Argon2 Constructor

Namespace: Rebex.Security.Cryptography

Assembly: Rebex.Security.dll (version 7.0.9119)

Argon2(Argon2Configuration, Byte[], Byte[], Byte[], Byte[])

Initializes a new instance of Argon2 class.

Declaration

public Argon2(Argon2Configuration configuration, byte[] password, byte[] salt, byte[] key, byte[] associatedData)

Parameters

Type	Name	Description
Argon2Configuration	configuration	Argon2 configuration.
Byte[]	password	The password used in DeriveBytes method. Parameter 'P' from Argon2 specification. When a null value is specified, the password is treated as an empty array.
Byte[]	salt	The salt used used in DeriveBytes method. Must be at least 8 bytes long. Parameter 'S' from Argon2 specification.
Byte[]	key	The secret key used in DeriveBytes method. Parameter 'K' from Argon2 specification. When a null value is specified, the key is treated as an empty array.
Byte[]	associatedData	The associated data used in DeriveBytes method. Parameter 'X' from Argon2 specification. When a null value is specified, the associatedData is treated as an empty array.

Remarks

• The instance of Argon2 class creates, uses, and clears a copy of the password.
• The instance of Argon2 class is not the owner of the password.
• The instance of Argon2 class creates, uses, and clears a copy of the salt.
• The instance of Argon2 class is not the owner of the salt.
• The instance of Argon2 class creates, uses, and clears a copy of the key.
• The instance of Argon2 class is not the owner of the key.
• The instance of Argon2 class creates, uses, and clears a copy of the associatedData.
• The instance of Argon2 class is not the owner of the associatedData.

Exceptions

Type	Condition
ArgumentNullException	The configuration is null or the salt is null.
ArgumentException	The salt has length less than 8 bytes.

Argon2(Argon2Configuration, Byte[], Byte[], Byte[])

Parameters

Type	Name	Description
