Encrypt(Byte[], RSAEncryptionPadding)

Source:: RSA.cs

Source:: RSA.cs

Source:: RSA.cs

When overridden in a derived class, encrypts the input data using the specified padding mode.

public:
 virtual cli::array <System::Byte> ^ Encrypt(cli::array <System::Byte> ^ data, System::Security::Cryptography::RSAEncryptionPadding ^ padding);

public:
 abstract cli::array <System::Byte> ^ Encrypt(cli::array <System::Byte> ^ data, System::Security::Cryptography::RSAEncryptionPadding ^ padding);

public virtual byte[] Encrypt(byte[] data, System.Security.Cryptography.RSAEncryptionPadding padding);

public abstract byte[] Encrypt(byte[] data, System.Security.Cryptography.RSAEncryptionPadding padding);

abstract member Encrypt : byte[] * System.Security.Cryptography.RSAEncryptionPadding -> byte[]
override this.Encrypt : byte[] * System.Security.Cryptography.RSAEncryptionPadding -> byte[]

abstract member Encrypt : byte[] * System.Security.Cryptography.RSAEncryptionPadding -> byte[]

Public Overridable Function Encrypt (data As Byte(), padding As RSAEncryptionPadding) As Byte()

Public MustOverride Function Encrypt (data As Byte(), padding As RSAEncryptionPadding) As Byte()

Parameters

data: Byte[]

The data to encrypt.

padding: RSAEncryptionPadding

The padding mode.

Returns

Byte[]

The encrypted data.

Exceptions

ArgumentNullException

data or padding is null.

NotImplementedException

A derived class must override this method.

CryptographicException

padding is unknown, or not supported by this implementation.

-or-

The length of data is too long for the combination of KeySize and the selected padding.

-or-

The encryption operation failed.

Exceptions

ArgumentNullException

padding is null.

CryptographicException

padding is unknown, or not supported by this implementation.

-or-

The length of data is too long for the combination of KeySize and the selected padding.

Source:: RSA.cs

Source:: RSA.cs

Source:: RSA.cs

Encrypts the input data using the specified padding mode.

public:
 int Encrypt(ReadOnlySpan<System::Byte> data, Span<System::Byte> destination, System::Security::Cryptography::RSAEncryptionPadding ^ padding);

Public Function Encrypt (data As ReadOnlySpan(Of Byte), destination As Span(Of Byte), padding As RSAEncryptionPadding) As Integer

Parameters

data: ReadOnlySpan<Byte>

The data to encrypt.

destination: Span<Byte>

Exceptions

ArgumentNullException

padding is null.

ArgumentException

The buffer in destination is too small to hold the encrypted data.

CryptographicException

padding is unknown, or not supported by this implementation.

-or-

The length of data is too long for the combination of KeySize and the selected padding.

-or-

The encryption operation failed.
