Class Kalyna256

Namespace
CryptoHives.Foundation.Security.Cryptography.Cipher
Assembly
CryptoHives.Foundation.Security.Cryptography.dll

Kalyna-256 symmetric cipher implementation (DSTU 7624:2014) with 128-bit block.

public sealed class Kalyna256 : SymmetricCipher, IDisposable
Inheritance
Kalyna256
Implements
Inherited Members

Remarks

Kalyna-256 uses a 128-bit block with a 256-bit key (14 rounds). This provides a higher security margin than Kalyna-128.

Constructors

Kalyna256()

Initializes a new instance of the Kalyna256 class.

public Kalyna256()

Fields

KeySizeBits

Key size in bits.
