Class Asymmetric

Namespace

SunamoShared.Crypting

Assembly

SunamoShared.dll

Asymmetric encryption uses a pair of keys to encrypt and decrypt. There is a "public" key which is used to encrypt. Decrypting, on the other hand, requires both the "public" key and an additional "private" key. The advantage is that people can send you encrypted messages without being able to decrypt them.

Constructors

Asymmetric()

Instantiates a new asymmetric encryption session using the default key size (usually 1024 bits).

public Asymmetric()

Asymmetric(int)

Instantiates a new asymmetric encryption session using a specific key size.

public Asymmetric(int keySize)

Parameters

keySize int

The key size in bits.

Properties

DefaultPrivateKey

Returns the default private key as stored in the *.config file.

public Asymmetric.PrivateKey DefaultPrivateKey { get; }

Property Value

Asymmetric.PrivateKey

DefaultPublicKey

Returns the default public key as stored in the *.config file.

public Asymmetric.PublicKey DefaultPublicKey { get; }

Property Value

Asymmetric.PublicKey

KeyContainerName

Sets the name of the key container used to store this key on disk; this is an unavoidable side effect of the underlying Microsoft CryptoAPI.

public string KeyContainerName { get; set; }

Property Value

string

KeySizeBits

Returns the current key size, in bits.

public int KeySizeBits { get; }

Property Value

int

KeySizeMaxBits

Returns the maximum supported key size, in bits.

public int KeySizeMaxBits { get; }

Property Value

int

KeySizeMinBits

Returns the minimum supported key size, in bits.

public int KeySizeMinBits { get; }

Property Value

int

KeySizeStepBits

Returns valid key step sizes, in bits.

public int KeySizeStepBits { get; }

Property Value

int
