(Byte)
Creates a one-way password hash (crypted password) from password bytes.
(Inherited from Crypter.)
Public methodCrypt(String)
Creates a one-way password hash (crypted password) from a password string.
(Inherited from Crypter.)
Public methodCrypt(Byte, String)
Creates a one-way password hash (crypted password) from password bytes and a salt string. The salt can be produced using GenerateSalt(CrypterOptions). Because crypted passwords take the form algorithm+salt+hash, if you pass a crypted password as the salt parameter, the same algorithm and salt will be used to re-crypt the password. Since randomness comes from the salt, the same salt means the same hash, and so the same crypted password will result. Therefore, this method can both generate *and* verify crypted passwords.
(Overrides CrypterCrypt(Byte, String).)
Public methodCrypt(Byte, CrypterOptions)
Creates a one-way password hash (crypted password) from password bytes. Options modify the crypt operation.
(Inherited from Crypter.)
Public methodCrypt(String, CrypterOptions)
Creates a one-way password hash (crypted password) from a password string. Options modify the crypt operation.
(Inherited from Crypter.)
Public methodCrypt(String, String)
Creates a one-way password hash (crypted password) from a password string and a salt string. The salt can be produced using GenerateSalt(CrypterOptions). Because crypted passwords take the form algorithm+salt+hash, if you pass a crypted password as the salt parameter, the same algorithm and salt will be used to re-crypt the password. Since randomness comes from the salt, the same salt means the same hash, and so the same crypted password will result. Therefore, this method can both generate *and* verify crypted passwords.
(Inherited from Crypter.)
Public methodGenerateSalt
Generates a salt string with default options. The purpose of salt is to make dictionary attacks against a whole password database much harder, by causing the crypted password to be different even if two users have the same uncrypted password.
(Inherited from Crypter.)
Public methodGenerateSalt(Int32)
Generates a salt string using the specified number of rounds. The purpose of salt is to make dictionary attacks against a whole password database much harder, by causing the crypted password to be different even if two users have the same uncrypted password.
(Inherited from Crypter.)
Public methodGenerateSalt(CrypterOptions)
Generates a salt string. Options are used to modify the salt generation. The purpose of salt is to make dictionary attacks against a whole password database much harder, by causing the crypted password to be different even if two users have the same uncrypted password. Randomness in a crypted password comes from its salt string, as do all recorded options. The same salt string, when combined with the same password, will generate the same crypted password. If the salt string differs, the same password will generate a different crypted password (crypted passwords have the form algorithm+salt+hash, so the salt is always carried along with the crypted password).
(Overrides CrypterGenerateSalt(CrypterOptions).)
